1、山东农业大学水利土木学院毕业设计说明书题目：南京市某行政办公楼地源热泵空调设计作者：李述龙学号：20093219院系：水土学院专业：建筑环境与设备工程专业班级：09年级三班指导者：刘小春老师2013年6月毕业设计（论文）中文摘要南京市某行政办公楼地源热泵工程设计某办公楼，共六层，地处江苏南京市，全楼采用地源热泵系统进行集中供给空调方式。该中央空调集中系统采用风机盘管加独立新风系统，而水系统采用半封闭式螺杆机组，为闭式双管异程式。空调主机使用型号为LRY-L460一台制冷量462.7Kw,空调侧使用两台型号为IS80-65-160循环水泵，功率7.

2、5Kw，地源侧使用两台型号为IS80-65-160循环水泵，功率为7.5Kw，机房设置在地下室，节约了建筑面积。关键词办公楼地源热泵热平衡地下换热器集分水器目次引言·························································11、设计依据1.1设计任务书···················································61.2建筑平面剖面图···············································61.3设计参数·····
