Consider the steady operation of a different self-contained refrigeration "package" for a shipping container. The device is thermally activated by heat transfer from a steady 2000 oF external source. The external thermal source is due to complete external combustion of the propane fuel. Assume all of the fuel energy is input into the device. The device absorbs 5 kJ/s of heat transfer from a -20 oF shipping container and rejects 9 kJ/s of waste heat to the +59 oF atmosphere. Determine the actual COP of this "thermally-activated refrigeration package" cycle = useful energy effect/expensive energy input. Also determine the maximum reversible COP and the theoretical minimum fuel energy input required to provide a 5 kJ/s cooling effect. Notice external work is zero; and that for a reversible cycle, (Q/T)REV = 0 (using sign convention QIN >0 and Qout<0) Calculate the cycle COP. Compare to the maximum reversible COP and minimum input needed.
