Description

technical field [0001] The invention relates to the technical field of indoor ventilation and air conditioning, in particular to a capillary network radiation heat exchange ceiling board and a ceiling pavement structure thereof. Background technique [0002] Since German scientists invented the capillary radiant air-conditioning system based on the principle of bionics in the 1970s, although it has been neglected for most of the time, as the global energy cost is getting higher and higher, environmental pollution and the greenhouse effect are intensifying, governments of all countries are working on it. Improving the standards for energy saving and emission reduction has made capillary radiant heating and cooling technology a hot spot in research and development in the industry in recent years. [0003] The radiant ceiling panel is an air-conditioning terminal product that uses capillary radiation heating and cooling technology. It mainly lays a capillary network on a heat-c...

AI Technical Summary

Problems solved by technology

In winter, due to the limitation of the heat conduction efficiency between the capillary network in the radiant ceiling and the heat conduction material plate, the heating temperature should not be too high, generally 25~35°C, otherwise the heat energy of the heat exchange medium with too high temperature will not be able to effectively pass through the heat conduction The material board radiates outwards, which causes a large amount of heat energy to accumulate in the radiant board, which easily accelerates the aging of internal devices, shortens the service life, and reduces comfort and increases energy consumption; in summer, not only the limitation of heat conduction efficiency affects the radiant ceiling board At the same time, the cooling temperature should not be too low, generally 18~20°C. If the cooling temperature is too low, condensation will accumulate on the radiant ceiling and drip into the room, which will affect the indoor hygienic conditions. Limits the cooling and heat transfer capacity of radiant ceiling panels per unit area

Therefore, the lack of heating and cooling capacity makes it difficult for radiant ceiling panel technology to meet the needs of large heating and cooling loads, which greatly limits the promotion and application of radiant panel systems in more regions and fields
