Title:
COMPRESSOR, REFRIGERATION CYCLE DEVICE, AND HEAT PUMP HOT-WATER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/083674
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a compressor capable of reducing the amount of refrigerator oil that flows from a first discharge path; a refrigeration cycle device comprising said compressor; and a heat pump hot-water supply device. This compressor comprises: a sealed container; a first intake path that takes in refrigerant; a compression element provided inside the sealed container and which compresses refrigerant taken in from the first intake path; the first discharge path that discharges refrigerant compressed by the compression element to outside the sealed container; a second intake path that takes into the sealed container refrigerant that has been discharged from the first discharge path and has passed through an external heat exchanger; a second discharge path that discharges to outside the sealed container refrigerant that has been taken inside the sealed container from the second intake path; and an oil return means that guides refrigerator oil that is inside the first discharge path to inside the sealed container.
