REFRIGERATION CYCLE DEVICE, AIR CONDITIONING DEVICE, AND METHOD FOR CALCULATING CIRCULATION COMPOSITION IN REFRIGERATION CYCLE DEVICE

摘要

A refrigeration cycle device equipped with a control device (50) having: an excess refrigerant determination means, which determines whether excess refrigerant is present in an accumulator (14); and a refrigerant composition calculation means that uses a different method to calculate a circulation composition when the excess refrigerant determination means determines that excess refrigerant is not present than when the excess refrigerant determination means determines that excess refrigerant is present, said circulation composition being the composition of at least one refrigerant component of multiple refrigerant components when a non-azeotropic refrigerant mixture is circulating in a refrigerant circulation circuit (1).
