Abstract
Performance of the coolig tower was analysed with various operating parameters and find the minimum cold water temperature. In this study, optimization of operating parameters was investigated. An experimental design was carried out based on central composite design(CCD) with response surface methodology(RSM). This paper presents optimum operating parameters and the minimum cold water temperature using RSM method. The RSM was used to evaluate the effects of operating variables and their interaction towards the attainment of their optimum conditions. Based on statistical analysis, water flow, air flow, hot water temperature and packing height were high significant on cold water temperature, with very low probability values(<0.0001). The optimum operating parameters predicted using RSM method and confirmed through experiment.
Highlights
The cooling tower is a steady flow device that uses a combination of mass and energy transfer to cool water by exposing it as an extended surface to the atmosphere
Simpson and Sherwood studied the performance of forced draft cooling towers with a 1.05 m packing height consisting of wood slats [2]
Many parameters affecting the performance of counter flow wet cooling towers are investigated
Summary
The cooling tower is a steady flow device that uses a combination of mass and energy transfer to cool water by exposing it as an extended surface to the atmosphere. The water surface is extended by filling, which presents a film surface or creates droplets. Air is moved by one or more mechanically driven fans to provide a constant air flow. Strength and composition guard against common cooling tower problems resulting from fire, chemical water treatment and deterioration. The operating theory of cooling towers was first suggested by Walker [1]. Simpson and Sherwood studied the performance of forced draft cooling towers with a 1.05 m packing height consisting of wood slats [2]
