In the cold winter in the north of our country, the indoor and outdoor temperatures are huge.The heating of tall space is gradually concerned and valued by people.Especially in the industrial field, the industrial field of energy consumption accounts for about two-thirds of the whole society's energy consumption, is the key area of energy conservation and carbon reduction.Therefore, the high space heating system should simultaneously take into account the requirements of energy saving, and the heating system should simultaneously meet the two requirements of high space heating and low energy consumption.


	 


	At present, convective heating system is widely used in industrial plants in China.The cooling equipment heats the air in the surrounding environment, and then uses the specific gravity characteristics of hot and cold air to exchange heat, so as to achieve the purpose of improving the entire ambient temperature.However, the heating effect of this way is affected by the spatial form of the building structure, insulation performance and other parameters, and the heating heat load is relatively unstable.


	 


	In some high-end industrial plants, the requirements for heating conditions are high, and the airflow speed caused by heating should not be too large.In the convective heating process, cold and hot air has been circulating, which will affect the comfort of the human body, in contrast, radiation heating basically does not cause air flow, and the heat loss is small, and the building envelope can only absorb heat from the indoor air and dissipate heat to the outdoor through its surface.

	Hot water radiant panel is a kind of metal radiant panel, which can be used for comprehensive heating of buildings with a height of 3m~30m and local area or local working place heating, which is not only efficient and energy-saving, but also has the characteristics of green environmental protection, space saving and high comfort, and its use is very wide.Including large shipyards, maintenance halls for ships, aircraft and automobiles, building materials markets, shopping malls, exhibition halls, multi-functional stadiums and entertainment halls and many other occasions.


	 


	In the process of hot water radiant panel radiant heating, radiant heat directly irradiates the heating object, and rarely needs to heat the gas in the environment, so the air temperature of radiant heating under the same conditions is very low, usually 2-3 ° C, so the temperature difference between indoor and outdoor is small, so the heat loss of the building is relatively low.The heat consumed by radiant heating is relatively low compared with convective heating, which is about 0.8 times that of convective heating, that is, the heat consumption of radiant heating is about 30% of that of convective heating.Radiant heating can save 30-50% more energy than convection heating.


	 


	At present, most people still lack understanding of the technology of the suspended ceiling hot water radiation panel, in fact, the initial installation fee of the suspended ceiling hot water radiation panel is not higher than the current traditional heating costs, especially to the later operation, its energy-saving characteristics mean that energy consumption and economic costs are saved.Hot water radiation panel does not require any special maintenance, no moving mechanical parts, no need to set up a special post to manage and maintain, you can save some labor costs.


	 


	ECOPAN hot water radiation board promoted and sold by Beijing Leadway Power Co., Ltd. adopts innovative design concept, the main features of ECOPAN are: The radiation board is made of metal plate, on the shell of the steel plate, with a diameter of 1/2 "or 3/4" welded or non-welded steel pipe wrapped 2/3 of its surface.As the warmest part of the panel, the pipe is completely downward, and 70% of its surface is wrapped by the metal plate (the wrapping Angle is more than 280°), which increases the heat transfer area, and perfectly ensures the transfer of heat from the tube to the plate, reducing the convective flow and increasing the radiation.

	ECOPAN hot water radiant panel, because it is based on the principle of natural solar radiation, is the most effective heating system, high heat exchange efficiency, small temperature gradient, uniform heat and cold, energy saving 30%~50% than conventional floor heating and convective heating.In addition, due to the low thermal inertia of the ceiling radiant panels, the heating system can only be operated intermittently when necessary, and no other heating system can provide the same comfort at such a low administrative cost.
