摘要
本工程地处湖南省益阳市,包括48栋住宅和1栋办公楼。在对建筑冷负荷特点进行分析的基础上,给出了3种夏季空调方案,分别以螺杆式制冷机组、风冷热泵和直燃式溴化锂冷水机组作为空调系统的冷源。通过对方案的初投资和运行费用等进行分析,得出螺杆式制冷机组适合作为本工程的冷源。
The base is located in Yiyang city, Hunan province, including 48 residential buildings and a 19-story office building. Based on the analysis of the profile of building cooling loads, three cooling schemes are put forward, in which screw chillers, air-source heat pump and direct-fired LiBr absorption chillers are adopted as cooling sources for the air-conditioning system, respectively. Compared from initial investment and operating cost, etc, screw chillers are proved more economical than others, and are adopted as cooling sources for this project.
