High space industrial plant, large span, large door and window area, trapped structure heat transfer coefficient of large smoke window effect is extremely obvious, doors, Windows and other gaps of cold air penetration consumption of large traditional convection heating, hot air in the tall space will produce gradient effect, height per 1 meter, the temperature will rise 1-1.5 degrees, serious stratification of air, heat under the cold, roof heat loss is very large. 
 

	Infrared radiation heating technology is recommended to solve the heating problem of industrial plants in tall space. Infrared radiation heating method to achieve infrared radiation heat transfer is different from traditional convection heat transfer, it does not directly heat the air, heat radiation waves through the air almost no heat loss, only heating the human body and dense objects, no thermal gradient. As an important way of clean heating, this technology has significant advantages. Its thermal efficiency is high, radiant heat is directly absorbed by the human body and equipment, and the conversion efficiency is over 90%, effectively improving the energy utilization rate. At the same time, the heat loss is small, no strong convection phenomenon, small temperature difference, reduce energy consumption. Heat dissipation is uniform, avoiding the problem of "cold feet and hot heads", and the heat is concentrated at the height of the human body.&nbsp;

According to the heating code for industrial buildings, the calculated temperature of the infrared radiation heating room should be slightly lower than 2-3 ° C for convective heating to meet the human comfort requirements, without heating the entire space air to a higher temperature, such as 18 ° C. In this way, the heat load is lower, the comfort is higher, and the energy saving effect is remarkable. Therefore, infrared radiation heating technology is an ideal choice for high-efficiency and environmentally friendly heating of industrial plants in large Spaces. 
 
IMPRESIND gas radiant heating system promoted and sold by Beijing Leadway Power Co., Ltd. is an independent heating system, with an independent heating generator, which can be 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, and does not occupy the indoor ground space. The generator adopts double fan, micro positive pressure and negative pressure system design, and double wind pressure difference switch configuration. The micro positive pressure fan can ensure the stability of the flame without flame spillover, and the negative pressure fan can well elongate the flame in the radiation tube to ensure the combustion efficiency. 
 
The generated hot fluid flows in the radiation tube under the drive of the smoke exhaust fan (vacuum pump), and the high temperature surface of the radiation tube excitates the far infrared radiation wave. After the heat exchange of the hot fluid inside the radiation tube, part of the product will be recycled through the premix chamber, and the other part will be discharged by the smoke exhaust fan. Secondary heating to achieve energy saving, environmental protection, high efficiency, reduce operating costs. IMPRESIND gas radiation heating system is a green and environmentally friendly heating product, very suitable for all kinds of industrial plants, aircraft, railway maintenance warehouses, storage garages and other tall space industrial plant heating.
