The result is the emergence of shots movement that does not pay much attention to aesthetic aspects

Double glass facade system consists of two shells in order that the air in the cavity flows between them. Natural or mechanical ventilation hole can be performed (Figure 3). Apart from the cavity conditioning, air source and destination based on climate, land use type, location and time of construction is different. Glass skins can be single or double the distance of 20 cm to 2 meters from each other. Often the protection and counter the heat loss in cold periods, shading devices are used in the inner cavity.
Functionality and features double perspective view of a wall is like the sun. However, because there is a further layer of a thermal buffer layer is formed which reduces heat loss and take advantage of Stew provides indirect. In the heat (cold) pre-heated air can be breathed into the building to natural ventilation and indoor environment more favorable (Figure 2). In the scientific literature, various definitions of the facade system is provided that for example the two cases mentioned.
Claessens and DeHerde exterior walls are defined as "secondary view, an extra shell is installed portable air conditioners on the facade and often transparent. Back empty space between primary and secondary shell buffer space that the building is isolated. The space to fit the arrow can be heated by the sun. Structures to the south, the air heated by the sun for heating purposes during the cold winter months are used. However, at other times this season and is air conditioned. "
Belgian Building Research Institute Handbook (BBRI) (2002) defines these views as "active facade (exterior walls) show that one or more floors of a building with multiple skins transparent covers. These layers portable air conditioners can be attributed to air insulated or not. The shots of the empty space between the shells can be natural or mechanical ventilation. This space ventilation strategy on time. The facade systems and tools to improve the internal environment using active or passive techniques have been integrated. In most cases, this set automatically by the control system, are managed.
In the scientific literature of the system called portable air conditioners different names: Double-Skin Façade Active Façade portable air conditioners (usually when the air cavity portable air conditioners ventilation portable air conditioners is mechanical) Passive Façade (usually when the air cavity ventilation is natural) Double Façade Double Envelope (Façade ) Dual-Layered Glass Façade Dynamic Façade Wall-Filter Façade Environmental Second Skin System Energy Saving Façade Ventilated Façade Double-Leaf Façade Energy Saving Façade Environmental Façade Multiple-Skin Façades Intelligent Glass Façade Second Skin Façade / System Airflow Window Supply Air Window Exhaust portable air conditioners Window / Façade Double Skin Curtain Wall Twin Skin Façade
The idea of a double façade consists of the following layers (Figures 4 and 5): exterior: one layer is usually transparent glass. The shell can be entirely glass. Inside view: the windows are double glazed. The shell is usually entirely of glass. Cavity air space between the two shells. Within this space can vary from mm200 to m2. The maintenance interval indicator on impact. Internal windows can be opened by the user. This can lead to natural ventilation room. Automatic shading system is embedded portable air conditioners within the space.
The result is the emergence of shots movement that does not pay much attention to aesthetic aspects, but there are other numerous benefits like less of a need for cooling or heating and cooling of the cost in the evening, as well as the cursor to the sound insulation buffer against air pollution. On the other hand some of the difficulties in view of the double glass wall compared with traditional features including excessive heat of summer and summer (Figure 6), the cost of investment additional portable air conditioners charges portable air conditioners building reduction usable space maintenance ( Baldinelli, 2009).
Saelens, (2002) believes that in 1849, the then director of the Industrial Museum in Brussels, Jean-Baptiste Zhvbard, the original form of multiple view that mechanical ventilation is provided. He explained how warm in winter portable air conditioners and cool in summer must be between the front shell.
Crespo Mtsd the first instance of double ups in 1903 and is based in Germany. At the time, the goal of maximizing the use of daylight portable air conditioners with regard to cold and harsh winds in the region. The solution has been offered a three-storey building portable air conditioners on the ground floor for storage and the other two were used for the workplace. It was successful portable air conditioners in achieving its objectives and phases of development that is similar in 1904 and 1908 were built.

