Background
Radiation air conditioning systems have received increasing attention for their potential to improve comfort in the indoor environment and to achieve energy savings in buildings. However, in order to avoid surface condensation in the cooling process of the existing radiation air-conditioning system, the temperature of the radiation cooling surface needs to be strictly controlled to be higher than the dew point temperature of indoor air, and the improvement of the cooling capacity of the system is restricted. Thus, radiant air conditioning systems often only carry part of the sensible heat load, requiring a combined ventilation and dehumidification system to provide cooling and carry the latent heat load. Meanwhile, the existing radiation air-conditioning system carries out undifferentiated radiation cooling indoors, and besides indoor personnel, other indoor unrelated objects such as walls, furniture and the like can be cooled, so that the total cooling load borne by the system is increased to a certain extent, and energy waste is caused.
Chinese patent application No. CN01272630.3, the name of utility model is: the technology discloses an anti-condensation device of a radiation cooling ceiling, wherein one or more layers of isolating layer materials with high transmittance to light waves radiated by indoor objects are arranged on the surface of the ceiling; an enclosed gas or vacuum interlayer is formed between the materials and between the ceiling surfaces that is isolated from the room air.
In the prior art, a radiation air-conditioning system usually performs indiscriminate radiation cooling indoors and does not have the function of directional radiation cooling, and the effective utilization rate of radiation cooling capacity needs to be further improved. Therefore, the anti-condensation directional radiation cooling air-conditioning terminal device avoids condensation of a radiation air-conditioning system, realizes accurate utilization of radiation cold and has important significance for promoting building energy conservation.

And a proper amount of drying agent is added into the closed air layer, so that the closed air layer is always kept in a low-humidity state, and the phenomenon of condensation on the lower surface of the radiation panel is avoided.
