摘要： It is determined whether thermo-off postponement control is allowed or not on the basis of a current compressor operating frequency when a thermo-off condition is satisfied. If it is determined that thermo-off postponement control is allowed, the thermo-off postponement control in which a lowest operating frequency in an operating frequency range of a compressor is temporarily reduced within a range greater than or equal to a minimum operating frequency of the compressor in use so as to continue an operation. If it is determined that thermo-off postponement control is not allowed, thermo-off of stopping the compressor is performed.

摘要： A refrigeration cycle apparatus includes a compressor and sets a heating-mode lower limit refrigerant volume flow rate through the compressor. The heating-mode lower limit refrigerant volume flow rate is a lower limit of a volume flow rate in a heating operation. The apparatus controls a rotation speed of the compressor such that the volume flow rate in the heating operation is greater than or equal to the heating-mode lower limit refrigerant volume flow rate. The heating-mode lower limit refrigerant volume flow rate includes a first lower limit for use of an R410A refrigerant and a second lower limit for use of an R32 refrigerant. When using the R32 refrigerant in the refrigeration cycle apparatus designed for the R410A refrigerant, the apparatus performs correction such that the lower limit is increased from the first lower limit to the second lower limit to control the rotation speed of the compressor.
