摘　　要：本文对医院建筑中空调系统的高区冷冻水侧大温差系统进行全面的技术参数及实际能耗进行分析,通过比较大温差对于风机盘管的影响,发现当医院建筑运行系统提供冷冻水供回水的温差为6℃~7℃时,最能提升空调系统的经济效益与节能潜力。经研究,冷冻水大温差技术的“小流量、大温差”能够达到降低能耗、减少运行成本的目的。This article comprehensively analyzed the technical parameters and actual energy consumption of the large temperature difference system on the chilled water side of the high area air conditioning system in hospital.The“small flow,large temperature difference”technology of the large temperature difference in chilled water can achieve the goal of reducing energy consumption and operating costs.This article compared the impact of large temperature differences on fan coil units,summarized the relevant practical experience and improvement measures of large temperature difference energy-saving technology,which concludes that the optimal temperature difference reference value for chilled water supply and return water in hospital buildings is 6℃~7℃,which can improve the economic benefits and energy-saving potential of air conditioning systems.
