Abstract
An amount of refrigerant fed to an evaporator 16 is adjusted by an open degree of an expansion valve 6 in accordance to a refrigerant pressure and a refrigerant temperature of an outlet side of the evaporator 16. The evaporator 16 has an evaporation part which includes a refrigerant passage 26 connecting parallel with an inflow passage 22 and an outflow passage 24 and further having a cooled passage 28 which forms a first throttle 30 at the downstream thereof and a cooling passage 32. The cooled passage 28 links the expansion valve 6 and the inflow passage 22. The cooling passage 32 is connected to the outflow passage 24 and leads refrigerant to an outlet. A heat exchange part 20 is provided to be able to of performing heat exchange between the cooled passage 28 and the cooling passage 32. A second throttle is set in a bypass passage 38 which links the upstream side of the cooled passage 28 and the downstream side of the first throttle 30.
