Abstract
This work investigates the results of an experimental study carried out to determine capacitor effects on the steady state performance of a household refrigerator under various thermal loads. The performance parameters investigated are the refrigeration capacity, the amount of heat rejected to ambient, the compression work, and the coefficient of performance. A capacitor whose size is 6 mu F was installed onto the refrigerator electric circuit. Continuous running tests in which compressor runs continuously without stopping were performed with and without the capacitor under varying thermal loads and test data were recorded after the refrigeration system reached the steady state operation. The evaluation of the data showed that the coefficient of performance of the refrigerator was degraded by about 17.6%. This value, of course, may seem to be very high in terms of performance, but it is based on the compression work not the input power to the compressor. Unfortunately, home users who have a refrigerator with a capacitor will not be able to save money, in contrast they will pay more since the only active power is measured at homes, but utilities, on the other hand, will start saving money because of the reduced total power demand.
