摘要
水系统变流量运行可以减少输配能耗,地源热泵地源侧变流量技术还处于研究阶段,与冷却水系统有着相似之处。冷却水变流量运行的节能效果与冷却水泵的能耗比例相关,比例越大节能效果越显著,而地埋管地源热泵的地源侧管路复杂多变且管程较长,地源水在流动过程中所产生总阻力比冷却水的总阻力大,循环水泵的功率也相对较大,研究地源水的变流量技术更有意义。
The variable flow of water system operation can reduce the energy consumption of distribution. The technology of variable heat pump ground source water flow rate system is still on research stage which is similar to the cooling water system. The energy saving effect operated by variable cooling water flow rate is related to proportion of energy consumption of cooling water pump, so energy saving effect is more significantly with larger proportion. Ground source side pipeline of ground source heat pump of underground pipe is complicated and tube side is very long, which brings larger total resistance and bigger energy consumption than cooling water system, so the research on technology of variable ground source water flow rate is more significant.
