Abstract
In recent years, the penetration of air conditioners and office automation facilities increase the electric power demand disparities among seasons and even for daytime and nighttime uses in Japan. Thus, the ice thermal storage air conditioners have been rapidly spreading to level the annual power load. Also, the needs of the HFC refrigerant, which has zero ozone depletion potential, are increasing from a viewpoint of ozone layer protection. The ice thermal storage multi-split system air conditioner utilizing the HFC refrigerant, R407C, has been developed to contribute power load-leveling and energy saving. In this paper, the technical features of the new ice thermal storage multi-split system air conditioner are clarified.
