In the north of our country, the winter heating of tall space has always been a difficult problem.At present, traditional convection heating methods such as radiators and hot water heaters are still used, and the initial investment cost is low, but the requirements of heating are also less.High space span, large temperature stratification, using the traditional convection heating method is not good.


	 


	In recent years, radiant heating equipment has begun to be promoted and widely used.For tall space buildings such as factories, warehouses and hangars, gas infrared radiation heating is based on the principle of sunlight and infrared rays. Its biggest advantage is that infrared rays penetrate the air without heating the air, so the temperature distribution is more uniform, the temperature gradient is relatively small, and the ineffective heat loss is less, which can avoid the vertical imbalance of the temperature field generated by convective heating.At the same time, according to the production process requirements, local heating or intermittent heating can be carried out in the plant area, which is not achieved by the flow heating.

	Compared with the traditional convection heating method, gas infrared radiation heating can save 30%-50% of operating costs, and the energy saving effect is very significant.Natural gas and liquefied petroleum gas are clean primary energy sources, and combustion products will not pollute the atmosphere.


	 


	In addition, if the traditional radiator heating can only be operated during the heating season, once the heating is stopped, the pipeline equipment of the water heating system may be frozen and cracked.The radiant heating system can be started and stopped at any time as needed.


	 


	Under the same indoor thermal comfort conditions, the air temperature required for radiant heating rooms can be at least 2 to 3 ° C lower than that for radiator heating.If the radiator is used for heating, the room temperature should reach at least 18 ° C;The use of radiation heating, the room temperature as long as 16 ° C can make people feel comfortable), so you can save a lot of heating energy.

	At present, gas infrared radiation heating can only be used in industrial plants, hangars, logistics warehouses and other class D and E plants.The gas infrared radiation equipment promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. does not need to install external combustion equipment, and independent heaters are 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.
