  • Actual room air conditioner usage in the residential sector of Japan : 2nd report : Cluster analysis and determination of the operating ratio functions

    　View Summary

    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.

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. After analyzing the obtained data, two types of operating ratios were introduced—an outdoor-temperature-associated operating ratio (TOR) and an hour-associated operating ratio (HOR). It was found that there is essentially little difference in the TOR and the HOR among the monitored sections or the monitored months in the same season from the standpoint of the sectional or monthly average. We also performed a simple questionnaire survey and compared to the measured data.

    　View Summary

    The performance of an air dehumidification system with lithium chloride solution used as a desiccant was studied experimentally. First, the mass-transfer coefficients were measured for a structured packed dehumidifier/regenerator. It was shown that the overall mass-transfer coefficients varied from 2.5 to 7.8 g/(m2·s) when the air velocity was increased from 0.5 to 1.5 m/s in the dehumidifier and varied from 1.2 to 2.7 g/(m2·s) in the regenerator. Second, experiments on the air dehumidification system were conducted. The experimental results showed that higher humidity in summer and lower humidity in winter resulted in decreased dehumidifying (humidifying) efficiency.
