Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/196045
Kind Code:
A1
Abstract:
A warming operation lower limit refrigerant volumetric flow value, which is the lower limit value for the volumetric flow during a warming operation, is set for a compressor (1), and the rotational frequency of the compressor (1) is controlled so as to achieve a value equal to or greater than the warming operation lower limit refrigerant volumetric flow value. The warming operation lower limit refrigerant volumetric flow value includes a first lower limit value, which is set when a R410A refrigerant is used, and a second lower limit value, which is larger than the first lower limit value and is set when a R32 refrigerant is used in a refrigeration cycle device (100) compatible with the R410A refrigerant. When a warming operation in which the R32 refrigerant is used in the refrigeration cycle device (100) compatible with the R410A refrigerant is performed, a correction is performed to increase the first lower limit value to the second lower limit value, and the rotational frequency of the compressor (1) is controlled.
