Buildings with a space height greater than 5 meters and a volume greater than 10,000 square meters are called tall space buildings.For example, factory buildings, maintenance warehouses, warehouses, stadiums, exhibition halls and other buildings belong to tall space buildings.The structural form of tall space buildings has poor thermal insulation and large heat consumption.In the cold or severe regions in the north, the use of traditional convection heating in winter, such as radiators, heaters are not the best solution.


	 


	The insulation of the wall and roof of the tall space building is usually not very good, more doors and Windows cause cold air penetration is very strong, the use of centralized heating (or build their own boiler heating), the end of the heat fin heating, in the northeast can reach the standard of 5-10 degrees at most, so the heating company even if the output of a lot of heat can not get customer satisfaction.This is determined by the nature of this convection heating method, that is, directly heating the air, caused by a large temperature gradient.The effect of the heater may be better, but the essence is the same to heat the air, through air convection to raise the temperature.Even if the water in the wind tray reaches 30 degrees, the wind blown out in the workshop will make people feel very uncomfortable, the noise of the fan and the dust are insurmountable problems.


	 


	So, how to design the heating system of this kind of tall space building?

	Gas infrared radiation heating is the use of combustible gas, through the special combustion device - generator combustion and radiation of various wavelengths of infrared radiation for heating.Gas radiation heating is a way for heating tall space buildings, especially suitable for intermittent heating buildings, but also suitable for local heating in tall buildings.Its heat is relatively large, and the thermal efficiency is relatively high, the most important is energy saving and environmental protection, it is also very convenient in installation, and the advantages are obvious.


	 


	Short payback period


	Gas infrared radiation heating system is mainly manifested in the initial investment can be saved in a few years through energy savings.


	 


	Uniform temperature distribution


	Under the gas infrared radiation heating system, the temperature peak will not be felt, and the heating is uniform.


	 


	Spatial gain


	The gas infrared radiation heating system is installed on the roof, does not occupy the ground and walls, etc., can make full use of the ground and walls.


	 


	Comfortable and healthy


	Gas infrared radiation heating system heating without blowing, will not cause dust flying, the operation is very quiet.


	 


	IMPRESIND-gas infrared radiation equipment promoted and sold by Beijing Leadway Power Co., LTD., the independent heater is generally installed outside the building.At the same time, according to the Code for Fire Protection of Building Design: "The use of gas, liquid and solid as fuel or the combustion of gas and liquid for other purposes of various production" fire risk category belongs to Class D.And the gas infrared radiation equipment system performance is very stable, therefore, the use of gas radiation heating will not increase the risk and design difficulty of the building.

	IMPRESIND-gas radiation heating system generator burns natural gas, the thermal fluid generated flows in the radiation tube, generates infrared, does not heat the air, directly acts on the heat object (ground, object, human body), small heat loss.The generator burns completely, so that the heat is fully utilized.At the same time, after the heat exchange of the hot fluid inside the radiation tube, part of the product will be used for gas recirculation through the premixing chamber, and heated twice to achieve energy saving and environmental protection and reduce operating costs.Under the premise of establishing the same comfortable conditions, the design temperature of the building during radiation heating can be reduced by 2°C~3°C compared with that during convection heating, which can also save heating energy consumption.
