Abstract：In order to reduce the energy consumption of air conditioning water system and improve the energy efficiency of refrigeration room,the energy-saving optimization of refrigeration room system was studied.Taking an office building in Qingdao as the research object,Trnsys software was used to build a simulation platform for central air conditioning water system.The energy-saving effects of three optimization schemes,namely the application of permanent magnet synchronous motor,synchronous frequency conversion operation of parallel water pump and parallel operation of cooling tower,were explored,and the overall optimization of central air conditioning water system was analyzed on this basis.The results show that after optimization,the operating energy efficiency of the refrigeration room is increased by 17％,and the average energy efficiency ratio(EER)of the refrigeration room is up to 5.6,which can effectively reduce the energy consumption of the building.
