Development of Automatic Constant Pressure Water Replenishing Device for Chilled Water System
Chiller units are a crucial component of air conditioning systems,and chilled water consumption varies over time,necessitating a water replenishment system to maintain stability.For the chilled water replenishment system of our company,automatic control is achieved through PLC programming and frequency converters.The PLC collects pressure data from the main pipeline,processes it through the CPU and communicates with the human-machine interface,then outputs a water replenishment signal to the frequency converter to control the water pump motor for water replenishment.An automatic constant pressure water replenishment device has been developed to achieve safe and stable water replenishment functions,and its usage is statistically analyzed.
