Abstract:
A refrigeration cycle through which a refrigerant flows comprising:a compressor which compresses the refrigerant and discharges a gas refrigerant;a condenser which condenses the gas refrigerant discharged from the compressor;a decompressing unit which decompresses the refrigerant condensed by the condenser;an evaporator which evaporates the refrigerant decompressed by the decompressing unit; anda bypass passage which directly connects an outlet of the compressor to an inlet of the evaporator, the bypass passage through which the gas refrigerant discharged from the compressor is directly introduced into the evaporator in a heating mode, wherein:the decompressing unit is disposed in a passage between the condenser and the evaporator; andthe decompressing unit is disposed to always open the passage between the condenser and the evaporator by a predetermined opening degree when a refrigerant recovery mode in which the refrigerant staying in the condenser is forced to be discharged and introduced into the evaporator is set even in the heating mode.
