Abstract

A freezer using an enclosed compressor having an enclosed container with a compression element and an electrically driven element stored therein, a crank shaft 7 and a piston 4 driven by the electrically driven element being connected by a con rod 2, and a connection portion between the con rod 2 and the piston 4 being slidable, wherein isobutane (R600a) is used as a refrigerant compressed by the compression element and fatty ester oil having an ester linkage in the molecule is used as freezer oil. Thus energy conservation, miniaturization, and high efficiency of a freezer using a hydrocarbon series refrigerant are realized, and the reliability thereof is improved.
