Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066002
Kind Code:
A1
Abstract:
This refrigeration cycle device (1) comprises a refrigerant circuit (110), a bypass passage (111), a dryness alteration device (112), a temperature detection unit (113), and a control device (100). The refrigerant circuit (110) circulates a refrigerant in order through a compressor (10), a first heat exchanger (20), a first expansion device (50), and a second heat exchanger (60). The bypass passage (111) sends the refrigerant to an intake opening of the compressor (10) from the first heat exchanger (20) without passing through the first expansion device (50) and the second heat exchanger (60). The dryness alteration device (112) is configured so as to alter the dryness of the refrigerant flowing through the bypass passage (111). The temperature detection unit (113) is configured so as to detect an alteration in temperature before and after the dryness is altered by the dryness alteration device (112). The control device (100) controls the dryness alteration device (112). The control device (100) specifies a type for the refrigerant on the basis of the alteration in the temperature detected by the temperature detection unit (113).
