Design and fabrication of energy efficient of frost and non frost chamber of a refrigeration with the same compressor and condenser.

Abstract

Refrigerators used in daily life are one of the indispensable tools. Uninterrupted power should be supplied to the refrigerators in order to maintain cooling service. Domestic refrigerator may be operating continuously to maintain proper food storage condition. The continuous operation of this equipment accounts more electrical consumption. A significant amount of waste heat is rejected by the condensers of refrigerator Although the given project has two chambers, with the help of a plressure valve, the gas flow should be stopped in one of the chambers and the gas flow should be opened in the other chamber by opening the pressure valve. To Start the frost phase chamber, the non frost timer switch should be dopt off. In this way, the same compressor and two chambers can be operated by the same condenser.
