ABSTRACT:
An absorption refrigerating unit for refrigerating plural refrigerating compartments. A single pathway of coolant includes a coolant vapor generator, a vapor condenser at the top of the unit, a first partial evaporator for partially evaporating the liquid coolant by absorption of heat, a second partial evaporator, following the first partial evaporator in the coolant pathway, also for partially evaporating the liquid coolant by further absorption of heat. A first of a plurality of secondary cooling systems includes a chamber located at the first partial evaporator at which vapor form second coolant is cooled to liquid form and that liquid second coolant is delivered in a coolant pathway to a first of the refrigerating compartments to be cooled, there to absorb heat and be revaporized to return to the chamber around the first partial evaporator. A separate second one of the secondary cooling systems includes its own chamber and communication to the second refrigerating compartment for cooling the same. A gas heat exchanger is in the coolant pathway between the partial evaporators. The refrigerating compartments are disposed beneath the respective partial evaporators and beneath the condenser.
