| Abstract: | Through analyzing the constitution of condenser of centrifugal chillers,calculated the velocity of flow of cooling water by the pressure difference of cooling water in tube in accordance with Kern equation of shell and tube heat exchanger, then acquired the heat transfer coefficient of the condenser, finally, got out the condenser heat load and refrigeration capacity of centrifugal chillers. Established the relationship between the pressure difference of cooling water and refrigeration capacity of centrifugal chillers. It's benefity to design and control of centrifugal chillers. |
