Abstract

The paper details the design and simulation of a solar powered apour compression refrigeration system. The effect of a phase change aterial, in this case ice, on a vapour compression refrigeration system owered by solar panels is discussed. The battery and solar panels were sized to allow the system to function as an autonomous unit for a minimum of 12 ours. It was concluded that the presence of a phase change material in the efrigeration system caused a considerable increase in both the on and off time of the compressor. The ratio by which the on time increased was greater han the ratio by which the off time was increased. There was a 219% ncrease in the on time, a 139% increase in the compressor off time and a 3.5% increase in compressor work accompanied by a 5.5% reduction in OP. Thus, under conditions where there is enough load in the system to ause the initial on and off times of the compressor to be comparable, the presence of a phase change material may result in a greater on period than n off period for the compressor
