Description of the hot water radiant panel in the Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings: The ceiling hot water radiation panel is a kind of metal radiation panel, which can be used for comprehensive heating of buildings with a height of 3m~30m and local area or local workplace heating, and its use is very wide, including large shipyards, ships, aircraft and automobile maintenance halls, building materials markets, shopping centers, exhibition venues, multi-functional stadiums and entertainment halls and many other occasions. The water supply temperature of the ceiling hot water radiation panel should be 40℃~95℃ high temperature hot water. The water quality of hot water should meet the requirements of the current national standards.

The ceiling hot water radiation plate belongs to the plane radiator, the scope of the radiation is limited to the half space it faces, the heat of the radiation is proportional to the fourth power of the Kelvin temperature, so the surface temperature of the radiator plays a decisive role in the local heat distribution, affecting the heat distribution of each part in the room. Of course, the installation position and height of the radiation panel also affect the indoor temperature distribution. Therefore, in the heating design, the minimum installation height of the radiant panel and the maximum average temperature of the heat medium in the radiant panel at different installation heights should be limited. 
 

	The layout of hot water radiant panel is very important to optimize the design of heating system and ensure the uniform distribution of irradiance in indoor activity area. Generally, the arrangement of the ceiling radiant panel should be set parallel to the longest outer wall, or perpendicular to the outer wall if necessary. The specifications of the radiant panel row set along the wall should be greater than the specifications of the radiant panel set in the middle of the room, which is because the heat load of the heating system is mainly determined by the heat consumption of the heat transfer of the envelope structure and the heat consumption of the cold air invading or infiltrating through the external door and window. Therefore, in order to ensure the uniform distribution of irradiance in the indoor working area, the different thermal needs of different areas of the indoor space should be considered, such as setting large specifications of radiation panels on the external wall to compensate for the heat loss at the external wall. The structural size of the room also affects the arrangement of the radiation panel of the suspended ceiling. When the height of the room is low, it is appropriate to use a narrower radiation panel to avoid excessive irradiance; When the radiant panel is arranged along the exterior wall and the panel row is long, attention should be paid to the reservation of thermal expansion room in the length direction.

ECOPAN hot water radiation panel promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. is made of metal tube plate, which is prefabricated into 3 meters and 6 meters (special requirements can be prefabricated into 2 meters and 4 meters) standard length. Each radiant panel can be connected with a quick connector. Each radiant panel and collection pipe is prefabricated in the factory and tested for safety. With the same dimensional characteristics (pipe diameter, number and spacing, panel width), ECOPAN hot water radiant panels have higher thermal energy efficiency than other products on the market. This makes it possible to use fewer products to meet the same heating requirements, saving on materials and installation costs. 
 
High efficiency and energy saving 
In the radiant heating environment, the indoor air temperature is 2-3℃ lower than the air temperature in the convective heating system environment, and the energy saving and comfortable environment is also achieved. The building maintenance structure (walls and floors) is directly heated by infrared rays, which is higher than the air temperature, and the air has a temperature difference, forming secondary heat dissipation, and there is a certain heat preservation and energy saving performance. 
 
Uniform heating 
In the ceiling hot water radiant panel heating environment, the heat distribution is uniform, the body feeling is comfortable and soft, and there will be no local temperature uneven phenomenon such as the wind system heating environment. 
 
Safe and reliable 
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. 
 
Low operating cost 
The hot water radiation panel of the suspended ceiling is used as the terminal heat dissipation device, no electromechanical parts, no electricity consumption, saving operating costs.
