Paper Details

In absorption refrigerators the energy driving the process is supplied not as work, but as heat from a gas flame at a temperature ?hh > ?h. 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 ?hh > ?h > ?l.
(b) Calculate the ratio Ql/Qhh, for the heat extracted at ? = ?l, where Qhh is the heat input at ? = ?hh. Assume reversible operation.
