Abstract：Taking a certain metro station in Shenzhen as the research object,data on load,operation mode,control strategy,energy consumption,etc.are collected and deeply analyzed by using self-developed patented software.Based on the characteristic curve of the air conditioning main unit,according to the load changes and temperature requirements,combined with the full frequency conversion control system and platform simulation prediction,the comprehensive method of adjusting the strategy in real time is adopted to improve the energy efficiency of the system.The results show that the full frequency conversion improves the energy efficiency by 11%compared with the frequency conversion of the chilled water pump alone.The inlet and outlet water temperatures on the cooling side are reduced by 1℃,and the energy efficiency is enhanced by 3.7%.
