The present work deals with an experimental analysis of the performance of a direct expansion coil under various operating conditions. Behaviour of the cooling coil vis-à-vis the input parameters and the psychrometric properties is assessed with the help of experimentation with changing ambient conditions and graphical presentation of the results. Results depict an optimum value of the by-pass factor indicating the best performance of the coil in both spring and summer. There is an upward trend of the by-pass factor with a gradual rise in the air temperature at different inlet openings. Dependence of the cooling coil performance on volume flow rate and climatic variation is found to be quite significant and needs to be kept in mind in practice.
