Simulation Study and Comparison Green Freeze Technology Utilizing with Theory of Different Adsorption Working Pairs of Solar Adsorption Refrigeration

Abstract

In this research a study of the theory of six different adsorption pairs to checkand choose the best adsorption pair in terms of adsorption capacity and the effect ofhigh and low temperature on it. It has been shown that the best adsorption pair atthe temperature 25oC is the activated carbon fiber with methanol (ACF +CH3OH). Where the adsorption capacity is = 0.45 ACF x , followed by granulesof activated carbon with methanol (AC + CH3OH) and adsorption capacity is= 0.3 AC x by more than half compared to a pair of activated carbon fibers. Then,four adsorption pairs have been selected for solar adsorption ice maker system anda couple for solar adsorption chiller system. The application of Excel has been usedto solve governing equations and mathematical model of thermal balancesimulation the largest amount of ice produced, the highest coefficient ofperformance for all pairs adsorption mentioned at the best operational temperature,it was found that the activated carbon fiber with methanol, the largest amount ofice produced 2.55kg and the highest coefficient of performance of 0.38 in theadsorption ice maker at operating temperature of generator is (110oC). TheAdsorption chiller for a couple, silica gel with water, the best in terms of impactwith the cooling effect and coefficient of performance of the highest at temperaturerange of (64 -110oC).
