Title:
FRESH AIR UNIT, AIR-CONDITIONING SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/066520
Kind Code:
A1
Abstract:
Provided in the present disclosure are a fresh air unit, an air-conditioning system and a control method therefor. The fresh air unit comprises a housing, an indirect evaporative cooler, a water receiving pan and surface coolers, wherein each surface cooler is obliquely arranged in the housing, a lower end of the surface cooler is arranged on the water receiving pan, and an upper end of the surface cooler is arranged on the housing in a sealed manner. According to the fresh air unit, the air-conditioning system and the control method therefor, which are provided in the present disclosure, the indirect evaporative cooler is used for fresh air and return air to carry out one time of heat transfer, and the fresh air is cooled by means of the indirect evaporative cooler and does not come into contact with condensate water, such that the requirements of dehumidification and cooling at the surface coolers are relatively small, thereby reducing the requirements of heat transfer and dehumidification for the surface coolers. In addition, the surface coolers are obliquely arranged, such that the heat transfer area of the surface coolers is increased, thereby improving a heat transfer effect of the surface coolers, thus improving the heat transfer efficiency of the fresh air unit.
