摘　　要：通过对医院新建大楼集中式空调系统之高效机房设计进行探讨,提出全年平均能效比(EER)不小于6.0的1级能效等级设计指标,并简要阐述了实现的路径;而在医院既有集中式空调系统运维上,通过采取“智能化、制度化、专业化、精细化”等节能管理举措,使得在医疗业务量大幅增长的情况下,仍旧实现大楼建筑耗电量同比下降约2.66%,每小时用电负荷约减小53kW。通过对医院既有集中式空调系统中能耗占比最高的空调主机进行变频改造仿真计算,发现变频改造后的空调主机能效有望实现较大提升,并实现年节约99545.4度电,节能率约为19.44%,减少二氧化碳排放量约56.77吨。By exploring the efficient machinery-room design of the centralized air conditioning system in a newly built hospital building,the level 1 energy efficiency design indicator with an annual average energy efficiency ratio(EER)of no less than 6.0 is proposed.The path of achieving the efficient machinery-room is explained briefly.By adopting energy-saving management measures such as intelligence,institutionalization,specialization,and refinement,the operation and maintenance management are being performed in the existing centralized air conditioning system of the hospital.The building's electricity consumption has decreased by 2.66% year-on-year,and the hourly electricity load has decreased by 53kW,despite a significant increase in medical business volume.Finally,by simulation calculations on the frequency conversion transformation of central air conditioning unit,which is the highest proportion of energy consumption in the existing centralized air conditioning system of the hospital,it is found that the energy efficiency of the air conditioning unit after frequency conversion transformation is expected to be significantly improved,and an annual energy saving of 99545.4kWh will be achieved,with an energy saving rate of about 19.44% and a reduction of about 56.77tons of carbon dioxide emissions.
