查询词典 cooling by evaporation

The model aims at minimum annual cost (including operating cost and equipment depreciation cost) of whole evaporation system (including two sequential system——multi-evaporation system and multi-level preheating system). The tempreture of flesh vapor, the tempreture of condenser, effective heat-transfer temperature difference of vari-effect, and outlet solution temperature of vari-level preheater were both decision variables.
