<P>PROBLEM TO BE SOLVED: To suppress occurrence of high temperature due to mutual direct contact of metal so that decomposition and polymerization of material having a double bond between carbon atoms are suppressed. <P>SOLUTION: A compressor 200 includes: a compression element 101 having a sliding member 3 and compressing coolant; and an electric element 102 driving the compression element 101, and uses, as the coolant, either a halogenated hydrocarbon having a double bond between carbon atoms in the composition; a hydrocarbon having a double bond between carbon atoms in the composition; or a mixture including at least either a halogenated hydrocarbon having a double bond between carbon atoms in the composition or a hydrocarbon having a double bond between carbon atoms in the composition. In the compressor 200, at least either a surface of a sliding contact part 3a of the sliding member 3 of the compression element 101, or a surface of a sliding contact part of a counter part member 1 with which the sliding member 3 slidingly contacts is made of a nonmetal material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
