Abstract
Air conditioning design has become an interesting aspect of human life with the aim of seeking environmental comfort for indoor spaces. Analytical work involves in the design of air-conditioning system is often time consuming and laborious. This work therefore aims at developing a visual interactive computer package for the design of air conditioning system using the international conference centre, University of Ibadan, Nigeria as a case study. Procedures for calculating heat gain through various building components were discussed in detail. Cooling load analysis was carried out using standard cooling load equations obtained from the American Society of Heating, Refrigeration and Air conditioning Engineers (ASHRAE) handbook. A computer program was developed using java programming language to compute the total cooling load in the building. The result from the computer program was obtained within a very short period of time when compared with that of the manual one. The cooling load of the building obtained was 3,194,414 btu/hr; a visual interactive computer package for the design of air conditioning system has been developed and tested positively; hence can be used to design air conditioning system for any building.

Cooling load analysis was carried out using standard cooling load equations obtained from the American Society of Heating, Refrigeration and Air conditioning Engineers (ASHRAE) handbook
For large and complex air conditioning systems, there is no substitute for a painstaking engineering analysis
Summary
It is of great necessity that the available data is accurate if a high degree of accuracy of land estimation is required To provide this database, a detailed survey of an existing building or of the plans for a new building is essential factors such as construction materials, orientation of the building [2] [3], occupancy of peak and off-peak conditions, cedes and government regulations together with preliminary consideration of type of system or unit are all important to the load calculation. This project has made design of air conditioning system easier, faster and readily available when compared with the existing other computer programmes in the local market
