医院住院部空调能耗影响因素分析
Impact factors of air conditioning energy consumption in hospital inpatient buildings
摘要：
以上海某医院为例，选取10个影响空调系统能耗的主要因素进行分析，利用eQUEST软件对典型综合住院楼的空调能耗进行了模拟，分析了各因素对空调能耗的影响程度。应用正交试验法得出因素敏感性排序为：室内设计温度>新风量>冷水供回水温差>冷源效率>外墙传热系数>水泵效率>外窗遮阳系数>风机效率>外窗传热系数>照明密度，针对影响程度较大的因素提出了相应的节能措施。
Abstract：
Taking a hospital in Shanghai as an example, selects ten factors impacting the air conditioning system energy consumption, simulates the air conditioning energy consumption of a typical comprehensive inpatient building using eQUEST software, and analyses the influence of various factors on the air conditioning energy consumption. Obtains a sensitivity order of the factors by orthogonal test method, which is indoor air design temperature, outdoor air rate, chilled water temperature difference between supply and return water, efficiency of cold source, heat transfer coefficient of exterior wall, pump efficiency, shading coefficient of exterior window, fan efficiency, heat transfer coefficient of exterior window and lighting density. Proposes the corresponding energy saving measures for the main factors.