As a result, governments andrea antonelli and multilateral measures consumer awareness, today, energy andrea antonelli consumption is one of the main factors in selecting the type of air conditioning system. On the other hand, to raise the level of customer satisfaction and compliance with the new rules, the energy consumption of factories also heavily involved in improving the productivity and performance of air conditioning systems themselves.
Reduce power consumption, easy operation and reliable performance than other HVAC products, has led to today VRF systems as one of the most modern ventilation systems are known. Wide range of innovative technology and smart features used in these systems, and the ability to create exceptional heating and cooling, resulted in VRF systems every day to find more fans in the world.
In the not too distant andrea antonelli past most central cooling system, chiller types, respectively. Today, with more engineers every day VRF technology invented these devices are selected as the best ventilation. Heating and cooling capabilities by providing a fully integrated system with control unit, no need to keep the engine house and technicians, as well as low power consumption and coefficient of performance (COP) of the component devices VRF especially in times, the number of the advantages of This is the type of system.
LG's Multi VRF air conditioners take advantage of the technology. This type of device andrea antonelli includes an external unit and several units have been built and the capacity of 80 thousand to 800 thousand BTA UPS are available. Kndasvr external andrea antonelli unit includes compressor, intelligent brain and machine ... and a pair of sweep refrigerant pipes connected to it. But it can split a pair of pipes and several dozen internal units (up to 64 units) that play a role in the evaporator, a condenser connected.
The possibility of long distance pipeline, a project to install high, the possibility of installing an internal units of different types, the central controller utilizes refrigerant R 410 a more environmentally friendly and also do not need to drink water, some of the reasons Consulting widely and increasingly used for this system.
The coefficient of performance (COP) of his multi-device 4 (in the capacity of two hundred thousand BTA U) equals 4.85 and improves efficiency at part load (IPLV) is equal to 6, which means 30 ~ 15% efficiency andrea antonelli at full load and 40 ~ 20% efficiency at part load than the 3 series is multiplayer. andrea antonelli The reasons for the increased efficiency of the new technologies used in this series of multimedia devices is that he goes on to describe some of them below.
Inverter compressor: the compressor used in the Multi Series 4, inverter (variable speed) andrea antonelli and this means that the rotation speed of the compressor to reduce the amount of time required increases and no longer in charge of the minor compressor with capacity to work. However, his multi-compressor 4, the fourth generation of Askral LG compressor is unique and features. Previous series compressor range 20 to 120 Hz were working, while the scope of the new series from 15 to 150 Hz increased and this means less power consumption at part load and compressor power is increased by 25%.
steam injection technology and Haypvr: by taking advantage of the steam injection technology (Vapor Injection) in the new series, the heating capacity of the system can be increased by 27% even when the ambient air temperature is 25 degrees Celsius below zero , Grmabkhsh indoor room.
Haypvr (HIPOR), a leading industrial technology and LG are monopolized by the return of oil at high pressure directly into the compressor, reduces andrea antonelli the efficiency of the overall performance of energy dissipation and is a.
Intelligent andrea antonelli control the amount of refrigerant: LG researchers found that the proportion of circulating refrigerant cycle device with temperature has a big impact on energy consumption. He is a multi-purpose device 4 is able to help your refrigerant tank and intelligent flow of refrigerant in the cooling cycle based work, heating or time relative decrease or increase. andrea antonelli
Oil Control Smart older models, every eight hours to retrieve the oil in the pipes action and returns to the compressor. But modern technology LG sensor units, each time the compressor oil and check the oil level in the compressor is reduced only when the oil begins to recover. This will cause the number of recoverable oil has fallen sharply, resulting in energy andrea antonelli saving.
The number of variable passes the condenser: Another finding of the R & D suggests that the number of passes condenser tubes (refrigerant flow path) as well as the speed of the refrigerant in the system has a direct impact on COP. LG's fourth series of multi-purpose technology andrea antonelli "variable number of passes" is a benefit. This means that according to the heating or cooling of the refrigerant pipe passes the external unit and therefore the speed at which the refrigerant is variable.
This technology also enables the device provides increased efficiency in projects such as sports clubs or server andrea antonelli rooms that require cooling even in winter, the temperature, even when it 10 degrees Celsius reduced andrea antonelli could be cooling performance.
Maximum height difference andrea antonelli between andrea antonelli internal units in the previous models, the maximum allowable height between indoor unit

After the energy gas fireplace crisis in 70 AD, the idea was introduced fundamental changes in the exteriors of buildings. The emergence of the idea of philosophy, to achieve the best level of thermal comfort in a variety of weather conditions, combined with the highest amount of natural light from one side and the other side was energy efficiency. gas fireplace The use of glass with a special performance by the sun and solar energy (glass V-Cool) and views the idea is the result of two shells. Read more discussion on the introduction of a variety of shots and then pay them double and features a view of the economic performance of the second shell was introduced by Al-Wall connections. .
The facades of the shell structure consisting of two (not necessarily transparent outer surface) which are separated by a space. Air space acts as a channel. This channel or chamber having an important role in acoustic and thermal insulation of facades of the crust.
Promoting the use of such schemes is increasing rapidly. Term views of the two shells into a large group of systems that is similar in appearance and in reality are very different. In order to classify the type of system should first look to the 3 major differences between them:
The most recent innovation in the field of view is the crust. The use of natural ventilation air, reduces the use of mechanical ventilation systems and better gas fireplace thermal comfort gas fireplace with minimum energy consumption associated with the residents. The gap between the design of systems with natural ventilation (type III) according to the desired ventilation function is divided into 4 categories:
1. The second shell features an integrated (multi - story facade): The inclusion of such projections and integrated interior space is low. The advantage of opening a second front in addition to natural ventilation, maintenance and cleaning gas fireplace of the facade as well.
2 shots in the second shell corridor (Corridor Facade): In this type of shots horizontally central space on each floor will be closed. The advantage of this type of segmentation, allowing natural ventilation is better to transfer the sound of interior spaces (rooms) to each other,
3. The second shell pack shots (Box- Window Facade): In this window horizontally and vertically around the interior shots are closed. An important advantage of this method of the central space, avoiding the transfer of odor and noise in the interior (room), but it does not come natural ventilation.
Column 4 shots a second shell (Shaft- Box Window): The interior space is divided vertically. The division of thermal and acoustic insulation performance has improved and the number of smaller openings in the exterior is required.
In multi-storey buildings, especially in situations where high levels of exposure to wind pressure and noise pollution, the use of natural ventilation features of the shell using a very efficient and effective. Factors such as sound insulation requirements, air flow rate in the central gas fireplace space, the outer perimeter of the building, the type, number and location of openings in each inner and outer bilayer, have a direct impact on the design gas fireplace of this type of shots.
In view of the double-shell design and evaluation should be considered only as an economic factor. Residents of other issues such as thermal comfort and beauty should be equally considered. Especially when the second shell is designed to rehabilitate an old building. Because in addition to improving the performance of the exterior, the new size of the building.
Venus Glass Company gas fireplace in cooperation with the Austrian Langle Glas facade design and execution of the second shell in its agenda. gas fireplace This system is one of the simplest, most efficient and most economical installation Nmast glass outer shell.
Sort glass, gas fireplace as well as flaky coating is formed using the clamp connections. Sort flake-shaped glass can be both horizontally and vertically. This arrangement creates a gap between each layer is adjacent glass bottle. The distances through the air to the desired shape of the inner space of flows.
Interior design can be different gas fireplace each of the four facades of the shell model with natural ventilation cover. Design, interpretation and selection of the appropriate glass for acoustic and thermal insulation performance, safety and supplying glass jar Venus is the responsibility of the company. With the election just glass and secure gas fireplace for their operations and taking into account the wind direction gas fireplace and the arrangement in accordance with the view of the glass can be designed and implemented function eggshell.

