For the heating of tall space buildings, the traditional convection heating method not only consumes energy, but also is difficult to solve the heating problem of tall space and other occasions, or the heating effect can not meet the ideal requirements.So, what kind of heating equipment should be selected for tall space buildings, both efficient and economical?


	 


	Infrared radiation heating is especially suitable for tall space, large air exchange, local heating, gap heating and other tall space places, and its economy is very significant.It is used in a wide range of places, including large shipyards, repair halls for ships, aircraft and automobiles, building materials markets, shopping malls, exhibition halls, multifunctional sports halls and entertainment halls, among others.


	 


	Practice has proved that compared with traditional water heating (natural convection heating) and air heaters (forced convection heating), infrared radiation heating has certain advantages in terms of technology and economy.

	Compared with traditional convective heating, infrared radiation heating has a lower heat loss in tall space buildings, mainly for three reasons:


	 


	1、Because of radiation heating, radiation heat directly irradiates the heating object, almost does not heat the air in the environment, so the air temperature of radiation heating is lower than the air temperature of convective heating under the same health conditions, generally 2-30C is lower, so the indoor and outdoor temperature difference is small, so the building heat loss is smaller.


	 


	2、because the temperature difference between indoor and outdoor radiation heating is small, so the cold air permeability is small.


	 


	3、due to convective heating, indoor air is heated, and the formation of hot and cold air convection, so the indoor air temperature has a larger gradient, the roof part of the temperature is high, the temperature near the ground is low, the general convective heating temperature gradient is about 0.5-1.0oC/ m, and radiation heating, radiation heat directly down radiation, the ground part can also save some heat,Therefore, the indoor air temperature gradient is small, which can greatly reduce the heat loss of the upper part of the building.


	 


	At the same time, infrared radiation heating, thermal radiation temperature is higher, the human body and equipment receive more radiation heat, temperature rise faster, thermal comfort is strong, so it is recommended to use in tall space buildings.Because the infrared radiation heating directly acts on the equipment or the human body, there is no need to heat the air first, can be in the stadium orientation heating or local heating;Can also do intermittent heating, people boot, no stop.Under the premise of following the law of conservation of energy, infrared radiation heating mainly relies on time-sharing control, regional control to achieve the purpose of energy saving.
