NUMERICAL ANALYSIS OF THE CONDENSATION CHARACTERISTICS OF DIFFERENT HEAT-TRANSFER MEDIA IN AN AIR-COOLED CONDENSER

摘要

A mathematical model of an air-cooled condenser (ACC) section is developed. It allows comprehensive study of its operation for various geometries, conditions, and heat-transfer media. A software program for numerical analysis of an ACC section developed using Excel spreadsheet software is used to study the dependence of rates, thermal and aerodynamic characteristics of the condensation of a number of heat-transfer media in a standard ACC section on the velocity of the cooling air. The model can be used for design of thermal power plants and refrigerating machines with air-cooled condensers.
