In this paper, the heat transfer theory and the characteristic of structure and technique for evaporative condenser are analyzed. A mathematical model for economical-technical analysis based on the investment-economics theory and its analyzing methods has been established and applied to analyze and calculate the economical properties of refrigerating device with different type of condensers. The result shows that the refrigerating device, which uses evaporative condenser can reduce its running expenses by a wide margin, and indirectly get a large yield of investment. The model suggests a good way for us to evaluate and analyze the projects of investment and design.
