In order to study the coefficient of performance of the refrigerator it's required to apply some tools in order to measure the pressures and temperatures at all points in the pipes of the refrigerator that the study carried on for several days and different temperatures evaluated from 20C0 to 37C0. Data was obtained and calculated to measure the mean value of the coefficient of performance from the calculation the performance value increase from 20C0 until 28C0 and in that case, the coefficient of 28C0 was the peak of value.
