The heating design and energy saving of tall space buildings are important factors restricting the future development of tall space buildings. Tall space buildings can bring great comfort to users, but also have high requirements for building design. Due to the particularity of its space, such as heating facilities and other equipment are not ideal, and the requirements for professional technology and equipment and design are more strict.Therefore, also to our country at present tall space building hVAC design and energy saving work brought a certain pressure and obstacles, but tall space building is an important trend of the future construction development, so relevant departments must strengthen for tall space building HVAC design and energy saving problem pay attention to degree, and take effective measures to solve the relevant problems as soon as possible,Raise tall space building HVAC design level and energy saving level, push our country tall space building development.

	Gas infrared radiation heating system is based on the principle of solar radiation heating the earth surface, with natural gas, liquefied petroleum gas and other combustible gases as energy sources, burning in a special combustion device, and then through a special radiation tube to radiate specific wavelengths of infrared radiation for heating.


	 


	The use of gas infrared radiation heating system also has certain limitations.According to the "Heating ventilation and air conditioning design Code" (GB50019-2003) : "The installation height of gas infrared radiator should be determined according to the comfort of human body, but should not be less than 3m", the system is suitable for the height of more than 4m tall space heating, such as tall factory, car (machine) warehouse, large volume exhibition hall, hall, gymnasium and other places.For industrial plant, the rationality of the scheme should be discussed according to the specific conditions of the production process.For example, a large amount of dust, fiber, volatile, flammable, corrosive gas (fog) and other workshop space produced in the production process is not suitable for gas radiation heating system.


	 


	In terms of fire safety, many customers and designers believe that the use of gas radiation heating system requires the introduction of natural gas and liquefied petroleum gas pipelines into the workshop, which is bound to increase the risk and improve the fire risk level of the building.This will cause problems for all professional design.The concern about fire safety is mainly caused by the lack of understanding of the safety measures of the equipment itself and the operating status of the system.


	 


	The combustion of gas infrared radiation heating equipment can only be carried out when there is negative pressure in the radiation pipe, and the system pipes, valves and other gas are strictly sealed without leakage;The burner is equipped with automatic ignition device, no deflagration ignition phenomenon;With flameout protection device, high wind pressure safety device, flue blocking safety device and failure, loss of power, misoperation and other safety protection device.Customers should pay attention to whether the equipment has the effective inspection report provided by the National gas Appliances Quality Supervision and Inspection center when choosing the gas radiation heating equipment.


	 


	In addition, according to the "Heating ventilation and air conditioning design Code" (GB50019-2003), the building using gas radiation heating system should be set up combustible gas alarm device.Once there is a gas leak alarm, it should have an automatic or manual device to cut off the gas source in an emergency.


	 


	The gas infrared radiation equipment promoted and sold by Beijing Leadway&nbsp; Power&nbsp;Co., LTD., does not need to install external combustion equipment, independent heaters are usually installed outside the building.At the same time, according to the Code for Fire Prevention of Building Design, the fire risk category of "using gas, liquid and solid as fuel or burning gas and liquid for other purposes" belongs to Class D.And gas infrared radiation equipment system performance is very stable, so the use of gas radiation heating will not increase the risk and design difficulty of buildings.
