Parametric Effects on the Performance of a Solid Adsorption Solar Refrigerator During Collector Cool-Down and Refrigerant Evaporation/Readsorption Phases

The performance analysis of a solid adsorption solar refrigerator during the collector cool-down and refrigerant evaporation/re-adsorption phases is presented. The effects of the condenser pressure, evaporator pressure and initial adsorbate concentration on the collector cool-down and refrigerant evaporation/re-adsorption were tested. The adsorbate concentration re-adsorbed increased from 55% to 98% when the initial adsorbate concentration was dropped from 0.29kg/kg to 0.21kg/kg while the mass of ice produced rose from 0kg to 1.5kg for the same range of variation of initial adsorbate concentration.
