The heating of tall space buildings is to improve the comfort of human body, improve the thermal comfort of the whole building environment in large space and achieve the purpose of energy saving under the premise of meeting the heating requirements.


	 


	At present, the design of the heating system of the public buildings with large space is facing many new challenges.The heating design scheme should not only meet the use requirements, safety requirements, but also take into account the operation of energy saving, so the key points must be clear and optimized in the design.The use of gas infrared radiation heating technology can completely solve many problems.


	 


	Principle of gas infrared radiation heating system 


	 


	Gas infrared radiant heating system can be composed of one or more independent systems, each independent system is composed of burner, radiation pipeline and temperature controller.With the help of negative pressure centrifugal fan, the hot fluid flows in the radiation pipeline of the system, and the exhaust gas is discharged to the outside.The radiation pipe and the reflector above it radiate heat into the space below.When infrared rays touch people and objects, their energy is absorbed by the surface and becomes hot.The heated surface's own secondary radiation heats up the nearby air, releasing heat into the working space.


	 


	The advantages of gas infrared radiation heating system 


	 


	1. Save investment and energy: 


	There is no need to install external combustion equipment. Independent heaters are usually installed outside the building, and radiation tubes are installed above the building space, so that the building does not take up space.Radiant heat directly radiates downward, the ground can also save some heat, indoor air temperature gradient is small, small heat loss, reduce heat consumption under the premise of ensuring comfort, to achieve the purpose of energy saving.


	 


	2. stable performance, safe and reliable 


	According to the Code for Fire Protection of Building Design, the fire risk category of "all kinds of production using gas, liquid and solid as fuel or burning gas and liquid for other purposes" belongs to Class D.And the heat energy generator is set outside the building, the system performance is very stable, so the use of gas radiation heating will not increase the risk and design difficulty of the building.


	 


	3. clean energy, harmless combustion: 


	Clean energy such as natural gas and liquefied petroleum gas is used for heat.At present, gas radiation heating equipment technology is very mature, it is completely feasible to discharge gas directly into the outdoor after combustion, in line with the requirements of environmental protection.


	 


	4. static heating, uniform temperature rise: 


	Quiet operation, no convective air, avoid the phenomenon of ash in the industrial plant, can improve the health conditions of the heating space.Indoor heating speed is fast, heat distribution is uniform, body feeling is comfortable and soft.In addition, considering the poor sealing of many factory Windows, the indoor air temperature of gas radiant heating is 2 ~ 3℃ lower than that of convective heating, and the heat consumption is small, and the indoor and outdoor temperature difference is small, so the cold air permeability is also small.


	 


	5. intelligent temperature control, convenient management: 


	Can realize independent control or centralized remote control, according to the time respectively set the economic mode, night anti-freezing mode and holiday mode, can also be partial intermittent heating, and can set the temperature to run by itself, to achieve a week of unattended, low operation and maintenance cost.

	Application example of gas infrared radiation heating technology&nbsp; 


	-- Harbin Air Mail Processing Center of China Post 


	 


	Project Overview: 


	The total land area of the project is 135,000 square meters, the available area is 120,000 square meters, the total construction area is 100,000 square meters, and the total investment is 650 million yuan. The functions of the project include cross-border e-commerce warehousing, domestic standard express and international standard express processing. The production area includes many functions, such as receiving and mailing, sorting, customs inspection and customs waiting for shipment.


	 


	Features of the project: 


	1. Large area of doors and Windows, large heat transfer coefficient of enclosure structure.


	2. The temperature gradient in the building is large, and the air stratification is more serious, leading to the upper heat and the lower cold, which leads to the faster heat dissipation of the roof.


	3. the building is tall, and the temperature requirements are higher, so the need for faster heating speed.


	4. Due to transportation, the door of the processing center needs to be opened frequently, and the cold air incurs great heat consumption.


	5. the outer wall of the tall space and the floor area is relatively large, leading to the external interface on the indoor space of the natural convection influence is larger, easy to cause cold air around in winter.


	 


	The project uses 34 IMPRESIND (Ipside) infrared gas radiant heating TUB-ONE series products produced by Beijing Leadway Power Co., LTD., fully embodies the advantages of high-power gas radiant heat
