Embodiment Construction
[0015] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0016] Such as figure 1 As shown, the cascade refrigeration cycle system that utilizes the exhaust sensible heat of the refrigeration compressor and the coupling of the ejector includes a high-temperature stage compressor, a low-temperature stage compressor, a three-channel generator, a condenser, and a condensation evaporator , throttle valve, gas-liquid separator, evaporator, ejector, liquid booster pump, liquid level controller, solenoid valve, pressure sensor, temperature sensor, etc.
[0017] Its refrigeration cycle method is:
[0018] The saturated liquid refrigerant condensed by the condenser is divided into two paths, one path passes through the throttle valve to reduce temperature and pressure, and the other path passes through the liquid booster pump to pressurize and enter the three-channel generator. The level controls the start and stop of the ...
