Maharashtra State Board: Class 11
Definition: Refrigerator
A device that extracts heat from a cold region and delivers it to the surroundings, further cooling the cold region (where QC > 0, QH < 0, W < 0) is called a refrigerator.
OR
A system that requires external work to transfer heat from a lower temperature to a higher temperature, with its performance measured by the Coefficient of Performance (COP), is called refrigeration.
Maharashtra State Board: Class 11
Formula: Refrigeration
COP = \[\frac {\text {Heat removed from cold reservoir}}{\text {Work input}}\]
