CARNOT COMPARISON OF MULTITEMPERATURE LEVEL ABSORPTION HEAT CYCLES

Comparison of different absorption heat cycles is not always made in t he correct manner. This also includes comparison of an ideal absorptio n cycle with a mechanical analogy. A new Carnot model operating with t wo heat engines and two mechanical heat pumps is defined to be the cor rect and logical way to describe the mechanical analogy for an absorpt ion heat pump and an absorption heat transformer. General equations fo r the Carnot coefficient of performance, COP(r), are exemplified and s imulated for an absorption heat pump and an absorption heat transforme r, and an entropy flow fraction diagram is introduced. The important f act that the absorption heat cycles must operate under the same condit ions when they are compared is discussed.