Saturday, Persian date Khordad 31 1393 Posted in miscellany published aidy bryant by Babak valizadeh Be the first to comment! Photo gallery of the new generation of air conditioners LG Multi V unveiled
The first day in the heat of summer 1393 Football World Cup arrives tomorrow and certainly all of us are looking for ways to head off a lot of heat. Homes and small offices that are located in buildings of three or four each as different solutions to this problem, but the situation is very serious when a large and complex set Rooms Arvbrv of the building and board it. This is the new generation of air conditioning systems, LG Multi V officially aidy bryant announced last week, will be taken Zmam Affairs and an enjoyable summer (and winter warm!) For us to strive.
Reduce power consumption, easy operation and reliable performance than other air conditioning systems, has led to today VRF systems as one of the most modern ventilation systems are known. Wide range of innovative technology and smart features aidy bryant used in these systems, and the ability to create exceptional heating and cooling, has caused VRF systems every day to find more fans in the world. New Generation aidy bryant LG Multi V systems with a focus on greater energy efficiency and customer satisfaction has been designed and developed. Multi V A + energy consumption of the new standard and is supported by a series of products aidy bryant offered in cooperation with Gldyran the domestic aidy bryant market.
In the not too distant past most central cooling system, chiller types, respectively. Today, with more engineers every day VRF technology, these devices are selected as the best ventilation. Heating and cooling capabilities by providing a fully integrated system aidy bryant with a single control system, no need to keep the engine house and technicians, as well as low power consumption and coefficient of performance (COP) of high-pressure part of the VRF, especially in the just a number of advantages This type of system is the flagship. LG's Multi VRF air conditioners also take advantage of the technology. This type of device aidy bryant includes an outer and inner unit and several thousand BTU capacity of 80 thousand to 800 are available. Kndasvr external unit includes compressor, aidy bryant brain and other intelligent devices and a pair of sweep refrigerant pipes connected to it. But it can split a pair of pipes and several dozen internal units (up to 64 units) that play a role in the evaporator, aidy bryant a condenser connected. The possibility of long distance pipeline, a project to install high, the possibility of installing an internal units, the central controller utilizes refrigerant R 410 a more environmentally friendly and also do not need to drink water, some of the reasons widely Consulting engineers for the increasing use of the system.
The coefficient of performance (COP) of his multi-device 4 (in the capacity of two hundred aidy bryant thousand BTU) equal to 4.85 and improves efficiency at part load (IPLV) is equal to 6 (this is fifteen to thirty percent efficiency at full capacity and twenty to forty percent efficiency at partial loads compared to the Multi Series 3). The reasons for this increased efficiency, new technologies used in the series of his multimedia devices. Then when you see only a part of the new capabilities and technologies aidy bryant that have been used in the Multi V IV.
1. The inverter compressors: All units used in the Multi Series 4, inverter (variable speed) and this means that the rotation speed of the compressor to reduce the amount of time needed and no longer increases at part load compressor aidy bryant with capacity to work.
2. Haypvr steam injection technology by taking advantage of the steam injection technology (Vapor Injection) in the new series, the heating capacity of the system aidy bryant can be increased by 27% even when the ambient air temperature to 25 degrees Celsius below zero is Grmabkhsh indoor aidy bryant room. Haypvr (HIPOR), a leading industrial technology aidy bryant and LG is monopolized by the return of oil at high pressure directly into the compressor, reduce the waste of energy improve the performance of the overall performance of the back.
3. Intelligent control aidy bryant the amount of refrigerant: LG researchers found that the proportion of circulating refrigerant cycle device aidy bryant with temperature has a big impact on energy consumption. He is a multi-purpose device 4 is able to help your refrigerant tank and intelligent flow of refrigerant in the cooling cycle based work, heating or time relative decrease aidy bryant or increase.
4. Oil Control Smart older models, each eight hours of action to recover oil in the pipes and returns it to the compressor. But new technology LG sensor units, each time the compressor oil and check the oil level in the compressor is reduced only when the oil begins to recover. This will cause the number of recoverable oil has fallen sharply, resulting in energy saving.
5. The number of passes in the variable condenser Another finding of the R & D suggests that the number of passes aidy bryant condenser tubes (refrigerant flow path) as well as the speed of the refrigerant in the system has a direct impact on COP. LG's fourth series of multi-purpose technology "variable number aidy bryant of passes" is a benefit. This means that according to the heating or cooling of the refrigerant pipe passes the external unit and therefore the speed at which the refrigerant aidy bryant is variable. It also increases the efficiency

