Abstract
A decompressing device for decompressing refrigerant that is discharged from a compressor is provided at an inlet of a hot-gas bypass passage. The refrigerant flows in the hot-gas bypass passage after being decompressed by the decompressing device to bypass a condenser at a heating mode. In this case, because the refrigerant flows in the hot-gas bypass passage with a temperature that is lowered by the decompression, heat loss at a pipe portion of the hot-gas bypass passage is effectively decreased.
Claims24
A refrigerating cycle system comprising:
- a compressor for compressing refrigerant and discharging the refrigerant in a gaseous state;
- a condenser for condensing the refrigerant that is discharged from the compressor;
- a first decompressing part for decompressing the refrigerant that is condensed by the condenser;
- a second decompressing part for decompressing the refrigerant that is discharged from the compressor in the gaseous state;
- a valve member for switching refrigerant flows from the compressor into the condenser and from the compressor into the second decompressing part;
- an evaporator for evaporating the refrigerant that is decompressed by one of the first and second decompressing parts;
- and
- a hot-gas bypass passage directly connecting the compressor and the evaporator while bypassing the condenser, and including the second decompressing member at an inlet thereof on a compressor side.
