Introduction
A refrigerator is an electrical device used in temperature maintenance below ambient temperatures. To achieve this function, the refrigerator should be able to create a heat sink at cold room temperatures a temperature that should be lower than the ambient temperature while at the same time also rejecting heats having higher temperatures than the ambient temperatures. To achieve this refrigerant is forced to undergo evaporation at temperatures lower than the ambient temperature(Griffiths, 1937). When the refrigerant is compressed at high pressure and condensing temperatures above the ambient temperature results in the loss of heat and condensation back to ...
