摘　　要：阐述了地表水源热泵水体热污染问题的由来、原因与影响因素,分别探讨了开式地表水源热泵系统和闭式地表水源热泵系统水体热污染的特点,提出了解决该问题的若干技术思路,结合实际项目说明了热污染问题对地表水源热泵的影响并不致命的,既要尊重地表水的"承载力"又不能机械地提倡教条式的"热污染"理论,设计合理的地表水源热泵系统完全可以避免水体热污染问题。Describes the origin,causes and effect factors of water heat pollution of surface water source heat pump,explore the characteristics of water heat pollution of open-loop SWHP system and closed-loop SWHP system respectively,proposes several technical ideas for solving the problem.Meanwhile,combined with the two actual projects,illustrates the impact of water heat pollution problem on SWHP is not fatal,and it is necessary to respect the ＂heat capacity＂ of surface water,but should not advocate the dogmatic＂water heat pollution＂ theory Mechanically,proves that SWHP system with rational design can entirely avoid water heat pollution.

关 键 词：水体热污染 地表水源热泵 热承载能力 温度控制
