摘要：

In this paper, a 1.x-effect (hybrid ejector-absorption refrigeration working between single-effect and double effect) cycle is evaluated experimentally. Through the use of the ejector, the external heat sources' grade is reduced. Part of the refrigerant vapor at the outlet of the low-pressure generator is directly entrained by the refrigerant vapor from the outlet of the high-pressure generator to the condenser. The system with 10 kW cooling load is experimentally studied. The COP of the system is 30.0% higher than a single-effect absorption refrigeration system, and generation temperature is at least 20 degrees C lower than a double-effect absorption refrigeration system.
