This review paper is a study on various methods of performance improvement in domestic refrigeration systems, based
on the vapor compression refrigeration VCRS cycle. Here air-cooled, water-cooled, fog cooled, evaporatively cooled condensers
and nano-fluid lubricant /coolant methods their working and efficiency are reviewed, compared, analyzed and presented. The
paper inspects the work done by different researchers for the maximization of heat loss from condenser & compressor and
bringing about necessary modifications to reduce the overall power consumption of domestic refrigerators by improving
Coefficient of Performance (COP).
