Abstract

Selection of cooling systems based upon the traditional definition of the coefficient of performance (COP) may create misleading results because it does not consider all factors affecting the selection . A multi-attribute decision analysis is necessary to differentiate between various air conditioning cooling systems for arid zones. The Kingdom of Saudi Arabia is chosen to be the case study and seven main criteria, which include twenty subcriteria are selected. To carry out such analysis, an Interactive Fuzzy Decision Analysis Computer Package (IFDA) is used. This package utilizes verbal rating, weights for each attribute and sub attribute as Input, IFDA is based on Fuzzy Set theory. The results show that the Li Br absorption dual system is the best air conditioning cooling system to be used in Saudi Arabia and the ammonia water absorption system is the second best.
