Automated energy-saving reconstruction design of industrial cooling water system
The cooling water system of a certain enterprise is often subject to energy waste due to manual control in the background.By analyzing the cooling limits of cooling towers and energy-saving measures for water pumps,the load rate of the cooling tower is controlled at 50%,and the start and stop of the motor are judged in combination with the wet bulb temperature.the water pump adopts synchronous frequency,the bypass valve actuator is replaced with a regulating type to avoid the occurrence of high flow at low temperatures in winter.The PID tuning parameters of constant pressure water supply and con-stant flow control is set by Lambda algorithm.Under the premise of not affecting the system,this renova-tion can achieve zero operation,after 7 months of stable operation,power consumption was 43,716 kWh lower than the same period last year.
