The anti-condensation radiation cooling device solve the problem of condensation of a traditional radiation cooling system, switching between the global radiation cooling mode and the directional radiation cooling mode can be achieved, invalid radiation coolingis reduced, accurate utilization of radiation cooling capacity is achieved, and energy-saving significance is achieved.

Description

technical field [0001] The invention relates to a terminal device of a radiation cooling system, in particular to a multi-working mode anti-condensation radiation cooling device. Background technique [0002] The radiant air conditioning system has been paid more and more attention due to its potential to improve the comfort of the indoor environment and realize the energy saving of buildings. However, the traditional radiant air conditioning system is limited by the problem of anti-condensation during cooling, and it is necessary to strictly control the temperature of the radiant cooling surface to be higher than the dew point temperature of the indoor air, which restricts the improvement of the cooling capacity of the system. At the same time, the traditional radiant air-conditioning system provides indiscriminate radiative cooling to the room. In addition to the indoor personnel, other irrelevant objects in the room such as walls and furniture will also be cooled, which i...

Problems solved by technology

[0004] Existing radiant cooling devices often only have the function of global radiant cooling or directional radiant cooling, the cooling mode is single, and it is impossible to continuously adjust the concentration or dispersion of radiant cooling, and the anti-condensation requirements restrict Improvement of cooling capacity per unit area of ​​radiant cooling device

Although some technologies have proposed to use an air layer or a vacuum layer to separate the radiant cooling surface from the humid air in the room to avoid condensation, it has not further considered that the low temperature cold radiation of the radiant cooling surface may reduce the temperature of the non-cooled surface below the indoor dew point possible, there is still a certain risk of condensation
