Abstract:
Based on the theory of heat and mass transfer for film type cooling, a mathematical model for the velocity distribution of a thin water film, the equations of mass and heat transfer, and evaporation cooling controlled by the latent heat transfer were established. Combined with the climatic conditions, chiller load and operating conditions at specific times duration, the coefficient of performance, the equations of mass and heat transfer, and the parameter of cooling water and air were tested and calculated. The influence of tower performance on phenomena of drift back mixing and parallel operation of the cooling tower was analyzed. The psychrometric analysis was used to analyse heat and mass transfer process in which the latent heat transfer was predominant. Results show that the evaporative cooling efficiency and effectiveness were the same parameter for cooling tower performance.
