基于方案排队法的空调系统冷热源优化布局

冷热源是建筑用空调系统的核心部分，其布局性能直接影响整个空调系统的设计目标和运行效率．基于方案排队法，建立了某空调系统冷热源布局方案的优选模型，对布局模型的各量化指标，采用综合赋权法计算出相应目标参数的权重；对于定性指标，则采用专家调查法进行评价．综合定性和定量分析确定出优选的冷热源布局，结果为方案5最优，这种方法易于理解和实施，为空调系统冷热源布局的设计提供了新途径．

The Optimal Layout of Cooling and Heating Sources of Air-Conditioning Systems Based on Project Queuing Method

Cooling and heating sources are core part of the air-conditioning system in a building,and their layout directly affects designing objective and running efficiency of the whole system. Using project queuing method,we established the optimal model of layout schemes of cooling and heating sources of a certain air- conditioning system. For the quantitative indexes of the layout model ,weight values of corresponding objec- tive parameters were calculated by the overall weight method, and the qualitative indexes were evaluated by the expert investigation approach. Based on the analysis of the above results, we have found the fifth scheme is best ,and the optimal layout of cooling and heating sources is accordingly determined. The case shows that the proposed optimal layout method is easy to understand and follow,and provides a new mode for designing the layout of cooling and heating sources of the air-conditioning system.