The basic needs of indoor air requires to room temperature regardless of outside weather conditions, goodman furnace at a desired level. In addition, the air inside the room to be clean and recyclable, and foremost to be of use to the temperature in the comfort of the building at all times be.
In addition, the seams are heat buildings is wasted in other words outside the cavity gaps in walls, floors, and windows inserted into the building. Keep in mind that the temperature inside the buildings to be kept for more than 20 C, which means that most of the heat in the heat of the internal structures of the use of devices goodman furnace equipment .mnab, the system is lighting occupational activities.
Usually the heat in residential buildings is relatively moderate heat loss .vdr more years are needed to supply heat to high heat. During the time of year when the windows are open. (The heat removal systems in residential buildings very rare in Sweden).
In fact, improved building standards so that they are isolated Vhvabndy, Vatlaf heat from the outer casing is very low. If Vbymarstanha office buildings goodman furnace and commercial buildings and industrial sectors look we should remember that late hours of the night and the temperature goodman furnace is Weekends are usually temperature rise occurs during working hours in order to reduce the heat to medium Aftd.bnabrayn simple thermal systems to enhance heat Weber photos .zrfyt systems require costly ventilation system to reduce the amount of heat that Bashdtyyn is.
Generally, the addition of heat accumulation Vbaltb adding capacity cooling system, providing favorable weather majority is difficult. After trying to design buildings that are most often be minimal accumulation of heat in the .anjam It requires a general attitude toward building, system goodman furnace implementation activities done on it.
In general terms, the heat removed from the buildings, in order to maintain goodman furnace the internal temperature is lower than the previous peak, it refers to the need for cooling air requirement of the building. In other words, in fact, is proportional to the heat added.

If necessary, prior to the introduction of air into other rooms, heated.
With a CAV system supplies air with a constant flow fan with two Mvtvrsry sometimes forces the cooling requirements of the building collapsed when the rotation speed is reduced. CAV systems using the engine speed should not interfere with VAV systems in order to control the cooling air flow rate can vary.
Variable air volume systems (systems VAV)

Familiarity with Vortex Tube technology for ventilation and air in the air for ventilation and air-conditioning cooling system is of two types, one Vapor-Cycle Machine and the other is called Air-Cycle Machine. VCM type, but the efficiency is slightly less expensive, so only suitable for home use as well, but for Hvapyna of ACM used car with a good efficiency. Nevertheless, the VCM is the only air cooling, PC-7 is, in fact, a military training aircraft (Military Training) respectively. But now a new generation of cooling systems Knddh celebrate the Vortex Tube expected due to its excellent benefits, both prior to take place soon. Vortex Tube is a tube that is streamlined for using a conventional compressed air source can deliver the kind of warm and cold air. Vortex Tube plane of the following advantages: 1. No moving parts, which in this case would be more life. 2. No need for electricity or chemicals Small and lightweight 3. 4. 5. low maintenance costs 6. No ability to deliver instant cold weather durable stainless 7. 8. Temperature adjustable by turning a handle 9 - capability to any compressed air source Vortex Tube an inexpensive, reliable and trouble-free maintenance costs for cooling point in the industry. Vortex Tube in three sizes provided. Random Vortex Tube in 1928 by George Rangue (French student in physics) was discovered. Mr Ranque when making a circulating pump, suddenly realized that pumps hot air from one end and the other end of the cold air out. After this incident, he left the bar, and the project construction will bring a cooler of Vortex Tube Due to the failure of the project was forgotten. In 1945, a German physicist named Rudolph Hilsch Vortex Tube project vent axia continued. It should be mentioned that Mr. James Clerk Maxwell, the great scientists of the 19th century physics research done in this regard. Namkamy reason for the postponement of the project can be attributed to non-availability of compressed air source. But in recent decades the problem vent axia Vortex Tube technology has been well developed. Vortex Tube Performance is based on a physical phenomenon. If this is how the Vortex Tube to 80PSI-100PSI air pressure of the compressed air supply off and tangentially into the orbital Mhfzh. At this moment, the angular speed of more than one million rpm and the temperature was increased. The air in the form of a battalion in the tunnel, the Vortex Tube moves. At the end of the Vortex Tube amount vent axia of hot air out of the control valve. The remaining air is still circulating in the opposite direction and moves around warm air from inside the tunnel. The air inside the mole turning their energy as heat to the surrounding air tunnel and the cold air out of the Vortex Tube. Vortex Tube serves as an inlet air pressure is between 20PSI to 250PSI, while optimum performance is at 80PSI to 110PSI. Vortex Tube can reach temperatures vent axia of cold weather to -46 C to 127 C and can reach a temperature of hot air. The Vortex Tube calculations have shown that the maximum cold compressed air inlet to the outlet can be up to 80%, which means that this component of the cold heat exchanger reaches its maximum. The experiments also show that the maximum cooling is achieved exactly when cold air outlet temperature of the inlet air temperature vent axia is below 28 C. The use of Vortex Tube as follows: (1) rapid cooling of the molten material out of the oven. 2. Keeping your cool sensitive electronic circuits and high voltage switchgear and power. 3-cooling and air conditioning of homes and offices. 4. Keep the fuel nozzle spray cooling vent axia large furnace to prevent melting. 5-cooled heat retaining washer and templates. 6-cooling point for the industry. Full of a Vortex Tube kit includes the following parts: 1-Vortex Tube 2-3-filtered cold air silencer 4-pipe clamps required 5-cap the price of a Vortex Tube Due to the size and equipment of $ 23 to $ 4,500 is

