能流图在洁净手术部空调设计中的应用
Application of energy flow chart on air conditioning system design for clean operating departments
摘要：
由于对室内环境的要求较高，医院洁净手术部的空调系统能耗比普通区域的空调系统大。为了简化能耗分析，提出一个新的技术经济评价指标——空调能效成本指标ECE，并将其与能流图融合，作为空调能耗的辅助分析工具。利用能流图和ECE分析了建筑布局、换气次数、风机风压、空气处理过程等对手术部空调能耗的影响。建议在设计阶段采用该简便方法对空调方案的能耗和能源费用进行必要的技术经济比较分析。
Abstract：
The energy consumption of air conditioning system in operating rooms is higher than that of other zones in a hospital because of higher indoor environment requirement. In order to simplify energy consumption analysis, puts forward a new technical economical evaluation index, i.e. energy cost effectiveness (ECE) of air conditioning, which is used as an auxiliary analysis tool combined with an energy flow chart. With the energy flow chart and the ECE index, analyses the influence of building layout, air change rate, fan pressure head and air handling process on the energy consumption of air conditioning system for clean operating departments. Suggests that the method be used to make necessary comparison and perform technical and economic analysis for the energy consumption of air conditioning schemes at design phase.
