Radiant cooling and heating is primarily the use of thermal radiation, which is the way an object itself has temperature to radiate electromagnetic waves to transfer energy, to transfer cold and heat. The suspended ceiling radiation is characterized in that a radiation plate is arranged in a suspended ceiling of a room, a refrigerant or a heating medium is introduced into the radiation plate, and the radiation plate exchanges heat with other surfaces of indoor enclosing structures, furniture, human bodies and the like in a convection mode and a radiation mode to achieve the purpose of heating or cooling, and the suspended ceiling radiation has the advantages of energy conservation, peak energy consumption reduction, high thermal comfort, no blowing sense and the like.
The cold/heat medium coil of the existing radiation plate is connected with the radiation plate by heat conducting glue or a cutting sleeve, so that the load reaction time is short, and the installation and the maintenance are convenient. But the heat transfer resistance between the cold/heat medium coil and the radiation plate is larger, so that the cold/heat supply amount is lower, and the heat exchanger can only be used in places with smaller load; and the heat transfer capacity of the direct contact position and the indirect contact position of the cold/heat medium pipe and the radiation plate are different, so that the temperature distribution of the plate surface is uneven, and the heat exchange efficiency is poor.