The doctors and experts, the risk to body temperature, 40 C (about argo dvd 104 F) is defined. From this point on, the efficiency decreases rapidly nervous system, the heart of the high pressure argo dvd imposed to the extent and function argo dvd of various organs is interrupted. When these conditions are associated with humidity, the situation is deteriorating. The human body is naturally able to withstand the weather is hot. Tests show that man can at 101 C (about 215 F) for 30 minutes to tolerate it. Often the case for athletes, especially in the field event Svarany bicycle pedal comes out. When the temperature rises, the heart works harder and the blood vessels dilate and more blood is pumped to the surface of the skin. At that moment, the body sweats the most important strategy for reducing the temperature inside the body. Evaporation of sweat on the skin surface cooling effect on the skin. Cold blood then returns to the heart and reduces the internal temperature. But when the humidity is high, things are not that simple. The body keeps the sweat and the sweat is not only reduces body temperature, but also reduces the amount of water and blood cells. Nervous system is very sensitive to increases in core body temperature. With increasing temperature, the brain becomes confused and decision-making power and short-term argo dvd memory is reduced. The condition may be a strange and unreasonable behavior Srbznd.

AutoCAD software is undoubtedly one of the most commonly used software engineering, especially in the establishment. Learn the basics of the program is required to use all features. Students and engineers have prepared for you a complete fireplace screen package fireplace screen for all versions of AutoCAD training is the foundation of all things simple but professional in its place, an engineer needs and you can make an exceptional price-12,500 Tumans Please fireplace screen buy the collection. You can also see other properties of this series continues.
In general, a wide range of systems that depend on which country you live in an area of your home and how you can use them for heating and cooling your home. Some of these models can easily solve many of your needs. The best and most common model, called fireplace screen the system fireplace screen unit. Because the system to an external fireplace screen source and is home to the source fireplace screen is required. Generally, a unit of an air conditioning system and an air conditioner with heat exchanger, an air conditioner, gas and coil, or a heat pump and air conditioner and heat tape backup can be made Ast.nyz a heat pump and a gas is formed. Split is located in front of the package. Instead of an external unit and an internal unit, the components of the system are assembled in a single box. Somewhat technical terms that you may encounter when you buy with it: 1.hrart central air conditioning, ventilation means air unit with electric heat strips builder. 2.pmp heating and air conditioning, air conditioning unit by means of heat pumps and heat tape backup. 3.hrart central air conditioner Package: Means a comprehensive package with electric heat strips. 4.mshl gas and air conditioners, split air conditioning system with a gas means the natural or IP. 5.thvyh air in the air, the whole system is basically the same act. For cooling the air inside your home from the inner coil passes. Absorbed heat from indoor air and cool air generated through the duct (inner tube) between your home flows. Heat your home through the outer coil. The rate is higher SEER, the more efficient the device will work. At the same time, thus improving system performance, the system better and more efficient, it will cost you less. 6.dstgah air conditioning and electric heat: efficiency for air conditioning systems is shown by the SEER rating (seasonal energy utilization ratio) indicating that a device uses with the utilization of electricity . The system of electric heat strips used as a heat source. The heat source is useful if you use too little or heat, oil and gas prices were much higher than electricity or if you have a heat source such as Base board heat. Thermal bands range in size up to 20KW is 5.7.10.15. Heat pump type air conditioner in the summer, the process of removing heat from the outside air and transfer it into the house in order to perform the winter to the It is not very effective temperatures Fahrenheit 30. In these areas, gas or air to help heat your home will be required. Among all electrical appliances electric torch or an air conditioner, heat pump uses less energy. In temperate fireplace screen climates need to buy a separate gas burner or fuel becomes less. This is despite the fact that the cold weather is not using them at all cost. However, where necessary heat pump with a gas can be adapted. Softened by the heat pump or where the gas temperature is smaller cycles can act. 7.dstgah air with a gas: utilization fireplace screen of a torch or AFUE (annual fuel utilization Use) tells you how much utilization fireplace screen of fuel burner uses. Torch with higher productivity means lower total costs are related fireplace screen to the heat. Torch with a high utilization rate AFUE% 80,% 90 96% or higher to offer. This is meant to reduce the monthly heating costs. Burning gas or oil burners heat the inside. Hot gases that are generated inside the metal tube called a heat exchanger passes through a plastic or metal tube is removed from your home. At the same time, the air inside your home is in circulation passes through the heat exchanger out of the iron is hot. The hot air circulation inside the house. (It is important to note that the most productive and most profitable gas pipe PUC to Vent (valves) are used. And maybe a hot water pipes, steam pipes, new chimney need to be set up. 8.yvnyt Package: In some parts of the country, a package system is the best solution. All facilities are exothermic, cooling fireplace screen and air operations are included in a complete unit on a flat surface, usually on the roof or out of the room (mobile room) to be installed. This system can be heat pump or electric head strips or a gas heater fireplace screen as the primary heat source. 9.yvnyt internal fireplace screen variable fireplace screen speed: if you have a variable fireplace screen speed air or a gas burner speed variable with unit wont buy certainly convenient to both productivity

