MODELING AND DEVELOPMENT OF GENERATOR-ADSORBER OF ECOLOGICALLY SAFE SOLAR-POWERED REFRIGERATING UNIT

摘要

Problems of modeling a generator-adsorber as the basic apparatus of solar-powered refrigerating unit are examined from the standpoint of analysis of effective optical and heat-energy characteristics in "hot box" type of solar heat collector. Based on this model, a procedure for calculating the useful heat load on the generator-adsorber reactor is proposed and the additivity of the model is checked by calculation and experimental data from the tests of the developed generator-adsorber of the solar-powered refrigerating unit. Heat flows and temperature gradients inside two designs of reactors, namely, a simple design with an offset cold conducting tube and a design with internal finning, are modeled. An experimental generator-adsorber apparatus with optimum technical specifications is designed, a procedure for determining useful heat loads on the apparatus is developed, and ways of predicting efficient reactor designs are proposed.
