Maximum theoretical cop
WebMaximum Theoretical Efficiency for a Nuclear Reactor A nuclear power reactor has pressurized water at º 300 º C. (Higher temperatures are theoretically possible but practically not, due to limitations with materials used in the reactor.) Heat transfer from this water is a complex process (see Figure 15.22 ). Web15 feb. 2024 · So, maximum theoretical efficiency COP can be calculated as: Heat Pump’s COP = 298K / (298 K – 287 K) is equal to 27.09. Therefore, in theoretical terms, heat …