The energy consumption is one of the main factors lux moms in selecting the type of air conditioning system. On the other hand, to raise the level of customer satisfaction and compliance with the new rules, the energy consumption of factories also heavily involved in improving the productivity and performance of their air conditioning systems.
Reduce power consumption, easy operation and reliable performance than other HVAC products, has led to today VRF systems are recognized as one of the most efficient modern ventilation systems. Wide range of innovative features lux moms and smart technology employed in the system, and the ability to create exceptional heating and cooling, has caused VRF systems every day to find more fans in the world.
In the not too distant past most central cooling system, the types of chillers. Today, with the invention of technology VRF, every day more and more engineers will select the device type as the ventilation system. Heating and cooling capabilities by providing lux moms a fully integrated system with a single control system, no need to keep the engine room and technicians, as well as low power consumption and coefficient of performance (COP) of VRF systems, especially at partial loads, only a few of the advantages of the type system.
Mvltyvy LG VRF air conditioning systems utilize technology. The device consists of a number of internal and external unit and the capacity of 80 thousand to 800 thousand BTA Yu exist. External unit includes a condenser, compressor, intelligent brain and machine ... and a pair of sweep refrigerant pipes connected to it. But it's a pipe coupling lux moms can be multiple branches and dozens of internal units (up to 64 units), the operator plays the role as a condenser connected. Plumbing possibility of large distances, can be installed in high projects, the possibility of installing an internal units of different types, the central controller and the use of refrigerant R 410 a friendly environment as well as the need to drink water, some of the reasons for the increasing widely Engineers Counsel for the use of this system.
He coefficient of performance (COP) devices Mvltyvy 4 (in the capacity of two hundred thousand BTA U) equals 4.85 and improves efficiency at partial loads (IPLV) announced it 6 times and said this would mean 30 ~ 15% efficiency 40 ~ 20% increase in capacity and efficiency at partial loads than Mvltyvy Series 3. The reasons for this increased efficiency, new technology used in this series of devices Mvltyvy who went on to describe some of them below.
All compressors lux moms used in Mvltyvy Series 4, inverter (variable lux moms speed) and this means that the rotation speed of the compressor to reduce the amount lux moms of time needed and no longer increases the partial loads, with a maximum compressors work a. The compressors Mvltyvy 4, fourth-generation LG Askral compressors and unique features. Previous series lux moms compressor lux moms range 20 to 120 Hz. They had, however, something new series range from 15 to 150 Hz increased and this means less power consumption at partial loads and 25% increase in the compressor power.
By using steam injection technology (Vapor Injection) in the new series, the heating capacity of the system can be increased by 27% even when the ambient air temperature is 25 degrees Celsius below zero, Grmabkhsh indoor room.
LG researchers found that the proportion of the amount of refrigerant circulating in the cycle, the temperature has a significant impact on energy consumption device. lux moms For this purpose, lux moms the device is able to help Mvltyvy 4 refrigerant tank and intelligent, the amount of refrigerant in the cooling cycle based on the function, the relative decrease or increase supply or load.
In older models, each eight hours of action to recover the oil in the pipe and returns to the compressor. But there is a new technology company LG sensor units, lux moms each time the compressor oil and check the oil level only when the compressor is reduced, oil recovery starts. lux moms This will cause the number of recoverable oil has fallen sharply, resulting in savings in energy consumption.
Another result of the R & D suggests that the number of passes of the condenser tubes (refrigerant flow path) and the speed at which the refrigerant has a direct impact on system COP. To this end, the fourth lux moms series of technology LG Mvltyvy lux moms "variable number of passes" is better. This means that according to the heating or cooling of the refrigerant tubing passes the external unit and therefore the speed at which the refrigerant lux moms is variable.
This technology, in addition to increasing the efficiency of the system, also provides the opportunity to participate in projects such as sports clubs or server rooms that require lux moms cooling even in winter, even when the air temperature lux moms is lowered to 10 degrees Celsius below zero, a performance is cooling.

