ABSTRACT:
A high-efficiency, compact and low-cost electric power storage air-conditioning system incorporates inside its air-conditioner an electric power storage unit including a battery which is electrically interconnected to a d.c. system of the air-conditioner. Charging of the battery is controlled to be executed only during a steady operation of the air-conditioner when its load is light. Since a d.c. voltage of the battery is used directly as a d.c. voltage to drive the air-conditioner, a high efficiency, minimized loss and economical operation conditioning system is achieved.
