定西市某商业综合体暖通空调设计冷热源方案比选

Comparison and selection of cold and heat source schemes for HVAC design of a commercial complex in Dingxi city

利用定西市已有条件,制定4种不同的空调冷热源方案,通过方案比选方法比较分析各方案的初投资及运行费用,选出适合本项目商业综合体的空调设计冷热源方案。研究表明,在已有的条件下,冷热源采用水冷式冷水机组+市政热源初投资及运行费用最低,为本项目最优解。研究为西北地区商业综合体的冷热源选取提供参考。

Based on the existing conditions in Dingxi City,four different air-conditioning cold and heat source schemes are formulated,and the initial investment and operation cost of each scheme are compared and analyzed by scheme comparison method,and the air-conditioning design cold and heat source scheme suitable for the commercial complex of this project is selected.The research shows that under the existing conditions,the initial investment and operation cost of water-cooled chillers+municipal heat sources are the lowest,which is the optimal solution of this project and provides a reference for the selection of cold and heat sources of commercial complexes in Northwest China.
