摘　　要：地表水源热泵的取水方式多种多样,每种取水方式都有相应的适用条件。本文分析了几种取水方式的原理及适用范围,给出了地表水源热泵系统取水方式的遴选原则。着重介绍了负压引流取水方式,从不同的进水方式和出水方式入手,探讨了在地表水源热泵系统中,负压引流罐的设计原理和方法。同时,水泵及负压引流罐的安装高度也应根据实际使用情况进行校核,避免发生水汽化现象。Surface water source heat pumps have a variety of water intake methods, and each water intake method has corresponding applicable conditions. The principles and application scope of several water intake methods were analyzed, and how to select the method was discussed. The negative pressure drainage and water intake methods were highlighted. Starting with the inlet and outlet methods, the design principle and method of negative pressure drainage tank in surface water heat pump system was explored. Meanwhile, installation heights of pump and negative pressure drainage tank should be checked according to practical utilization condition in order to avoid water vaporization.
