Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/193967
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device with which the cost can be reduced by using a sensor capable of measuring the temperature of a plurality of refrigerant pipes in a noncontact manner at one time. A refrigeration cycle device (100) is provided with a refrigerant circuit (102) in which a compressor (11), a heat-source-side heat exchanger (13), an expansion mechanism (15), and a usage-side heat exchanger (22) are connected in sequence. The refrigeration cycle device (100) is provided with a temperature detection unit (17) for detecting the temperature at a plurality of sites in a noncontact manner, and a heat-source-side control unit (19). The heat-source-side heat exchanger (13) and/or the usage-side heat exchanger (22) has a plurality of refrigerant pipes (13b) in the interior of which flows a refrigerant that is to undergo a heat exchange, and a flow volume adjustment unit (13c). The flow volume adjustment unit (13c) adjusts the flow volume of the refrigerant flowing in each of the plurality of refrigerant pipes (13b). The temperature detection unit (17) detects the temperature of each of the plurality of refrigerant pipes (13b). The heat-source-side control unit (19) controls the flow volume adjustment unit (13c) on the basis of the temperature detected by the temperature detection unit (17).
