| 分析了小型湖泊应用于地表水源热泵时的两种热承载能力计算方法——水面温度法和均匀混合法，并采用其计算了杭州小型湖泊应用于地表水源热泵时的热承载能力。计算结果表明：水面温度法较客观地反映了实际的排水混合及水温恢复过程，可信度更高。用水面温度法对7个代表性城市小型湖泊热承载能力进行分析的结果表明：夏季热承载能力在23.4~29.5W/m2之间，冬季热承载能力在31.6~45.7W/m2之间；设计这类系统的关键在于满足夏季热承载能力的约束。 |
| 英文摘要: |
| Two thermal load capacity calculation methods including the water surface temperature method and the uniform mixing method for small lakes utilized as heat source-sink of surface water heat pump sys?tems were introduced. The calculation results of the Hangzhou City indicate that the water surface tempera?ture method is more convincing because it objectively reflects the process of discharge-mixing and water temperature recovering. Thermal load capacity calculations of small lakes in seven representative cities were performed. The results show that the thermal load capacity in summer varies from 23.4W/m2 to 29.5W/m2，and that in winter varies from 31.6W/m2 to 45.7W/m2. The key issue for the design of such surface water heat pump systems is to satisfy the constraint of thermal load capacity in summer. |
