An object of the present invention is to improve the reliability while attaining energy saving, miniaturization and high efficiency of a refrigeration apparatus using a hydrocarbon refrigerant.n n n A refrigeration apparatus using a hermetic compressor, in which a compression element and a transmission element are accommodated in a sealed container, and a crankshaft driven by the transmission element and a piston are connected by a cone rod, wherein the isobutane R600a is compressed by the compression element. By using as a freezer oil, the fatty acid ester oil which has an ester bond in a molecule | numerator is used as a refrigerator oil, and it improves the lubricity of a sliding part, and achieves high efficiency and reliability improvement. |
