And air conditioner refrigerant circuit

The present invention includes: a gas-liquid two-phase refrigerant (51) into refrigerant vapor (52) and a refrigerant liquid (53) a plurality of gas-liquid separator (1); and an upstream gas-liquid separator (1) and the connection-side opening and closing the switching flow path that gas-liquid two-phase refrigerant (51) a switching valve (11); separated in the gas-liquid separator (1) in a refrigerant liquid (53) or gas-liquid two phase refrigerant (51) flows into the evaporator heat exchanger (3); with respect to the evaporative heat exchanger (3) perpendicularly or obliquely disposed upstream of the evaporator heat exchanger (3) of the headers (2); provided in downstream of the compressor side of the evaporator heat exchanger (3) (7); and a connection to the respective gas-liquid separator (1) for refrigerant vapor and (52) a plurality of bypass path (6) through a plurality of the refrigerant vapor (52) after the bypass path (6) through the evaporator and the vapor refrigerant heat exchanger (52) after the (3) in the evaporator heat exchanger (3) and the compressor (7) between the first meeting point α converge.
