Abstract
PURPOSE: To improve overall energy utilizing efficiency of a freezing air conditioner, by driving AC motor directly by commercial power source at the time of extended freezing operation of the air conditioner.
CONSTITUTION: Characteristics of control system is designed such that frequency information of output of conversion frequency controlling circuit 17 and output of capacity controlling circuit 16 determined by information of temperature, humidity, etc. is substantially equal to the frequency of AC power source 11. Therefore, while the freezing system is operated under a rated freezing capacity, output frequency information of control circuit 17 and that of revolutional speed detecting circuit 21 are respectively substantially equal to the power source frequency, so that judgement condition of judging circuit 22 is satisfied and judgement output is produced. Resultantly, changeover switches S1, S2 provided respectively between frequency converter 14 and AC power source and between frequency converter 14 and motor 15 are controlled to drive motor 15 directly by AC power source.
