Dalian a hospital ground source heat pump air conditioning system design

本文介绍大连市某医院地源热泵空调系统设计。经过对空调系统冷热源方案的对比优选和岩土热响应实验,确定该项目采用地源热泵空调系统。本工程地层分布以岩石为主,且地下水位较高,出水量较大。本次实验研究仅计算出冬季、夏季单位埋深地埋管换热器的取热量,为地埋管地源热泵系统的详细设计提供参考。由于本工程可利用面积较紧张,室外地埋管采用竖向单U形管埋管形式。针对大连地区无市政热网的公建项目,简要分析地源热泵空调系统的经济性,并对地源热泵空调系统在设计、施工中常见问题进行总结和分析。

This paper introduces ground source heat pump air conditioning system of some hospital in Dalian. Through the comparison of cold and heat source scheme optimization of air conditioning system and thermal corresponding test, the project determined the ground source heat pump air conditioning system. The rock is the major material in this project, with high underground water level and plenty of water. This experiment study only calculate the heat of one meter ground heat exchanger in winter and summer, providing the reference to the detail design of buried pipe ground source heat pump system. Because the area of this project is not enough, the buried tube outdoor uses vertical single u-tube forms. For the public project without municipal heat supply network in Dalian, the text briefly analyzes the economics of ground source heat pump air conditioning system, and summarizes the common problems in the design and construction.
