An experimental hybrid system for the drying of grains, which does contain chlorine and does not destroy the ozone layer is designed, constructed, operated, and energetically evaluated. In this experiment rice is dried. It is made up of three systems: 1.-heat pump with mechanical compression, 2.-solar air heater, 3.- dryer for agricultural products. The capacity of the dryer is approximately 10 kg per day, assuming an average day of solar radiation. It has a total cost of approximately $60,000 dollars. The heat pump uses refrigerant 22, and refrigerant SUVA 9000 will be utilized in the second generation. This refrigerant will be commercialized in the year 2000 in the American Union. It belongs to the group of refrigerants referred to as ecological which are substitutes for choloroflourocarbon refrigerants. |
