Abstract
petitiveness and success of the manufacturing organisation. The analytical hierarchy process (AHP) is an important tool to solve MCDM problems. The choosing process of suitable material (such as a refrigerant fluid) for the Air Condition System (ACS) is faced with challenges such as lack of a systematic approach in setting the optimal performance in terms of its impact on the environment and operation. Selecting process for the one refrigerant from a range suitable of suitable refrigerant is complex process. The study presents a comparative performance analysis of ACS for using four alternative refrigerants R290, R410, R404 and R22. Then, one of these suitable refrigerant is selected. The comparison is based on three criteria system operation, environment and maintenance. Novels ACS performance assessment model is proposed based on an analytical hierarchy process (AHP). The model is based on two main criteria of ACS, quantitative criteria, cooling capacity (CC), coefficient of performance (COP), etc.).