Ventilation caused by piston moving with different water heater speeds of vehicles inside the tunnel air velocity caused by the pressure difference inside the tunnel water heater Grdd.bsth a one-way or two-way traffic of the tunnel as well as the number water heater of cars that pass through the tunnel, Each piston air in the tunnel, there is a possibility that the vehicle moves inside the tunnel effect is similar to a piston inside a long tube. The effect of the pressure difference between the front and rear cars (pressure maxing in front and rear) force make the air inside the tunnel to Move. Through the air flow is generated depends on the following factors: type of vehicle speed aerodynamic characteristics of the geometric characteristics of the tunnel aerodynamic vehicles water heater
Drtvnl air conditioning system in the form of longitudinal force (mechanical ventilation) flows .shdt air flow depends on the extent of contamination and hence increases with increasing length of the tunnel. In this way, you can install a booster fan to accelerate the airflow in the tunnel. Longitudinal ventilation water heater can be done in 3 ways:
Using the longitudinal ventilation fan: The beginning and end of the tunnel by installing a blower fan and sucking air through the tunnel to get moving. This method only works for one-way tunnels and tunnel air is blown in the direction of the piston effect and natural ventilation to help it. The air velocity is constant and the concentration of pollutants in the tunnel at the entrance to the tunnel water heater entrance from zero to maximum at the outlet is changed. Advantages: - reduce aerodynamic resistance and thus reduces the energy consumption due to the use of air to pass all sections of the tunnel. - Lack of space tunnel - no need for a large initial investment - low costs of operation and maintenance
Cons: - The major problem water heater with this approach is that it may be due to changing weather conditions, natural ventilation flows in the opposite direction during mechanical ventilation function. - - Inefficiency in bidirectional tunnel - air speed limits in the tunnel (to avoid causing inconvenience to passengers) between 8 and 10 Mtrdrsanyh
Longitudinal ventilation with the Devil: The way a channel dug in the center tunnel and the fan installed Quotient through the fan air intake, the air entering from the sides of the Channel tunnel exits. In this way, the air velocity in opposite halves of the tunnel. Due to the use of this method of explaining the bidirectional tunnel can be avoided this way.
Longitudinal ventilation using a Jet fan: The procedure to install water heater the jet jet fan in the ceiling of the tunnel, the air in the upper section of the tunnel geometry to flow out and air conditioning water heater Dhym.rvsh perform longitudinal length of one of the most common methods of Tunnel ventilation water heater is. Advantages: - No need to build a fan Qk Ata - Ability to manage water heater energy consumption (can be adjusted according to the amount of traffic off the number of fans. - Compatibility with piston effect caused by moving vehicles - the flexibility to make changes water heater in circumstances Joy. (using jet fans that have the potential to reverse the flow direction of air flow can be managed according to the normal flow direction. - Easy to install
Cross ventilation: The fresh air through a canal across the entire length of the tunnel into the weather back through the network to be sucked back into the channel. Blower and suction channel cross section varies along the tunnel and the tunnel air is usually imported from the ceiling out. If the entry and exit of air to be located diagonally to each other so that the lateral water heater side walls (Literal transverse) is called. water heater Advantages: water heater - uniformly throughout the tunnel ventilated. - The risk of spread of smoke and fire and the focus will be less pollution. - Uniform air pressure in the tunnel
Semi-transverse ventilation, air conditioning semi-transverse, water heater longitudinal and transverse combination of methods. water heater In this way the entire length of the tunnel into the fresh air and polluted air into the conduit throughout the tunnel and on leaving the tunnel is embedded sucked water heater sent, will. The

After testing the prototype in Iceland and the Netherlands, the predicted heat transfer efficiency of 95% answered. Dr20 degree temperature difference between the air inside and outside the fan 4 watt heat exchange capacity of 50 cubic meters per hour, 320 watts of thermal energy store. Traditional electrical efficiency of 40% with the energy storage capacity is 300 watts. vks So the total energy output vks window Nafs (box) 89% of the heat exchanger system wire is only 18 psi pressure vks and fan Nafs windows in the prototype, about 30 db sound that should be considered in a later version . A number of obstacles in system installations can be clearly seen today are: 1. The quality of outdoor air, indoor air quality houses vks in the Netherlands has had some remarkable vks results. According to research house Evert Hasselaar Dr500 different vks group, it was concluded that 3/2 homes with mechanical ventilation, due to dirty air capacity declined by about 10% per year due to persecution and sometimes vks the engine sound conditioning mechanical cut. Another discovery was that the 5/4 houses, natural ventilation room main bedroom had a small 2-seater that in 29% of these homes due to traffic noise, even at night was to open the window. CO2 concentration is very high and very fine dust was found in the house. vks Also the bathroom 3 times a day for showering commonly used "air-drying was very small and it was dark spots appear. Another point is that a significant difference between the internal bath and shower that there was only one window Drdyvar exterior walls and clay baths that have been drawn up with a low level easier to clean the facility Shdnd.2-: the study of existing ventilation building residential, commercial and industrial Netherlands shows that many differences between vks the results predicted and what is actually achieved. Mvsrbartnd of ideas, design, supply, implementation, monitoring, implementation, use and maintenance and a great deal based on the phase errors are there.

