It is important to evaluate the annual performance factor (APF) of room air conditioners (RACs) in accordance with their actual usage in residential sectors. In this study, actual RAC usage was monitored for 100 families over a year by equipping each air conditioner with an electric power meter and a data logger. We monitored 25 families living in detached houses in the Shinetsu area (a cold area), 25 families in the west Kanto area, 25 families in the east Kanto area, and 25 families living in apartments in the east Kanto area. In this report, we showed the results of a cluster analysis on an outdoor-temperature-associated operating ratio (TOR) and an hour-associated operating ratio (HOR), and the most influential operation pattern for the total operating time was ascertained. Finally, an appropriate and simple method for obtaining the APF of actual RAC usage is outlined.
