STORAGE BATTERY TYPE AIR CONDITIONING APPARATUS

摘要

PROBLEM TO BE SOLVED: To simplify the construction of an apparatus by eliminating unnecessary functions in a storage battery type air conditioning apparatus. SOLUTION: A charge/discharge controller 70 is integrally provided on a storage battery unit of a storage battery type air conditioning apparatus. The charge/discharge controller 70 includes an RTC circuit 91 and a zero cross detection circuit 93 both provided thereon. A time correction section 76 and a schedule instruction section 77 are provided on a CPU 71 in the charge/ discharge controller 70. The time correction section 76 counts zero crosses of voltage of commercial electric power detected by the zero cross detection circuit 93, and based upon this it corrects the time counted by the RTC circuit 91. Charge/discharge operation for the storage cell is performed following the correct time obtained by the time correction section 76 and a charge/discharge schedule held in the schedule instruction section 77.
