The performance analysis of a solid adsorption solar refrigerator during collector cool-down and refrigerant evaporation/re-adsorption phases

摘要

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 per cent when the initial adsorbate concentration was dropped from 0.29 to 0.21 kg/kg, while the mass of ice produced increased from 0 kg of ice/kg of adsorbent to 0.4 kg of ice/kg of adsorbent for the same range of variation of initial adsorbate concentration.
