According to statistics, people have 80% of the time in the indoor, industrialized countries 90% of the time is spent in the building, it can be seen that the advantages and disadvantages of the indoor environment to a large extent affect people's normal work and life. Especially in winter, the comfort requirements for indoor temperature are higher. The traditional convection heating method, due to the rise of hot air, makes a large amount of heat consumed in the upper part of the tall space building, the lower working area is difficult to obtain enough heat, and the temperature distribution is uneven, which not only causes the waste of energy, but also the thermal comfort is poor, has been proved to be a heating method not suitable for tall space buildings. At present, according to the different nature of the use of tall space buildings, the heating of tall space can choose to use radiation heating. 
 

	In the case of radiation heating, the heat loss of tall space buildings is lower than that of convective heating, mainly because: (1) Since radiant heating directly irradiates the heating object and hardly heats the air in the environment, the air temperature of radiant heating is lower than that of convective heating under the same health conditions, which can generally be 2-5 ° C lower, so the temperature difference between indoor and outdoor is small, so the cold air permeability is also small. (2) Due to convective heating, indoor air is heated, and the convection of hot and cold air is formed, so the indoor air temperature has a large gradient, the roof part of the temperature is high, the temperature near the ground is low, the general convective heating temperature gradient is about 0.5-1.0℃/ meter, and radiant heating, radiant heat directly radiates downward, the ground part can also save some heat. Therefore, the indoor air temperature gradient is small, and the corresponding heat loss in the upper part of the building is also small. (3) The heat of the gas heating system can be fully utilized, while the traditional radiator heating system, after the heat source is drawn from the boiler, there is a heat loss of 10-15% along the way, so the thermal efficiency is low.

In the radiation heating method, gas radiation heating radiation heating system with gas as energy saving energy can reach 30-50%, which can greatly reduce operating costs. The gas radiation heating system runs quietly, does not produce convective air, avoids the ash phenomenon in the industrial plant, and can improve the health conditions of the heating space. The indoor heating speed is fast, the heat distribution is uniform, and the body feeling is comfortable and soft. 
 

	IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. is an independent heating system, which uses natural gas to burn in the generator to produce high temperature flue gas, and the generated flue gas flows in the negative pressure radiation tube, so that the surface temperature of the radiation tube rises by 260-280 ° C, and the high temperature surface of the radiation tube generates infrared radiation waves to heat indoor objects. At the same time, after the heat exchange of the hot fluid inside the radiation tube, a part of the product is used for flue gas recirculation through the premix chamber for secondary heating, making full use of energy, and greatly improving the heating efficiency.

In the environment of infrared radiation heating, the upper indoor temperature is low, and the bottom working environment is warm. The human body has a high sense of comfort, and the realistic temperature felt by the human body is 2℃~3℃ higher than the actual indoor ambient temperature, that is, under the premise of the same comfort, the air temperature of radiation heating is 2℃~3℃ lower than the air temperature of convective heating. Gas radiation heating system has no effect on the indoor air composition when working, is a green and environmentally friendly heating product, very suitable for all kinds of industrial plants, aircraft, railway maintenance warehouses, storage garages and other buildings with tall space.
