A cooling coil is an integral part of an air-conditioning system. Chilled fluid flows through the coil and the incoming air gets cooled and dehumidified as it comes in contact with the coil. However, a portion of the incoming air bypasses the coil and that, in turn, results in the final psychometric condition of the air. In this paper, experiments are performed to quantify the cooling coil performance under changing conditions. Change in weather plays a significant role in influencing the performance of the coil. The effect of the change in inlet opening is also important. A thorough investigation through regular experimentation is done to measure the variability in performance. A multivariate nonlinear regression analysis is done to see the relation of the coil performance to the input variables. The results indicate an ascending trend of bypass factor with a gradual rise in the air temperature at different inlet openings. Besides, the dependence of the coil performance on moist air properties, e.g., relative humidity, is also analyzed. Moreover, higher values of air velocity uplift the bypass factor, indicating lesser capability of cooling.
Evaporators, often termed as chillers, are an integral part of refrigerating systems. They absorb heat from the ambient air in order to produce the required chilling effect. Chillers are often found carrying refrigerant through tubes and called dry
