INDIRECT EVAPORATIVE COOLING DEVICE HAVING FUNCTION OF HEAT RECOVERY
Document Type and Number:
WIPO Patent Application WO/2023/142979
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of air conditioners. Provided in the embodiments of the present disclosure is an indirect evaporative cooling device having a function of heat recovery. The device comprises a compressor, wherein an outlet end of the compressor comprises a first branch, a second branch and a third branch; the first branch is connected to a first port of a first four-way valve; a fourth port is connected to an outdoor air exhaust heat exchanger; the outdoor air exhaust heat exchanger is connected to an indoor air supply heat exchanger; a third port is connected to an inlet end of the compressor; the second branch is connected to the third port of a second four-way valve; the fourth port is connected to the indoor air supply heat exchanger; the first port is connected to the inlet end of the compressor; the third branch is connected to a heat recovery assembly; the heat recovery assembly is connected to a pipeline between the indoor air supply heat exchanger and the outdoor air exhaust heat exchanger; and the first four-way valve and/or the second four-way valve are/is adjusted to enable the device to operate in different heat recovery modes, such that the air supply heat exchanger can be switched into a condenser mode, so as to realize the reheating of supply air, and thus the problem of water condensation caused by over-low air supply temperature of a machine room in winter in the prior art is solved.
