Experimental investigation of a combined ejector-absorption refrigerator

This paper describes an experimental study of a novel heat-operated refrigeration cycle, 'combined ejector-absorption refrigeration cycle'. In this novel cycle, an ejector was placed between a generator and a condenser of a conventional single-effect absorption refrigerator. The high-pressure vapour refrigerant produced in the generator section was used as the motive fluid for the ejector which entrained low-pressure refrigerant vapour from the evaporator and discharged it to the condenser. This was shown to significantly increase the cooling capacity and COP of the novel refrigerator above that of a conventional absorption unit with little increase in system complexity.
