Carnot cop vs actual cop

Answer (1 of 2): Carnot efficiency is greater than Brayton efficiency. carnot efficiency is simply 1- (Tl/Th). here Tl is temperature of the sink and Th is temp of the source. A heat pump working on a reversed Carnot cycle has a CoP of 4. It is made to work as refrigerator with 1 kW work input. The refrigerating effect will be. Q5. The actual efficiency is 96% of the Carnot efficiency, which is much higher than the best-ever achieved of about 70%, so her scheme is likely to be fraudulent. 9. The Carnot Cycle is one of the most widely used ideal and reversible cycles. It is stated that nothing in real life can be more efficient then the Carnot Cycle. Basically the Carnot Cycle is a theoretical heat engine that has two Isothermal processes and two adiabatic processes. It is typically represented by a piston that is in a quasistatic. The Carnot cycle is a reversible cycle and is therefore the most efficient.

Figure 5: Actual Refrigeration Cycle Figure 6: Actual Refrigeration Cycle The Carnot·cycl~ COP is defmed as Tt/(T2-Tt) and in the case ofthe ideal reversed Camot cycle there is no question as to which temperature is Tt and which temperature is T2 but this is not the case, in the actual cycle. Carnot pondered the idea of maximum efficiency in a heat engine questioning whether or not the efficiency of a heat engine can approach 100%, or is there an upper limit that cannot be. A decrease in T LIFT from 21.5 to 18.5 K results in a 11.3% increase in COP (from 7.5 to 8.35), while the Carnot efficiency remains relatively constant (0.54-0.56). Answer (1 of 2): Carnot efficiency is greater than Brayton efficiency. carnot efficiency is simply 1- (Tl/Th). here Tl is temperature of the sink and Th is temp of the source.
