| Abstract: | Exergy transfer unit is the basic cell of exergy transfer model. Nine characteristic rules of three kinds for exergy transfer unit were put forward in this paper. The characteristic rules for eight typical exergy transfer units of three kinds of exergy transfer including heat transfer, energy conversion and mass transfer were studied and the relative calculating formula or expression were presented. These may provide a basis for standardizing the construction of elementary engineering exergy transfer model and simplifying the engineering exergy transfer analysis of the complicated systems. |
