The insulation of the walls and roofs of tall space industrial buildings is usually not very good, more doors and Windows cause strong cold air penetration, the use of central heating (or build their own boiler heating), the end of the heat sink heating, especially in the Northeast can reach the standard of 5-10 degrees. Even the heating company is not satisfied with its customers even though it outputs a lot of heat. This is not the problem of the heating company, the root cause is determined by the nature of this convection heating method, that is, directly heating the air, caused by a large temperature gradient. Traditional convection heating, hot air in the tall space will produce a gradient effect, every 1 meter rise in height, the temperature will rise 1-1.5 degrees, the air is seriously stratified, hot under the cold, the roof heat loss is very large. In contrast, infrared radiation heating does not heat air, only the human body and dense objects, so there is no thermal gradient. Infrared radiation heating can meet human comfort requirements at 3 to 5 ° C lower than the traditional heating air temperature, without heating the entire space air to a higher temperature, such as 18 ° C. 
 
Infrared radiation heating technology features: 
 
1, high thermal efficiency: radiant heat is directly absorbed by the human body, equipment, etc., and converted into heat energy, heat conversion efficiency of more than 90%, improve energy utilization. 
 
2, small heat loss: no strong convection phenomenon, indoor air stratification and thermal gradient phenomenon is weak, small temperature difference, reduce heat loss, and reduce energy consumption by 30%~50%. 
 
3, uniform heat dissipation: the indoor temperature distribution is uniform, reduce the radiation of the human body to the outside world, and avoid the problem of "foot cold head heat" in traditional heating. 
 
4, continuous heat transfer: the heat is concentrated in the height of the human body to benefit, improve the proportion of radiation heat transfer, and the surrounding environment for a long time. 
 
The use of infrared radiation heating system, no need to install a large and complex boiler room, heat exchange station and related heat pipelines, such as gas radiation heating system only need to be connected with the gas pipe network, the initial investment is greatly reduced. The system layout is simple, and the installation is suspended, which does not occupy the use area in the building and saves valuable building land. The system does not need to set up a special post to work or operate. Compared with traditional convective heating, the workload of operation, maintenance, overhaul and maintenance is greatly reduced, and the operation and maintenance cost is reduced. 
 

	In the future, with the advancement of the industrialization process and the renewal of old equipment and the further elimination of regional boilers, the coverage rate of infrared radiation heating equipment is expected to be further improved. The infrared radiation heating method is suitable for comprehensive heating of buildings with a height of 4m~30m and local area or local working place heating. Whether it is a manufacturing enterprise, storage and logistics center or aircraft, railway maintenance warehouse, infrared radiation heating equipment can be perfectly applied.

The independent heating generator of IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power Co., Ltd. is installed on the outside of the building, such as the top or side wall of the building, and the radiation tube is installed above the internal space of the building, which does not occupy the building space. Radiant heat directly radiates downward, the ground can also save part of the heat, gas radiation heating indoor air temperature is 2 ~ 3℃ lower than convective heating, indoor air temperature gradient is small, heat loss is small, cold air permeability is also small, reduce heat consumption under the premise of ensuring comfort, carry out effective energy-saving measures, can ensure the high space industrial plant internal temperature comfort. At the same time, it can also reduce the heating cost and increase the efficiency of enterprises.
