According to CNS-3615, the air-conditioner performance''s usually express energy efficiency ratio (energy efficiency ratio, EER). But the performance indicator utilizes the first law of thermodynamics to establish, and it can represent whole efficiency of the refrigeration system. Towards package air conditioner development process in, the energy efficiency ratio must be to obey CNS-3615, so designers often go to change component’s design, but can only know refrigerating system whole efficiency, unable to go to understand and improve increasing the benefit to energy efficiency of component, and offer the clear direction, where the component is set about. Therefore the main research purposes of this study is developing an exergy analysis mode for system component’s energy efficiency of Water-Cooled Package Air Conditioner. The control volume and boundary temperature will be discuss exergy destruction, exergy efficiency and its proportion affection. Final, use three groups of experience case verify to establish mode''s applicability, bring up by means of by exergy analysis as consultation Water-Cooled Air-Conditioner system component energy efficiency ameliorate effect feasibility. The results show : Water-Cooled type air-conditioner can use Model-3 exergy analysis and control volume contains element, refrigerating side, air side, and cooling water side. The boundary temperature directly adopt environmental temperature is more convenience to analyze. All experience case show the evaporator’s exergy destruction will be the biggest, secondly is compressor, thirdly is condenser, finally is expansion device; The evaporator’s exergy efficiency is the smallest, secondly is compressor, thirdly is condenser, finally is expansion device. This study conclusion will supply Water-Cooled type air-conditioner designer and developer towards to promote energy efficiency and to do ameliorate diagnostic tool that should to improve component’s energy efficiency from exergy destruction is the biggest and exergy efficiency lowest.

Therefore the main research purposes of this study is developing an exergy analysis mode for system component’s energy efficiency of Water-Cooled Package Air Conditioner.
