WebFor the Carnot cycle, or its equivalent, the average value TH will equal the highest temperature available, namely TH, and TC the lowest, namely TC. For other less efficient thermodynamic cycles, TH will be lower than TH, and TC will be higher than TC. WebNov 29, 2012 · The COP for the refrigerator is output/input where the output is the amount of heat removed from the cold reservoir, Qc and W is the work supplied: COP = Qc/W Since W = Qh-Qc, and Th/Tc = Qh/Qc, you can express COP in terms of Th and Tc (your expression is correct). For a) what do you need to find? (hint: it is one of W, Qh or Qc).

WebAnd we showed that for an engine, that could also be rewritten as 1 minus Q2 over Q1, or essentially, 1 minus the heat we output from our engine divided by the amount of heat we input from our engine. Now we applied this formula to a Carnot cycle, and we said, hey, for a Carnot engine, we could get an efficiency of this. harbor leasingWebA refrigerator or heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump, and their COPs are COP TT T TT COP TT T TT R Carnot HL L HL HP Carnot LH H HL / / = − = − = − = − 1 1 1 1 Notice that a turbine is used for the expansion process between the high and low-temperatures. harbor lending grouphttp://labman.phys.utk.edu/phys136core/modules/m3/refrigerators.html harbor leaseWebThe coefficient of performance (COP) of the heat pump is defined as the ratio of the amount of heat provided to the required work.
