Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2019015495
Kind Code:
A
Abstract:
To provide a refrigeration cycle device having an ejector capable of flowing a sucked refrigerant down to a compressor by increasing pressure of the refrigerant.SOLUTION: An ejector 100 has: a driving refrigerant inflow port 111 which flows in a first refrigerant evaporated by a first evaporator; a sucked refrigerant inflow port 121 which causes a second refrigerant evaporated by a second evaporator to flow in; a shrunk diameter part 131 joining the first refrigerant flown in from the driving refrigerant inflow port 111 and the second refrigerant flown in from the suction refrigerant inflow port 121; a nozzle throat part 113 narrowing a flow path of the first refrigerant flown in from the driving refrigerant inflow port 111; and a nozzle diffuser part 114 having a columnar or conical flow path causing the first refrigerant passing the nozzle throat part 113 in an upstream of the shrunk diameter part 131 to pass. On a plane surface passing a central line C, an angle α inside the nozzle diffuser part 114 is between 0° and 12°.SELECTED DRAWING: Figure 3
