Abstract (en)
A refrigeration system includes a refrigerant circuit including a gas-liquid separator ( 18 ) and operating in a two-stage compression and two-stage expansion refrigeration cycle. In the refrigerant circuit, intermediate-pressure gas-liquid two-phase refrigerant having flowed through an intermediate expansion valve after flowing through an outdoor heat exchanger is introduced through an inflow pipe ( 20 ) of the gas-liquid separator ( 18 ) into the vessel body ( 16 ) thereof and separated therein into liquid refrigerant and gas refrigerant. The liquid refrigerant flows out through a liquid outflow pipe ( 30 ), then flows through a main expansion valve and then through a refrigeration heat exchanger and is then sucked into a low-pressure stage compressor. The gas refrigerant flows out through a gas outflow pipe ( 40 ), is then fed to the suction side of a high-pressure stage compressor and is then sucked into the high-pressure stage compressor together with refrigerant discharged from the low-pressure stage compressor. The inflow pipe ( 20 ) is provided with a mesh member ( 50 ) for fragmentizing gas bubbles ( 80 ) of gas refrigerant in the gas-liquid two-phase refrigerant.
