"Air Conditioning Design and Engineering Record of Large Space Buildings" believes that: "Buildings with a space height greater than 5m and a volume greater than 10,000 m3 are called large Spaces", such as large industrial plants, maintenance warehouses, warehouses, large exhibition centers, stadiums and other places.This place has the characteristics of large area, large span and high storey.In the heating design, how to achieve on-demand heating, effectively reduce temperature stratification, avoid ineffective heat loss, and achieve energy saving and emission reduction in tall space industrial plants is a problem faced by many designers.


	 


	In recent years, with the introduction of heating equipment and technology from Europe and the United States and other countries or regions, there are more ways to take, such as gas radiant heating system, which can fully meet the heating needs of the growing tall space buildings.According to GB50019-2015 Design Code for Heating, Ventilation and air conditioning of industrial buildings 5.5.4: When gas infrared radiation heating is used, the calculated indoor temperature should be 2℃ ~ 3℃ lower than the air temperature in the convective heating room.Under the premise of achieving the same heating effect, the heat load is lower, the comfort is higher, and the energy saving is more.

	IMPRESIND gas radiant heating system is the main heating equipment of Beijing Leadway Power Co., LTD. It is composed of 3 major components, including heat generator, radiation pipe section and control system.The gas radiant heating system realizes the heating without open fire and the operation of completely safe opening and closing and negative pressure, which provides a reliable guarantee for the safe operation of the heating system.


	 


	The heat generator is installed on the outside of the building, such as the roof, side walls and other locations, and does not occupy the internal space of the building.The generator performance is stable, so the gas radiation heating system is used in tall Spaces, which will not increase the fire danger level and design difficulty of the building.


	 


	The radiation pipe section is installed under the roof frame of the workshop and above the car, about 5-30m from the ground, which does not occupy the use area of the workshop and does not affect the process operation of the workshop.The radiation pipe section can be arranged according to the location of the working area in the building, which can effectively improve the utilization rate of the heating equipment and form a uniform temperature distribution in the heating space.

	The gas radiant heating system can intelligently change the operating state according to the temperature change, and the energy and operating costs are significantly reduced.Can be set at any time, any temperature of any device.It has the function of automatically opening and closing on time, and automatically runs according to the set temperature without manual adjustment.
