PURPOSE:To reduce the load working ratio of the air conditioner and to save energy by a method wherein the load operation ON-OFF time is corrected according to a predetermined night cycle setting table to thereby perform the load operation at night. CONSTITUTION:An ON-OFF duty setting table and the night cycle setting table are housed in RAM by means of an operation control section. The output of a thermosensor is inputted to a microprocessor from an input device so that an ON-OFF pattern is determined by the ON-OFF dutysetting table in RAM and a clock generating circuit to thereby turn the load on and off. In this case, when an operation control device judges that a night cycle correcting timing is due at night on the base of the night cycle setting table in RAM, the OFF time is extended on the base of an OFF time extension pattern of the duty setting table. Thus it is possible to save energy by extending the OFF time at night. |
