Abstract:

According to the central air-conditioning chiller and cooling water system existing models of power consumption of each equipment,fitting data collected in the experiment, including the system load, water chiller cooling water inlet temperature and flow of cooling water pump and cooling tower fan operation frequency, then establish a cooling water system of the total power general optimization equation. Tool was optimized by using variable metric optimization algorithm of BFGS to calculate the minimum energy consumption under different external conditions, so as to control the cooling water system equipment. Practice utilization illustrates that the method of the research has the characteristics of convenient, energy saving effect significantly.
