"Air Conditioning Design and Engineering Record of Large Space Buildings" believes that: "Buildings with a space height greater than 5m and a volume greater than 10,000 m3 are called large Spaces."In recent years, most of the public buildings under construction or already built are tall space buildings.Tall space buildings in public and civil buildings are mainly theaters, concert halls, great halls, gymnasiums, exhibition halls and other buildings.In terms of industrial buildings, there are mainly industrial workshops, shipbuilding installation, aerospace testing and assembly, and so on.


	 


	The high height of building space and the serious thermal stratification phenomenon have become a widespread physical phenomenon in tall buildings.The height of building space has a great influence on the form and condition of temperature stratification. Practice shows that with the increase of height, temperature stratification becomes more prominent.The heating of tall space buildings is to improve the comfort of the human body, improve the thermal comfort of the overall building environment in large space, and achieve the purpose of saving energy under the premise of meeting the heating requirements.


	 


	At present, the layout of tall space heating pipeline equipment is difficult.Because of the large heating load in the tall space, it is difficult to arrange the radiator when the radiator is used for heating.When floor heating is used, special treatment should be given to foundation heat insulation, ground heat dissipation and load.When using vertical air supply, horizontal air supply and gas radiant heating, it is also necessary to install pipelines and equipment safely and reliably.In response to these problems, hot water infrared radiation heating can meet the various needs of tall space heating.

	Hot water radiation panel in the process of hot water circulation, through the radiation surface of the medium heat into various wavelengths of infrared radiation and irradiation into the heating environment, due to the small absorption of infrared air, most of the infrared is absorbed by buildings, human bodies, equipment and other objects, energy storage, temperature rise, while heating the air around it, so that the ambient temperature rise.


	 


	As a terminal heat dissipation device, the hot water radiation panel does not require electro-mechanical components, consumes no electrical energy, and runs almost maintenance-free, saving operating costs.Compared with traditional convection heating equipment, the initial investment of hot water radiant panel heating system is relatively high, but its energy saving is obvious after operation, and the higher investment part can be compensated by energy saving in a few years.


	 


	Hot water radiant panel heating system for the water system heating, low temperature and pressure, does not increase the fire rating of the building, can be used in volatile and flammable building environment, will not cause the risk of fire and explosion.The ECOPAN hot water radiation panel promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. uses carbon steel radiation panel;The pipeline uses copper pipe;The design service life is generally 30 years.
