At present, if the traditional heating system is used in some big space buildings, there are many problems, mainly the temperature distribution is not uniform, and the vertical temperature gradient is larger.The use of gas infrared radiation heating technology can completely solve the above problems.


	 


	The composition and basic 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.


	 


	The basic principle is: the gas infrared radiation heating system is driven by a fan or a vacuum pump, so that 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 technology 


	 


	1. High safety: 


	When the system is in normal operation, the flow ratio of gas and air is basically constant. Only in the state of negative pressure can the gas flow in the pipeline, so as to avoid the problem of gas leakage.In addition, with gas leakage automatic control system and alarm system, the operation of the system is monitored at any time.


	 


	2. Experience comfort: 


	Gas infrared radiation heating technology has high radiation intensity and good effect, reducing the cold radiation of the surface of the enclosure structure to the human body. At this time, the human sense of temperature is higher than the ambient air temperature, so the human body has better comfort.


	 


	3. high efficiency and energy saving: 


	Gas infrared radiation heating technology because of the radiation area is large and uniform, heat transfer loss is reduced correspondingly, the system energy-saving effect is remarkable.At the same time, the radiator burns very completely, so that the heat of the entire heating system can be fully utilized.


	 


	4. environmental protection and simple installation: 


	 


	Gas infrared radiation heating system gas source for natural gas and other clean energy, combustion products without sulfide, no dust to achieve environmental protection requirements.Compared with the traditional radiator heating system in installation, there is no need to arrange the radiator and supporting pipes in the room, so it does not occupy the building area, simple and convenient installation.


	 


	Example of application of gas infrared radiation heating technology -- Daxing New Airport hangar Project of China Southern Airlines 


	 


	Project Overview: 


	Hangar No.1 of Beijing New Airport Southern Hangar covers a total area of 39,000 square meters, equivalent to 5 football fields or 80 basketball courts. It consists of a maintenance hangar hall and four floors of attached buildings. Hangar No.1 has a total of 5 wide-body and 3 narrow-body hangars, which can accommodate 12 aircraft including 2 Airbus A380 and 3 Boeing 777.Flexible parking can meet the needs of multiple aircraft types and different maintenance requirements.This project is a large single unit project in the Southern Airport Base of Beijing New Airport. After completion, it will become the largest aircraft maintenance hangar in Asia and the largest single maintenance hangar with a large span in the world.(Excerpt from News Bulletin of China Southern Airlines Official Website)

	Features of the project: 


	1. The building span of the maintenance hangar is large and the maintenance hangar is high.


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


	3. The temperature gradient in the building is large, and the air stratification is more serious, leading to the upper heat and the lower cold, so that the roof heat dissipation is faster.


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


	5. The door of the building is frequently opened, and the cold air incurs great heat consumption.


	6. The maintenance hangar is mainly used for aircraft maintenance, so it has high safety requirements.

	Eighty-four IMPRESIND (Ipside) infrared gas radiant heating Tuba-One series products have been selected by Beijing Leadway Power Co., LTD.The product provides an efficient and economical heating solution for the hangar of Daxing new Airport of China Southern Airlines, and is currently running well.


	 


	Gas infrared radiation heating technology is a new type of heating system with high safety, high efficiency, energy saving and comfortable experience, which is conducive to energy saving and environmental protection, and simple installation.It can be inferred from the good application effect of Daxing new airport hangar project of China Southern Airlines that the gas infrared radiation heating technology should have broad application and development prospect in the heating field of tall space buildings.
