Title: EJECTOR REFRIGERATION CYCLE DEVICE
Abstract:
An ejector refrigeration cycle device comprises: a radiator (12) that radiates heat from refrigerant delivered from a compressor (11); an ejector module (13) that reduces the pressure of the refrigerant cooled in the radiator (12); and an evaporator (14) that evaporates liquid phase refrigerant that is separated in a gas-liquid separation space (30f) of the ejector module (13). Furthermore, a grill shutter (16) serving as an inflow pressure increasing unit is disposed between the radiator (12) and a cooling fan (12d) that blows outside air toward the radiator (12). In addition, when the outside air temperature (Tam) is at a predetermined reference outside air temperature (KTam) or lower, the grill shutter (16) is operated so as to reduce the amount of outside air blowing toward the radiator (12) and the pressure of the inflow refrigerant flowing to a nozzle passage (13a) of the ejector module (13) is increased.
