AbstractThis research was to modify one of the solar powered refrigerators (Model I) constructed at AIT by Exell and Kornsakoo (1978) as another step towards the development of a self-acting system without the need for hand valves or automatic valves. The main part of the work was the study and analysis of two non-return liquid seals, one on each of a pair of solar collector panels. Tests showed that unequal performance of the two collectors prevented the seals from performing in the correct way simultaneously, and future designs should use one seal only for a system of panels. An attempt has been made to explain the behaviour of the seals but the experimental observations are still not fully understood. The work done included the substitution of copper sheet by galvanized iron sheet in the collector panels for structural reasons, and theoretical comparison of the performances of refrigeration by means (a) an expansion valve and evaporator coil and (b) a flooded evaporator coil without any expansion valve.
