Tall space, as the name suggests, is a building space with higher floors and larger space.From the perspective of HVAC design, the heating problem of tall space has always been criticized.For large space heating, the traditional convection heating method consumes a lot of energy, and it is difficult to meet the indoor temperature requirements of large space.So, is there a heating method that can not only save energy, but also efficiently achieve the heating needs of tall space heating areas?


	 


	Practice has proved that in the space heating of tall space buildings, infrared radiation heating has certain advantages in technology and economy compared with traditional water heating and steam heating (natural convection heating) and air heater (forced convection heating).Compared with the traditional convective heating method, the infrared radiation heating used in tall space buildings has lower heat loss, faster temperature rise and stronger thermal comfort, mainly for three reasons:


	 


	1, because the radiation heating, radiant 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 can be lower by 2-30C, so the indoor and outdoor temperature difference is small, so the building heat loss is also small.


	 


	2, due to the small temperature difference between indoor and outdoor radiation heating, the cold air permeability is also 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 large 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, radiant heat directly downward radiation, the ground part can also save some heat,Therefore, the indoor air temperature gradient is small, which can greatly reduce the heat loss in the upper part of the house.

	Therefore, infrared radiation heating is especially suitable for tall space, large ventilation, local heating, gap heating and other tall space places, and its economy is very significant.Its use is very wide, including factory buildings, large shipyards, ships, aircraft, railway and automobile maintenance halls and many other occasions.


	 


	The gas infrared radiation equipment promoted and sold by Beijing Leadway Power&nbsp;Co., LTD., the independent heater is installed outside the building, and does not occupy the internal space of the building.Radiant heat directly radiates downward, the ground can also store part of the heat, indoor air temperature gradient is small, small heat loss, reduce heat consumption under the premise of ensuring comfort, to achieve the purpose of energy saving.


	 


	According to the Code for Fire Protection of Building Design: "The use of gas, liquid, solid as fuel or the combustion of gas, liquid for other purposes of various production" fire risk category belongs to Class D.And the heat generator is set up outside the building, the system performance is very stable, therefore, the use of gas radiation heating will not increase the risk and design difficulty of the building.
