The influences of operating parameters (condenser inlet water temperature

high-temperature evaporator inlet water temperature and low-temperature evaporator inlet water temperature) on the performance of bi-evaporator compression/ejection refrigeration cycle (BCERC) and two-phase ejector are experimentally investigated. Results show that the ejector entrainment ratio decreases with the rising of condenser inlet water temperature and high-temperature evaporator inlet water temperature

but rises with the increasing of low-temperature evaporator inlet water temperature. The pressure lift ratio of ejector increases with the rising of condenser inlet water temperature and high-temperature evaporator inlet water temperature

but decreases with the rising of low-temperature evaporator inlet water temperature. The condenser inlet water temperature and the high-temperature evaporator inlet water temperature have significant influences on the performance of the BCERC system. However

the low-temperature evaporator inlet water temperature has little effects on the performance of the BCERC system. As the condenser inlet water temperature decreases 5℃

the COP increases 0.44. As the high-temperature evaporator inlet water temperature increases 2℃

the increase of system COP is 0.16. The results can be references for the design and operation of the BCERC system.
