Abstract
An energy-saving optimized control system for a chiller plant room comprises an industry control computer, a flow sensor, a temperature sensor, an outdoor temperature and humidity sensor, a three-phase active power transmitter, a water pump variable speed driver and a cooling tower fan variable speed driver, which are respectively connected with a programmable controller, wherein the programmable controller communicates with the industrial control computer through an industrial Ethernet; and an RS485 communication interface module is connected with chillers and communicates with the industrial control computer through a ModBus protocol. An energy-saving optimized control method for a chiller plant room is also provided. By establishing a mathematical model of the relationship between the energy consumption and operation parameters of each equipment in the refrigeration plant room and combining the real-time cooling loads and weather parameters, the operating state of each equipment is adjusted so as to reach the lowest operating energy consumption of the whole chiller plant room under the premise of meeting the cooling loads.
