Abstract
A refrigeration apparatus has a refrigerant. The refrigerant is a non-azeotropic refrigerant mixture containing 50% by weight or more and 80% by weight or less of a high-boiling point refrigerant, 10% by weight or more and less than 50% by weight of a medium-boiling point refrigerant having a boiling point lower than that of the high-boiling point refrigerant, and 20% by weight or less of a low-boiling point refrigerant having a boiling point lower than that of the medium-boiling point refrigerant. The content of the high-boiling point refrigerant is larger than that of the medium-boiling point refrigerant, and the content of the medium-boiling point refrigerant is larger than that of the low-boiling point refrigerant. Piping through which the refrigerant derived from the compressor and flowing into the condenser passes includes a countercurrent flow configurator in which the refrigerant flowing through the piping is countercurrent to the cooling air.
