Parametric study of induced draft counter flow rectangular cooling tower based on exergy analysis

摘要

This study presents development of a simple and efficient mathematical model, in which energy, draft and pressure equations are solved simultaneously. Model was validated with experimental data collected from an induced draft counter flow rectangular cooling tower of a refrigeration plant (capacity, 220 tonnes) in a dairy industry at Ambala (India). Model predictions and experimental data match satisfactorily. In a parametric study, wet bulb temperature of inlet air plays a significant role on air and water outlet temperatures, evaporation loss, fan power, thermal efficiency, exergy destruction and second law efficiency.
