Abstract
A refrigeration circuit includes: a gas-liquid separator into which a gas-liquid two-phase refrigerant flowed out from a condenser flows, the gas-liquid separator being configured to separate the gas-liquid two-phase refrigerant into a vapor phase refrigerant and a liquid phase refrigerant; and a plate heat exchanger including a first heat exchanging part and a second heat exchanging part, the first heat exchanging part being a part where the vapor phase refrigerant flowed out from the gas-liquid separator and the liquid phase refrigerant flowed out from the gas-liquid separator exchange heat, the second heat exchanging part being a part where the vapor phase refrigerant flowed out from the first heat exchanging part and a returning refrigerant flowed out from an evaporator exchange heat.
