Abstract

The problem of preserving vaccines as well as perishable foodstuffs is absolutely conditioning the life of populations living in intertropical areas, that is to say, population deprived of all energy forms other than the one coming from the solar radiation. Vaccines keep their properties if their temperature is maintained between −3°C and 8°C, without taking the ambient temperature into accout. Also some foodstuffs need a temperature of between 0 and 10°C for preservation in a good condition. However, in some areas in the Sudan, day temperature can reach and even exceed 40°C. So a cooling of these materials is imperative. Nevertheless, without having a conventional energy source at one's disposal, the existence of mechanical refrigerators connected to photovoltaic panels could present a possible solution to this difficulty. This paper presents a field test of the performance of photovoltaic (PV) refrigerator in the Sudan tropical climate.
