为了将地下水源热泵系统应用于高原河谷地区,分析某高原河谷地区的地勘资料,认为利用地下水源热泵系统区域供热是适宜的。考虑采暖负荷逐时变化和机组COP随负荷率的变化,对高原河谷地区地下水源热泵供暖系统的机组配置和运行进行优化,使得系统供热季能效比达到3.44。均不考虑末端设备时,与传统燃气锅炉供暖系统相比,该高原河谷地区地下水源热泵系统初投资增量为36.45%,年运行费用节约18.31%,投资增量回收期为7.79 a。该成果对高原河谷地区应用地下水源热泵系统采暖具有一定的参考价值和指导意义。
In order to apply the groundwater source heat pump system to the plateau valleys and analyze the geological survey data of a plateau valley, it is considered that it is appropriate to use district ground source heat pump system for district heating. Considering the time-varying change of heating load and the change of unit COP with load, the unit configuration and operation of ground-source heat pump heating system in plateau valleys were optimized so that the energy efficiency ratio reached 3.44 during the heating season. Compared with the conventional gas boiler heating system, the initial investment increment of groundwater heat pump system in the plateau valley was 36.45%, the annual operating cost was saved by 18.31%, and the incremental payback period of investment was 7.79 years. The results of the application of groundwater source heat pump system in the plateau Valley has some reference value and guiding significance.
