Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009860
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises: a decompression unit (14, 142); an evaporation unit (15); a decompression control unit (20b); a pressure detection unit (21a); and a temperature detection unit (21b). The pressure detection unit (21a) detects an outlet-side pressure (Pe) of an outlet-side refrigerant of the evaporation unit (15). The temperature detection unit (21b) detects an outlet-side temperature (Te) of the outlet-side refrigerant of the evaporation unit (15), and the decompression control unit (20b) controls operation of the decompression unit (14, 142) by using at least the outlet-side pressure (Pe) as well as a delayed outlet-side temperature (Ted) obtained by subjecting the outlet-side temperature (Te) to delay processing.
