Tall space buildings have the characteristics of large space area, high height and relatively small personnel activity area.Due to the rise of hot air generated by the traditional convection heating method, a large amount of heat is consumed in the upper part of the tall building, and the lower working area is difficult to obtain enough heat, and the temperature distribution is uneven.This not only causes a waste of energy, but also poor thermal comfort, which has been proved unsuitable for tall space buildings.Gas radiant heating solves this problem well.


	 


	Gas radiation heating is the use of natural gas, gas liquefied gas, burning in a special combustion device - heating generator and radiation of various wavelengths of infrared heating.After the infrared ray is irradiated to the object, some of it is absorbed and some of it is reflected, and the object and the human body are heated twice.

	Gas radiant heating reduces a large amount of ineffective heating, and the thermal efficiency is greatly improved, so it is especially suitable for the heating of tall space industrial plants.Compared with the traditional convection heating method, a heating period can save energy up to 30%-50%, mainly reflected in the following four aspects:


	 


	1, because the radiant heat directly irradiates the heating object, almost does not heat the air in the environment, so the indoor temperature gradient of the radiant heating is small, compared with convective heating, in the case of the same indoor air temperature, the realistic temperature of the radiant heating pen is 2-3℃ higher than the realistic temperature of the convective heating.In other words, in the case of ensuring the same indoor realistic temperature, the indoor air temperature of radiation heating is 2-3 ° C lower than that of convective heating, so the temperature difference between indoor and outdoor is small, so the cold air permeability is also small.


	 


	2, due to the convection heating, indoor air is heated, and the formation of hot and cold air convection, so the indoor air temperature has a large gradient, the roof part of the temperature is high, the temperature near the ground is low, and radiant heating, radiant heat directly downward radiation, the ground part can also save some heat, so the indoor air temperature gradient is small, the corresponding tall space building above the heat loss is small.


	 


	3, there is no loss of gas in the transmission process, and the combustion of the heating generator is very complete, so the heat of the entire heating system can be fully utilized.The traditional radiator heating system, after the heat source from the boiler, there is a heat loss of 10%-15% along the way, so the thermal efficiency is low.


	 


	4, low power consumption, gas radiation heating power consumption is negligible.The sending and returning fans in the hot air system are large power consumers.
