Refrigerant cycle system
First Claim
1. A refrigerant cycle system comprising:
- a compressor which compresses and discharges refrigerant;
a condenser for cooling and condensing refrigerant discharged from the compressor;
a decompression device decompressing refrigerant from an outlet of the condenser; and
an evaporator for evaporating refrigerant from the decompression device, the evaporator being disposed so that refrigerant from the evaporator is sucked into the compressor, wherein;
the condenser includes a first heat exchange unit, a second heat exchange unit at a downstream side of the first heat exchange unit in a refrigerant flow direction, and a gas liquid separator arranged between the first heat exchange unit and the second heat exchange unit in the refrigerant flow direction in such a manner that refrigerant discharged from the compressor is cooled in the first heat exchange unit and at least gas refrigerant separated in the gas-liquid separator flows into the second heat exchange unit; and
in the condenser, a refrigerant state flowing from the first heat exchange unit to the gas-liquid separator is changed in accordance with a super-heating degree of refrigerant discharged from the compressor to change a liquid refrigerant amount stored in the gas-liquid separator.

Abstract
A condenser of a refrigerant cycle system includes a first heat exchange unit into which refrigerant discharged from a compressor flows, a second heat exchange unit disposed at a downstream of the first heat exchange unit in a refrigerant flow direction, and a gas-liquid separator disposed between the first and second heat exchange units in the refrigerant flow direction. In the refrigerant cycle system, at least gas refrigerant separated in the gas-liquid separator flows into the second heat exchange unit so that an amount of liquid refrigerant stored in the gas-liquid separator is changed in accordance with a super-heating degree of refrigerant discharged from the compressor.
