Due to the characteristics of tall space buildings, there are a variety of heating methods to choose from. The municipal conditions of radiator heating are easy to meet, but the heating effect cannot be guaranteed.The ground radiant heating system can solve the problem of excessive temperature gradient in high space temperature field, but it needs to build a heat exchange station, and the cost increases significantly.So what kind of way is suitable for tall space buildings, especially in the industrial field, both to meet the heating needs, but also to achieve energy saving, but also to improve human comfort?


	 


	Gas infrared radiation heating is natural gas or liquefied petroleum gas, through a special combustion device - generator combustion and radiation of various wavelengths of infrared heating.Gas radiation heating is a way for heating tall buildings, especially suitable for intermittent heating tall space buildings, and there is no danger of freezing when disabled, unless the process requires, otherwise do not provide heating at on-duty temperature.

	In this way, it basically relies on 100% radiation heating, and convection has no effect on people's thermal sensation, so the human body comfort in the heating area with radiation heating is higher.The realistic temperature of radiant heating is 2 ~ 3℃ higher than that of convective heating, that is to say, in the case of ensuring the same indoor realistic temperature, the indoor air temperature of radiant heating is 2 ~ 3℃ lower than that of convective heating, so the heat consumption is small, and the indoor and outdoor temperature difference is small, so the cold air permeability is also small, so as to save energy.Many practices have proved that gas infrared radiation heating technology can well solve the problem of unreasonable temperature distribution in a large space, theoretically saving energy 30% ~ 50% compared with convective heating, and the economy is very obvious.


	 


	However, due to the high surface temperature of the radiation tube, if the installation height is too low, the radiation intensity felt by the human body will exceed the requirements of human comfort, so the "Civil building heating ventilation and air conditioning design Code" (GB50736-2014) article 5.6.3 stipulates that the installation height of the gas infrared radiator should not be less than 3m.Due to the dependence of gas radiant heating on combustible gas, the design requirements of ventilation and fire protection in building design are higher than those of ordinary buildings, and emergency ventilation should be set up according to regulations, and corresponding combustible gas detection and alarm devices should be made.

	IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power Co., LTD., the heat generator is installed on the side wall or roof of the outside of the building, the system performance is very stable, therefore, the use of gas radiation heating will not increase the risk and design difficulty of the building.And gas radiation heating equipment technology is very mature, gas combustion directly discharged to the outdoor is completely feasible, in line with environmental protection requirements.


	 


	Gas infrared radiation heating technology is very suitable for all kinds of industrial plants, aircraft, railway maintenance warehouses, storage garages and other buildings with tall space.Gas infrared radiation heating system is suitable for high space building without explosive gas, dust place, good economic benefits.For remote places without heat sources but with gas, compared with the new boiler room heating system, gas infrared radiation heating system is a better choice.
