PROBLEM TO BE SOLVED: To provide a refrigerant circulation path for beneficial use of an intermediate stage of the refrigerant circulation path by making a refrigerant of two-phase nature coming from a cylinder pass a third heat exchanger, capable of cooling a component of a vehicle down to a temperature level appropriate for cooling a battery and some power electronics of a vehicle.SOLUTION: A refrigerant circulation path includes a first heat exchanger 1 which forms a condenser, a second heat exchanger 2 for forming an evaporator, a first compressor C1, a second compressor C2, a first expansion valve D1, a second expansion valve D2, a cylinder B capable of separating liquid phase from vapor phase of refrigerant, and a third heat exchanger 3 which forms an evaporator. |
