POLICE OFFICER (coefficient of effectiveness β) for a truly excellent refrigeration cycle is described since the proportion of the heat got rid of per cycle (W) to remove this heat (QL) from the compound to the job achieved per cycle.

β= WQL

If QH is the heat offered to provide at temperature level TH, after that by the main regulation of thermodynamics.

QL − QH= − W

or QH − QL= W

For That Reason β= QH − QL QL

or β=( QH/ QH) −( QL/ QH)( QL/ QH)= 1 −( QL/ QH) QL/ QH
