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.
An evaporator for cooling units to be installed in the downstream from a pressure reducing value in a refrigerating cycle for circulating refrigerant, said evaporator comprising:
A refrigerating cycle unit comprising:
