To provide a highly efficient and reliable refrigerating/air-conditioning device controlling a heat exchange amount in a second evaporator installed on a compressor suction side for properly controlling compressor intake in a refrigerating/air-conditioning device using an ejector.
The refrigerating/air-conditioning device is provided with the compressor 3, a condenser or a heat radiator 4, the ejector 5, and a refrigerating cycle formed by annularly connecting the evaporator. The evaporator is provided with a first evaporator 8 and the second evaporator 9. A liquid distributor 6 distributing a refrigerant from the ejector 5 to the first evaporator 8 and the second evaporator 9 is installed between the ejector 5 and the first and second evaporators 8 and 9. The outlet of the first evaporator 8 is connected to an intake part in the ejector 5, while the outlet of the second evaporator 9 is connected to the compressor 3. The refrigerant from the first evaporator 8 is sucked by the ejector 5 to be increased in pressure, and a gas-liquid two-phase refrigerant or liquid refrigerant is supplied to the second evaporator 9 by the distributor 6.
