Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/195663
Kind Code:
A1
Abstract:
The refrigeration cycle device (10) according to the present disclosure comprises: a compressor (1); a first heat exchanger (2); a second heat exchanger (4); a decompression device (3); a circulation path for circulating refrigerant in the order of the compressor, the first heat exchanger, the decompression device, and the second heat exchanger; a control device (7) that controls the compressor; and a pressure sensor (6) that is disposed on the suction side of the compressor and detects the pressure in the circulation path. The decompression device is configured so as to be capable of switching the circulation path between an open state and a closed state. The control device starts the compressor when the decompression device switches the circulation path from the closed state to the open state and the pressure increase rate identified on the basis of the detection value of the pressure sensor is less than a threshold value.
