    The performence of a refrigeration system is expressed by term known as the "co-efficient odf performance", which is defined as the ratio of heat absorbed by the refrigerant while passing through the evaporator to the work input required to compress the refrigerant in the compresser ; in short it is the ratio between heat extracted to work done (in heat units).
