The invention relates to an intelligent
electricity-saving control method for cooling towers in a central air-conditioner
monitoring system. The intelligent
electricity-saving control method is designed to solving the technical problem that in existing central air-conditioner monitoring systems, design of intelligent
electricity-saving control methods for cooling towers is in lack of convenience. The intelligent electricity-saving control method is mainly characterized in that a temperature sensor on a
pipe arranged between a cooling pump and a cooling water
inlet valve of a
refrigeration main
machine is a cooling water returning temperature sensor; the cooling water returning temperature sensor is connected with temperature sensors at three positions, namely the temperature sensor arranged at the cooling water outlet position of water outlet of the
refrigeration main
machine, the temperature sensor arranged at the position where a
cooling temperature difference of water inlet of the
refrigeration main
machine is generated and the temperature sensor arranged at the position where a
cooling temperature difference of water outlet of the cooling pump is generated; two
modes, namely the automatic mode and the intelligent
modes, are arranged for the cooling water returning temperature sensor, and thus in the specific operation process of a central air-conditioner, by means of an intelligent
algorithm in which the cooling towers are
cut away, manual control over the number of the cooling towers is achieved; and by means of a touch screen end of
cooling tower equipment, real-time monitoring is conducted, a real-time online
sorting algorithm is adopted for
operation time of the cooling towers, a time balanced control strategy is guaranteed, and for each time, the
cooling tower which runs for the longest time is started and the tooling
tower which runs for the shortest time is switched off.
