Abstract
A supercritical refrigeration cycle system () having a simplified flow path configuration comprises a compressor () for sucking in and compressing a refrigerant, a radiator () for radiating the heat of the high-pressure refrigerant discharged from the compressor (), a high-pressure control valve () and a superheat control valve () into which the high-pressure refrigerant flowing out of the radiator () flows after being distributed, a first evaporator () for evaporating the influent refrigerant decompressed by the high-pressure control valve (), and a second evaporator () for evaporating the influent refrigerant decompressed by the superheat control valve (). The outlet of the second evaporator () and the inlet of the first evaporator () are connected to each other by the refrigerant path () in such a manner that the refrigerant flowing out of the second evaporator () flows into the first evaporator (). An increase in the blowout air temperature can be reduced by controlling the refrigerant flowing in each of the plurality of the evaporators.
