Document Type and Number:
WIPO Patent Application WO/2023/139765
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device equipped with a refrigerant circuit using a compressor, the refrigeration cycle device comprising: a temperature acquisition unit that acquires a value indicating the condensation temperature of refrigerant in the refrigerant circuit and a value indicating the evaporation temperature of the refrigerant; and a lower limit determination unit that determines a lower limit for the operating frequency of the compressor on the basis of the condensation temperature and the evaporation temperature. Thus, compressor vibration can be suppressed.
