Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2013253734
Kind Code:
A
Abstract:
To provide a refrigeration cycle device in which discharge gas temperature of a refrigerant compressor is decreased.
A refrigeration cycle device A1 is characterized to include a machine oil cooling mechanism 15 in which a compressor 1, a condenser 18, a pressure reducing device 19 and an evaporator 20 are sequentially connected by piping to constitute a cycle flow path of the refrigerant, and machine oil stored in the compressor 1 is cooled by a refrigerant delivered from the condenser 18. Particularly, in the refrigeration cycle device A1 using HFC32 as a refrigerant, deterioration of a resin component in an electric motor part of the compressor 1 can be suppressed by decreasing discharge gas temperature of the compressor 1.
