Abstract: This paper present the design of a central air-conditioning /ducting system for a case study of a University Senate Chamber in Nigeria. The design aims at maintaining conditions that are conducive to human comfort within the senate chamber of the University. (24°C - 25.5°C, 50% - 55% RH). The design month was March (6) and using the expert assistance found in the carrier system design ducting analysis manual the refrigeration tonnage obtained was 40 and the total air quantity required to remove the heat load was 9908cfm. Low velocity with equal friction method was used in the ducting analysis. Equipment selection was carried out for the proposed system. A simulation was carried on the proposed system to estimate the relative humidity and temperature at various times. Another test was carried out on the actual (existing unit) to estimate relative humidity and temperature at various times and positions within the chamber. A comparison of the simulated and tested values with standard comfort conditions reveals that the new design will certainly give more comfort.
