With the gradual adjustment of China's energy structure and the rapid development of modern industry, especially the gas industry, as well as the increase of high-rise buildings, it is the inherent demand of construction units to seek development to abandon the traditional and outdated HVAC design habits and adopt gas radiant heating. This is also a wise choice for high-rise space heating in China. 
 
Gas infrared radiation heating method utilizes the combustion of clean energy such as natural gas and liquefied petroleum gas to radiate infrared rays for heating. Just like the principle of solar radiation on the Earth, infrared rays are not absorbed by the atmosphere and directly radiate to the heating objects. The heating objects absorb the infrared rays and convert them into heat energy, thereby achieving the purpose of heating. Judging from the fact that it has been widely adopted by many countries and is used domestically, gas infrared radiation heating is the most economical and effective heating method for large spaces. 
 
According to GB50019-2015 "Design Code for Heating, Ventilation and Air Conditioning in Industrial Buildings": When using infrared radiant heating with gas, the indoor calculated temperature should be 2℃ to 3℃ lower than the indoor air temperature of convective heating. This not only reduces the air stratification and convective effect but also improves the thermal energy utilization rate of the heating system. 
 
IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power Co., Ltd. uses a generator to burn natural gas. The generated hot fluid flows in the radiation tubes made of aluminum alloy steel under the drive of a negative pressure centrifugal fan. It excites infrared rays and directly radiates heat onto the objects and human bodies within the heating area. After the heat exchange in the radiation tubes, some of the products will pass through the premixing chamber and be used for flue gas recirculation, greatly improving the heating efficiency and making full use of energy. The other part will be directly discharged to the outside. Through two heating processes, the purpose of energy conservation and environmental protection and reducing operating costs is achieved. The overall energy saving can reach 30% to 50%. 
 
IMPRESIND gas radiation heating system is highly suitable for various industrial buildings, aircraft maintenance depots, railway and subway repair depots, warehouses and other industrial buildings with large spaces. Compared with the traditional convective heating method, it is more energy-efficient and can significantly reduce the operating costs of enterprises.
