Title:
INDIRECT EVAPORATIVE COOLING DEVICE HAVING FUNCTION OF HEAT RECOVERY, AND HEAT RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2023/142980
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of air conditioners. Provided in some embodiments of the present disclosure are an indirect evaporative cooling device having a function of heat recovery, and a heat recovery method. The device comprises a compressor, wherein an outlet end of the compressor is connected to a first port of a four-way valve; a second port of the four-way valve comprises two branches, a first branch being connected to an air exhaust heat exchanger, the air exhaust heat exchanger being connected to a fourth port of the four-way valve, a second branch being connected to an air supply heat exchanger, and the air supply heat exchanger being connected to an inlet end of the compressor; a third port of the four-way valve is connected to the inlet end of the compressor; the opening and closing states of the first port, the second port, the third port and the fourth port of the four-way valve can be respectively adjusted to enable the device to operate in different heat recovery modes; and a heat recovery assembly is provided on a pipeline between the compressor and the first port, and is used for recovering waste heat of a refrigerant outputted from the compressor in different heat recovery modes. By means of the device and the method of some embodiments of the present disclosure, waste heat can not only be recovered, but the structure is also simple, the space occupation is small, and the apparatus cost is low, such that the problems of a complex structure, large space occupation, and high apparatus cost in the related art are solved.
