Design of a refrigerated complex for short-term storage of tropical fruits with a solar energy plant

The object of research is a refrigerated complex for short-term storage tropical fruits in conditions significant seasonal and daily fluctuations ambient temperature, that typical regions with climate. One the problems complexes are autonomous small firms year-round processing fruits, located far from central electric networks. In presence solar radiation, receive energy power plants. Such called «trigeneration system». course study, data on modes were used low temperature heat treatment preservation various ripening times climatic Tunisia. It has been established citrus stored chambers high olives frozen short time before processing. total amount entering determined by changes temperature. thermal load chamber time. was found cargo capacity different temperatures differs six times. olive only four less. This due to peculiarities building structure complex, technological processes cooling freezing. Based calculation, provided two-stage booster refrigeration machine CO2 refrigerant transcritical cycle. To ensure operation photoelectric converter designed. ensures environmental safety possibility obtaining savings regulating compressors frequency converters, depending designed can be offered private investor practical implementation.
