Refrigeration formulas cop
WebIn a refrigeration cycle, the desired output is Q C, because the goal is to remove heat from the cold reservoir. The required input is the work input, W ref. So, COP R = Q C over W ref. Next we use the 1st Law to eliminate Wref from the equation. The result is a useful equation for calculating the COP R. WebThe design is to be based upon the ideal vapor-compression refrigeration cycle, with four components: a cooler (where we reject the heat), a throttle, a heater (where we absorb the heat), and a compressor. Basics of Vapor-Compression …
