| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 94 === In Green Building Evaluation Indexes, the EAC has been adapted as the central HVAC system energy consumption criteria, has been assigned an energy saving factorα4 of 0.2, despite of the actual power consumption variations existed among various system.
In this study, the PILV values of specific VRV systems were utilized, so that actual energy-saving factor α4 can be evaluated. Furthermore, being lack of the chilled water distribution system, the weighting of power consumption percentages of a VRV system has also been changed into 0.9 vs. 0.1 for the outdoor and indoor units respectively.
The methodology established in this study has been justified by suing the actual VRV projects under commercial operations, which can successfully discriminate different energy efficiencies among various systems.
