| Summary: | In this research a study of the theory of six different adsorption pairs to check and choose the best adsorption pair in terms of adsorption capacity and the effect of high and low temperature on it. It has been shown that the best adsorption pair at the temperature 25oC is the activated carbon fiber with methanol (ACF + CH3OH). Where the adsorption capacity is = 0.45 ACF x , followed by granules of 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 and a couple for solar adsorption chiller system. The application of Excel has been used to solve governing equations and mathematical model of thermal balance simulation the largest amount of ice produced, the highest coefficient of performance for all pairs adsorption mentioned at the best operational temperature, it was found that the activated carbon fiber with methanol, the largest amount of ice produced 2.55kg and the highest coefficient of performance of 0.38 in the adsorption ice maker at operating temperature of generator is (110oC). The Adsorption chiller for a couple, silica gel with water, the best in terms of impact with the cooling effect and coefficient of performance of the highest at temperature range of (64 -110oC). |
