Domestic refrigerators: Field studies and energy efficiency improvement

The paper reports the studies on evaluation of energy indices of domestic refrigerators of 165 L capacity in India. The specific energy consumption varies between 3.23 and 4.19 kWh/y/L for single door manual defrost units and between 3.84 and 4.78 kWh/y/L for double door auto defrost units. The major technical areas in a modernization programme are the use of alternatives to HCFC 22, the introduction of more efficient controls and better insulation.