All heating systems, ventilation, air conditioning system without localization by design consultants that are usually "hidden in the ceiling and the ceiling to hide the air duct is used, about 15% of the building's capture.
3. Review of the facility, the facility houses are actually due to the annoying sound of the valve steel heat exchanger quick and dirty room, the ceiling and the residents will not be welcomed. Larger installations are "more frequently but need more space and produce a lot of heat, which means less comfort and high cost of heat and cold is the maximum load.
4. Use and storage: vks advancing toward the long-term good. Survey research shows that heat exchanger home with air conditioning barely kept the balance is blocked vks with dust. Also 3/2 of mechanical ventilation that is actually specified in the bylaws to provide free air flow will not build new buildings. Consumers generally do not have any comment on the mechanical behind their impact in terms of mechanical vks ventilation in large buildings, buildings that are considered repugnant to people who have a sense of imprisonment in the sense of embedded inappropriate technology in the drop-down window dissolves . New high-efficiency ventilation: We start again from scratch, a good building, a stable architecture and Vhvshmnd behind their guests vks are relaxed. Nafs been thinking for years about the idea of making a window and how it is accessed, or in what form, is still not generally known. World-wide investigation of the heat exchanger has lasted vks many years and finally to show a heat exchanger that was invented by a doctor ir.noorvan andel, was scored (Fig. 3V4) Dimensions for the selected window is synchronized with traditional exterior wall insulation is composed of two layers and depth.
The prototype consists of a transparent combination of cross-flow heat exchanger with mm80 * 180 * 450 which is less than the heat exchanger WIRE kg 1 body weight and easy to wash the washing is the standard.
Sensors of CO2 concentration in ppm 500 to Tvratvmatyk is clear, also at a concentration of 1200 ppm of a signal light, and when the concentration of 1700 ppm was a sound mark means opening certain doors and window to keep the air inside can be heard . The following question arises:

Heat your home through worcester boilers the outer coil. The rate is higher SEER, the more efficient the device will work. At the same time, thus improving system performance, the system better and more efficient, it will cost you less. Electric Heating ventilation and air 6.dstgah Productivity for air conditioning systems is shown by the SEER rating (Seasonal Energy utilization ratio) that indicates whether a device consumes electricity utilization . The system of electric heat tape is used as a heat source. The heat source is useful if you or your use of very low temperatures, oil and gas prices were much higher than electricity or heat source if you're like Base board heat. Thermal spectrum bands in sizes up to 20KW is 5.7.10.15. A heat pump air conditioning unit in the summer of process out of the house to absorb worcester boilers and transfer it to the outside worcester boilers air in the winter. This process will do to temperatures of about 30 degrees is very effective. In these areas, gas or air to help heat your home will be required. Among all electrical worcester boilers devices from the burner electric worcester boilers heat pump or air conditioner consumes less energy. In temperate climates need to buy a separate gas burner or fuel is less. However, in cold climates, it is not effective at all. However, where necessary with a gas heat pump can be adjusted. Milder temperatures in the heat pump or where the gas can act in a smaller cycle. 7.dstgah ventilated with a gas: utilization of a torch or AFUE (annual fuel utilization Use) tells you the torch with the utilization rate of fuel use. In the burners with higher productivity means lower costs are related to the heat. Burners with a high utilization rate AFUE% 80,% 90 96% or higher to offer. This is meant to reduce the monthly cost of heating. Burning gas or oil burner heating the inside. Hot gases that are generated inside the metal tube called a heat exchanger passes through a plastic or metal tube is removed from the home. At the same time, the air inside your home is in circulation passes through the heat exchanger outside the iron is hot. The hot air circulation inside the house. (It is important to note that the most efficient and useful to pipe gas from the PUC to Vent (valves) are used.

Hello good people! I am looking for a film camera. baseboard I feel I'm ready for the step up from DSLR filming, because now I've been at it a good period and I will get me away from 4: 2: 0 and h.264. Just as a little baseboard background info, I filmed a lot with DSLR from Canon and Nikon, mainly in 5D2 and 5D3. The two cameras I've looked at most Canon C100 and Blackmagic Cinema Camera, which BMCC is undoubtedly the most interesting. C100 costs around 41.000, - and a camera baseboard with many benefits, but the biggest drawback is probably the limited video quality you get 24Mbps AVCHD. Only the camera saves on SD card says well enough that there are limited quality one gets here. This is where Black Magic comes in. To 25,000 - gets 2.5k raw files stored right on SSD. Now we're talking. But then comes the limitations of BMCC. BMCC - Advantages Cheap! 25k 2.5K RAW 1080p ProRes Bright Bright picture! A dream! Thunderbolt I / O DaVinci Resolve 13 stop dynamic range BMCC - Disadvantages 2.3x crop factor on Canon optics baseboard my not so good battery life Fixed battery Not ergonomic; must have rig / Extras Not XLR audio; no phantom Expensive storage media ISO 1600 highest LONG delivery! Huff ... C100 - Benefits optics my go right on LONG battery life Replaceable battery 20,000 ISO (!) 2x XLR with phantom C100 - Disadvantages Many money for 24Mbps
