Abstract
PURPOSE: To restrain wasteful consumption of electric power by a method wherein a circuit is constituted so that a cooling water pump is operated during a necessary time only and a cooling tower fan is operated only when a temperature of cooling water is increased by timers.
CONSTITUTION: An ordinary air conditioning is effected when beginning and stopping times of a cooling device are set in a 24hr timer TR1. In case of an attendance earlier than usual, a push-button PB1 for the earlier attendance is pushed, thereby, a switch X1' is closed and a relay X1 is operated while a switch X1" is also closed and a relay X2 is operated to operate the device in an ordinary operating condition, thereafter, the operation enters into the operation controlled by the main timer TR1 and is stopped at a time to stop the air conditioning. In case of an overtime working, a timer TR2 for the overtime is set at the overtiming time and a push-button PB2 is pushed, then, a self-holding switch TR2" is closed, the operation is switched to an operation controlled by the timer TR2 and a switch TR2" is closed. Thus, forgetting of stopping the operation may be prevented and electric power is saved by automatic proper operation and stopping of the device necessitated to be operated upon the overtime working and the earlier attendance.
