Refrigerator coefficient of performance
WebSo we replace the coefficient of performance for a heat pump with 1 minus T c over T h to the negative 1 all minus 1 and then plug in numbers. So we have 1 minus 243.15 Kelvin divided by 318.15 Kelvin all to the negative 1 minus 1 and that's 3.24 is the best coefficient of performance you can have for this refrigerator. WebThe coefficient of performance for a refrigerator can be : Medium. View solution > A refrigerator has a coefficient of performance of 1. 6. How much work must be supplied to this refrigerator for it to reject 1 0 0 0 k J of heat? Medium. View solution > A refrigerator absorbs 2 0 0 0 c a l of heat from ice trays.

The coefficient of performance of a vapour compression refrigeration system operating on R- with SSTO and inclusion of SiO 290 has been improved by 15.9% by including a stepped short tube orifice. This performance coefficient is greater than the performance coefficient
WebSince the ratio of heat removed to work input is defined as the coefficient of performance (COP) of a refrigerator, this corresponds to a COP of 1.8. This relatively low COP of the Carnot refrigerator used for natural gas liquefaction is expected due to high difference between the temperatures T and T0 in Eq. (14.31). Web10 J of work are done per cycle on a refrigerator with a coefficient of performance of 5.0. How much heat is extracted from the cold reservoir per cycle? Express your answer using two significant figures. How much heat is exhausted to the hot reservoir per cycle? Express your answer using two significant figures.
