摘要
In this paper,temperature difference field (TDF) has been studied in multi-pressure condenser. Analytical results show that there is a certain liner relationship between the nonuniformity factor of TDF and the mean condensing temperature. With the nonuniformity factor of TDF, the optimization is made for the distribution of heat transfer capacity and area in different steps of multi-pressure condenser. The validity of the uniformity priciple of TDF is proved in multi-pressure condenser.
