This thesis involved experimental tests to determine the influence of humidity of ambient air on the performance of a given air conditioning cooling system. The effect of the moisture content of the ambient air is investigated experimentally, the work being carried out on a standard equipment, the Hilton air conditioning laboratory unit. Results obtained indicate that the cooling coil performed better with decreasing ambient air moisture content. The efficiency of the cooling coil was about 90% when the ambient air temperature was lower, while at high ambient air temperature the performance rating of the cooling coil was between 40 to 50%. Under this condition the coil would start frosting continually while in use. It was found that the log mean temperature difference of the cooling coil decreased with increasing ambient air moisture content. Conclusively, cooling coil of air conditioner operating under humid conditions are likely to perform better when they operate under less humid condition.
