A two stage intermittent solar refrigeration system is described briefly. In such a system, when flat-plate collectors are used for generation, it is very likely that the two generation temperatures are around the same value. The successful operation of the cycle under such conditions depends upon the proper selection of the initial solution concentrations in the high and low pressure generators and the volume ratio of the generators. These parameters have been evaluated with the help of the thermodynamic analysis of the refrigeration cycle operating with ammonia as the refrigerant and water as the absorbent. © 1986.
