| 摘 要： | 长江水资源丰富，可作为水源热泵系统的低位冷热源。针对长江水源特点进行了开式系统与闭式系统的对比实验，获得了两者的机组性能系数、系统整体性能系数、闭式系统中换热器内水温变化规律以及有效换热管段等参数。分析了对比实验数据，得出本实验中开式、闭式系统热泵机组性能系数分别为3．08和3．77，整体性能系数分别为2．38和2．80。最后对开式和闭式长江水源热泵的应用作了对比分析，指出了应用长江水作低位冷热源必须注意的问题。

| Abstract: | Yangtze River is abundant of water and can provide enough water as cooling and heating source for water source heat pumps(WSHP).A pair of contrast experiments with open-loop system and close-loop system of WSHP were finished in order to get the heat pump's COP,the system's COP and the distribution of water temperature in the heat exchanger etc.This paper compared the characteristic and the COP of these two kinds of system.The heat pump's COP of the open-loop system and close-loop System are 3.08 and 3.77 re... |
