Abstrakt: In the present work the operating process of a solar adsorption refrigerator based composite sorbent "silica gel/Na2SO4" is investigated. The graph of the temperature in the cold room in the winter and summer periods is analyzed. Its values are revealed to be lower than -10, it being hold constant for 10 hours. The cooling capacity and power dependence vs. cycle minimum temperature is stated. The highest efficiency of the cycle is observed with minimum temperatures in the cycle of 30-35°C, i.e. in the summer. It is found that with increasing of minimum temperature in the cycle determined by the ambient temperature is found to be accompanied coefficient of performance rising. Coefficient of performance increasing is shown to be resulted from rising of the salt content in the composite and, consequently, growth of the sorption capacity of the composite and the heat of sorption. The calculation of cooling rate and average daily cooling capacity to the experimental data and comparing of the results with those obtained by theoretical calculation is carried out. Close fit of theoretical and practical data is confirmed by corresponding of their divergence to acceptable accuracy for engineering calculations. [ABSTRACT FROM AUTHOR]
