Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/180821
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) comprises: a first refrigerant circuit (RC1); a second refrigerant circuit (RC2); a heat exchanger (30) that performs heat exchange between a first refrigerant of a condenser (12) of the first refrigerant circuit (RC1) and a second refrigerant of an evaporator (23) of the second refrigerant circuit (RC2); and a control device 40. The control device (40) stops operation of the second refrigerant circuit (RC2) in response to the evaporation temperature of the first refrigerant and an operation frequency value of a compressor (10) of the first refrigerant circuit (RC1) being within a first range. The first range includes a lower limit value for the evaporation temperature and a lower limit value for the operation frequency.
