This paper analyzes the influence of air accumulation on the heat transfer of condenser, introduces the determination method of dry air in condenser, elaborates the thermodynamic calculation method of condenser and the solution of condensation volume in heat exchange zone. Based on the calculation of air volume in each heat exchange zone and the total air values recommended by HEI, the dry air distribution in each heat exchange area is calculated. It provides data support for the design of air extraction tube of condenser, strengthens heat transfer performance and improves the economy of condenser.
