Optimization of ducting system for airconditioning

Abstract

In this study, an attempt has been made to determine the, optimum duct sizes for minimum owning and operating cost (life cycle cost) of an airconditioning ducting system. In this regard, a mathematical model has been developed considering' multipath ducting system. A computer program has also been developed to find the optimum solution of the model. The model has been applied to a specified ducting system. The result of the proposed method has been compared with those of other conventional duct sizing methods for the specified,) ducting system. Comparison shows that the minimum life cycle cost obtained by the proposed method is 9.23 percent and 4.12 percent lower than those obtained by static regain and Equal friction methods respectively.
