Abstract:
The intermittent absorption refrigeration system includes a primary circuit having a generator/absorber, a dephlegmator, a condenser, an evaporator, and solar collectors to provide heat to the generator. The system also includes an ejector-based secondary circuit having a generator/absorber, an ejector, a condenser, a refrigerant storage unit, and solar collectors. Both circuits are aqua-ammonia systems, using ammonia as the refrigerant and water as the absorber liquid. The ejector permits evaporation during the daytime and storage of liquid ammonia refrigerant that is used for cooling in the heat exchanger of the primary circuit condenser and in the primary circuit absorber, thus permitting the primary circuit evaporator to operate at lower temperatures for low temperature freezing applications in the daytime, even at high ambient temperature.
