The intermittent absorption refrigeration system with an ejector includes a generator/absorber unit, a solar collector unit, a dephlegmator, a condenser unit, a first evaporator, and valves to control the flow of aqua-ammonia coolant through the system, as in a conventional intermittent absorption refrigeration system. However, the present system also includes an ejector disposed between the dephlegmator and the condenser, and also a second evaporator disposed in a feedback loop between the first evaporator and the ejector, together with appropriate valves to control coolant flow through the feedback loop. The utilization of the ejector and the feedback loop in the intermittent system allows the intermittent system to produce a cooling effect during the daytime, as well as during the nighttime, which increases the coefficient of performance of the intermittent system.
