Refrigeration is a process of eliminating heat from a low temperature reservoir and ... E HAJIDAVALLOO et al. [5] , in this paper to reduce the challenging problem of increase of ... Weblubricant increases the coefficient of performance to 19.19%, compared to the vapour refrigeration system without stepped short tube aperture. After all calculations are completed, it is noticed that the net refrigeration effect is enhanced while the compressor effort is lowered, therefore increasing the coefficient of performance. CONCLUSION ...
WebCoefficient of Performance of a Refrigerator: The performance of a refrigeration system is expressed by a term known as the coefficient of performance(C.O.P.) It is the ratio of heat extracted in the refrigerator to the work done on the refrigerant. It is also known as the theoretical coefficient of performance. WebA typical new household refrigerator consumes about 680 kWh of electricity per year and has a coefficient of performance of 1.4. The amount of heat removed by this refrigerator from the refrigerated space per year is (a) 952 MJ/yr (b) 1749 MJ/yr (c) 2448 MJ/yr (d) 3427 MJ/yr (e) 4048 MJ/yr arrow_forward
