湖南某湖水源热泵可行性水体调查与方案分析

Feasibility Investigation and Scheme Analysis of Heat Pump for a Lake Water in Hunan

对湖南中北部某湖水水深、水温以及水质进行全面调查并且对湖水源热泵方案实施的可行性进行分析。采用湖水温度预测模型预测湖水自然水温,从而详细计算该地区夏季工况湖水热承载能力。提出三种湖水源热泵方案,并分析各个方案的综合效益,选择适用于该新建办公楼的湖水源热泵系统方案。其中湖水多水体串联的方案可以很大程度上起到湖水源热泵空调系统扩容的作用。所以,今后在进行类似地表水源热泵空调系统方案设计时,现场的实测数据与水体串联方案可作为参考与借鉴。

The depth,temperature and quality for water of a lake is comprehensively investigated in north-central Hunan,and the feasibility of the lake water source heat pump is analyzed. In order to accurately calculate the carrying capacity for heat of the lake in the summer,the natural water temperature is predicted with the lake water temperature prediction model. Then three kinds of lake water source heat pump schemes are proposed,and the comprehensive benefits of which are analyzed to choose the best scheme for the new office building. This study demonstrates that the scheme of multi-water system will enhance the efficiency of the lake water source heat pump. Therefore,the measured data and the scheme of multi-water system in this paper can be referenced in the design of similar surface water source heat pump system.
