Abstract
In this investigation, a prototype model of the solar adsorption refrigeration system was constructed and its performance was evaluated with different mass ratios of adsorbents in the laboratory for possible field application. The main components of the solar-driven cooling system were vacuum tube collector, adsorption bed, condenser, evaporator, chilling chamber, and temperature data logger. The experimental study was conducted to analyze the performance of solar cooling unit using different mass ratios of activated carbon–methanol from 0.250 to 2.50. A minimum cooling temperature of 12.2 °C was obtained with the manually prepared activated carbon–methanol with mass ratio of 1.00. The cooling coefficient of performance and specific cooling potential was also evaluated from performance calculations.
