초록

A refrigerant circulating system that uses a highly polar refrigerant, as typified by a hydrofluorocarbon-based one, and a refrigerating oil that has slight solubility with a liquid refrigerant on the condensation side. Also, a refrigerant circulating cycle that uses a highly polar refrigerant, as typified by a hydrofluorocarbon-based one, and a refrigerating oil that has a slight solubility with a liquid refrigerant and which has a greater specific gravity than the liquid refrigerant. Thereby, it provides a high electrical insulation and moisture resist...

청구항

A refrigerant circulating system comprising: a compressor that uses a hydrofluorocarbon based single or mixed refrigerant and which draws in a gaseous refrigerant containing a liquid refrigerant while discharging it as a high-pressure gaseous refrigerant; a condenser positioned downstream of said compressor for condensing the high-pressure gaseous refrigerant discharged from said compressor; a throttle mechanism positioned downstream of said condenser for reducing a pressure of a liquid refrigerant leaving said condenser; and an evaporator positioned dow...
