Question:
In absorption refrigerators the energy driving the process is supplied not as work, but as heat from a gas flame at a temperature τhh > τh. Mobile home and cabin refrigerators may be of this type, with propane fuel.
(a) Give an energy-entropy flow diagram similar to figures for such a refrigerator, involving no work at all, but with energy and entropy flows at the three temperatures τhh > τh > τl.
(b) Calculate the ratio Ql/Qhh, for the heat extracted at τ = τl, where Qhh is the heat input at τ = τhh. Assume reversible operation.
