Abstract

Refrigerator and air conditioning consumes most of energy in industry or even at domestic or home applications. They also use refrigerant that harmful to the environment such as depletion of the ozone layer. This project is to fabricate a refrigerator that consume less energy and less harmful substances as refrigerant compare to the typical refrigerator. The size of the refrigerator is focused on mini sized fridge. The cooling method for this project is using the expansion of the liquefied petroleum gas (LPG) from the tank. The high pressure of LPG from the tank is expands by lowering the pressure using expansion device just like the vapor compression cycle in refrigerator and air conditioning. The project also has the same function as refrigerator and also have burner or stove for cooking as the final use of the LPG after the expansion. The result of the project is the project will have the same function as the domestic refrigerator that provides cooling to keep food in lower temperature. There are more ways and methods to save energy and using natural resources is one of the best method.
