Solar Refrigeration for Post-Harvest Crops Reservation: The State Of Art of the Systems

摘要

Renewable Energy Resources is being used to provide an electrical power source through using appropriaterntechnologies like Photovoltaic, Wind Turbine or Hybrid Technology associated with storage system tornprovide the needed power during the period when these renewable energy resources are not available. Therernare many agriculture crops that are being cultivated in Egypt reclaimed deserts areas. Therefore, to deliverrnsuch crops at high product quality, after harvest to the consumers, the transport storage environment need tornbe at appropriate temperature and humidity levels to maintain highest product quality to the end user. Solarrnenergy is being utilized to be used for cooling and refrigeration. This paper presents the state of art of solarrndriven refrigeration systems that used for agriculture crops reservation. It concluded that solar driven vaporrncompression refrigeration system is the most appropriate system for this application. This due to it has higherrnCOP than the solar thermal refrigeration systems. Moreover, its size (footprint) is smaller than other solarrndriven refrigeration systems as well as it could be easily transportable. The main hindrance of this its higherrninitial cost compared to other conventional driven refrigeration systems.
