要約(英語): A method is proposed for quantifying the performance of air conditioning systems by using data recorded by a typical energy management system (EMS). An EMS measures the cumulative energy consumption, instantaneous flow amount, temperature of the heat medium, and environmental air conditions, and it typically keeps a record every 1 hour or so. This makes it difficult to quantify system efficiency from these values. The proposed method derives an efficiency value from the distribution shape pattern of the data calculated from these inconsistent data. Applying the proposed method to the data of a site, it produced more stabile results than did the pre-existing method usually applied to business performance analysis. Using 1-min. sampling data, we show that the proposed method extracted the characteristics related to static operation.
