Many agricultural producers are stored at very low temperature to avoid unwanted damages to produces and thus to increase their shelf life.
Reducing temperature of a store using electricity, according to its cooling load, is expensive and complex.
However, incorporation of solar photovoltaic technology would improve this system for better capacities.
Solar thermal refrigerators are now becoming popular in agricultural sector, which are divided into sorption refrigerators, and solar thermal mechanical refrigerators with specific configurations.
Many researches are being under taken by many researchers in this sector.
