WebSep 12, 2024 · The effectiveness or coefficient of performance K R of a refrigerator is measured by the heat removed from the cold reservoir divided by the work done by the working substance cycle by cycle: (4.4.1) K R = Q c W = Q c Q h − Q c. Note that we have used the condition of energy conservation, W = Q h − Q c, in the final step of this expression. WebPerformance of a refrigeration cycle is usually described by a coefficient of performance (COP), defined as the benefit of the cycle (amount of heat removed) divided by the required energy input to operate the cycle: Chapter 2 describes several methods of calculating refrigerant performance, and … V alues in the following tables are in consistent units to assist the engineer lookin…
WebMay 15, 2014 · The basic transcritical CO2 systems exhibit low energy efficiency due to their large throttling loss. Replacing the throttle valve with an ejector is an effective measure for recovering some of the energy lost in the expansion process.
