The paper presents the developed circuit solutions for alternative refrigeration systems based on the of heat-absorption cycle and solar energy utilization for regeneration (recovery) of the absorbent solution. Cascade principle of heat-mass exchange apparatuses construction was applied, of drying and cooling loops with varying of temperature level and increasing of absorbent concentration on the cascade steps. Film type heat and mass transfer equipment, which is the part of the drying and cooling loops is unified and executed on the basis of monoblock polymeric materials compositions. The preliminary analysis of solar refrigeration systems potentialities was carried out.
