Abstract
A refrigerant cycle system includes a condenser having a condensation portion for condensing refrigerant discharged from a compressor, and a receiver for separating refrigerant from the condensation portion into gas refrigerant and liquid refrigerant, and for storing the liquid refrigerant. In this system, refrigerant from the condensation portion flows into the receiver through a first communication hole, and liquid refrigerant in the receiver is discharged through a second communication hole in which a pressure loss is generated. Further, gas refrigerant at an upper side in the receiver is discharged to a downstream side of the second communication hole through a gas bypass pipe.
Claims20
A refrigerant cycle system comprising:
- a compressor for compressing refrigerant;
- a condenser having a condensation portion for cooling and condensing refrigerant discharged from the compressor;
- and
- a receiver for separating refrigerant from the condensation portion of the condenser into gas refrigerant and liquid refrigerant, and for storing the liquid refrigerant therein, wherein:
- the condenser and the receiver are disposed to have a first refrigerant passage through which refrigerant after passing through the condensation portion flows into the receiver, a second refrigerant passage through which liquid refrigerant stored at a lower side in the receiver flows outside the receiver, and a third refrigerant passage having two end portions with a pressure difference, through which gas refrigerant staying at an upper side in the receiver is discharged to a downstream side of the receiver.
