Abstract
An ejector refrigeration cycle includes a compressor, a radiator, a branch portion, an ejector, a suction side decompressor, a windward evaporator, and a leeward evaporator. The ejector includes a nozzle portion and a pressure increasing portion. The windward evaporator and the leeward evaporator include at least one outflow side evaporation portion. The leeward evaporator includes a suction side evaporation portion. An outflow side evaporation temperature is a refrigerant evaporation temperature in the at least one outflow side evaporation portion of the leeward evaporator. A suction side evaporation temperature is a refrigerant evaporation temperature in the suction side evaporation portion of the leeward evaporator. At least one of the nozzle portion or the suction side decompressor is configured to adjust a refrigerant passage area such that a temperature difference between the outflow side evaporation temperature and the suction side evaporation temperature is at or below a predetermined reference temperature difference.
