摘要
在水源热泵系统的应用中,取水温差设计的合理性直接影响输配系统能耗,一般地理位置决定了取水扬程的大小,但对取水量可在满足系统冷热量的前提下,通过优化设计取水温差,同时与机组性能相匹配,最终实现系统高效运行。通过研究水源热泵机组在不同进水温度与不同流量大小下的机组EER值,结合不同流量大小下的输送水泵轴功率变化情况,以制冷系统能效比EERr作为最佳温差的判定依据。
In the application of water-source heat pump system, whether the water-intake temperature design is suitable or not will affect energy consumption of distribution system directly. Generally, water-intake lift is based on the geographical position. However, the high efficient operation of water-source heat pump system can be achieved through optimizing the design of water-intake temperature and fitting the temperature with the pump’s function under the premise that the quantity of water-intake can guarantee to provide enough heat and cool energy for system. In this article the energy efficiency ratio （EER） of water-source heat pump under the condition of different water-intake temperatures and different flow rates is researched and the most suitable water-intake temperature can be finalized on the base of the EER of refrigerating system （EERr） and the changes of shaft power of water distribution pump under different flow rates.
