Abstract
Disclosed is a non-azeotropic refrigerant mixture containing tetrafluoropropane as a high-boiling refrigerant and a refrigeration cycle apparatus in which a non-azeotropic refrigerant mixture containing tetrafluoropropane as a high-boiling refrigerant circulates through a refrigeration cycle so as to avoid occurrence of negative pressure in a low-pressure circuit. The non-azeotropic refrigerant mixture is characterized in that a mixing ratio of a high-boiling refrigerant and a low-boiling refrigerant is determined so that a saturated vapor line where pressure is 0.00 MPa is not higher than −45° C. in a low-pressure circuit formed between the decompressor to the compressor.
