At present, some high-space industrial plants and high-space public buildings have large cold air permeability and large temperature gradient, which require higher indoor temperature and higher comfort. The traditional heating method is difficult to meet these needs, and the gas radiation heating system has the advantages of high efficiency and energy saving, fast thermal effect, uniform heating, and high comfort, which can efficiently solve the needs of tall space heating. Compared with convective heating, gas radiation heating can save 30-50% energy, which is mainly reflected in the following aspects:

1, convective heating, indoor air is heated, and the formation of hot and cold air convection, so the indoor air temperature has a large gradient, the roof part of the temperature is high, close to the ground temperature is low, the general convective heating temperature gradient of about 0.5-1.0℃/m; When the radiant heat is heated, the radiant heat radiates directly down, and the ground part will also accumulate some heat, so the temperature gradient of the indoor air is small, and the heat loss corresponding to the upper part of the building is also small. 
 
2. When the indoor air temperature is the same, radiant heat directly radiates the heating object, and the realistic temperature of radiant heating is 2 ~ 3℃ higher than that of convective heating. That is to say, under the condition 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 temperature difference between indoor and outdoor is small, so the cold air permeability is also small. 
 

	The generator of the gas radiation heating system only needs to be taken over the gas pipe network, and the regulating and stabilizing equipment is installed at the entrance of the system, without the need to install heating boilers and other ancillary equipment. There is no heating water circulation system, which greatly reduces the one-time investment. At the same time, due to the high temperature of the heat medium, the metal consumption of the radiator is low, and the investment is more economical. There is no need for large and complex boiler and boiler room equipment, the system structure is simple, the installation cycle is short, and the use area of the building is not occupied. Radiant installations are usually installed in the upper part of the heating space in a building, so little or no building is occupied, saving valuable building land.

IMPRESIND gas infrared radiation heating equipment, promoted and sold by Beijing Leadway Power Co., LTD., has an independent heater installed on the outside of the building, and the radiation pipe section is placed on the upper part of the heating space, which does not occupy the building space. Radiant heat directly radiates downward, the ground can also store part of the 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. Its control system can realize independent control or centralized remote control. The smart LCD centralized control box can control multiple groups of devices and can be connected to the software of the computer. Automatic control and temperature regulation are convenient and can realize partition control temperature. 
 
The insulation requirements of the maintenance structure of tall space buildings are not very high. Gas radiation heating system can heat tall space, semi-open space, and convection heating can not do. Heat transfer has a strong directional, it can be flexibly arranged according to different needs, it can be a comprehensive heating, but also in a local large space for local heating.
