Performance of a photovoltaic solar refrigerator in tropical climate conditions

By: El Tom, O.M.M | Omer, S.A | Taha, A.Z | Sayigh, A.A.M

Publisher: Technical Information Service ; Bangkok ; October 1990Description: 8 p; illSubject(s): ENERGY | ENERGY SOURCES | SOLAR RADIATION | SOLAR ENERGY | REFRIGERATION | TROPICAL ZONESummary: The problem of preserving vaccines as well as perishable food stuffs is absolutely conditioning the life of populations living in inter tropical 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 -30 and 8 degrees celsius, without taking the ambient temperature into account. Also some foodstuffs need a temperature of between 0 and 10 degrees celsius for preservation in a good condition. However, in some areas in the Sudan, day temperature can reach and even exceed 40 degrees celcius. 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 (PV) refrigerator in the Sudan tropical climate.
