Abstract

The design of a commercially available vapour-absorption-type electrical refrigerator was changed to make it suitable for running on solar energy. The refrigerator was attached to an east-west oriented parabolic cylindrical collector to supply heat to the generator of the refrigerator. The test results revealed that the minimum temperature in the evaporator was 3°C. The coefficient of performance of the refrigerator was 1·73. The designed collector and the heating pipe were suitable for the operation of the refrigerator by solar energy. From the analysis of the operation of the refrigerator by both electrical as well as solar energy it was found that the heat supplied to the generator and the refrigerating effect was less in the latter case. The major factors behind this are the variation of heat supply and the low intensity of solar radiation.
