COMPRESSOR AND REFRIGERANT SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce a leakage current from a compressor and a system using the same by reducing permittivity of film insulation of a slot insulating part of a rotating machine composing a compressor, and nonpolarizing the operation fluid used therefore, in order to prevent deterioration of efficiency correspondingly to increase of frequency in controlling a refrigerant system. SOLUTION: A polyethylene terephthalate film having bores is adopted to a slot insulating part of a rotating machine. Propane and mineral oil are user as refrigerant and lubricating oil respectively of operation fluid of compressor. A refrigerant system is composed by connecting a condenser, an expansion valve, an evaporator to the rotating machine and the compressor.
