福州市地下水源热泵抽水回灌试验研究

Experimental study on groundwater source heat pump pumping recharge in Fuzhou

地下水源热泵是一种新型的节能环保空调技术,在城市浅层地温能开发利用中发挥着巨大作用。福州市地下水资源丰富,地下水源热泵系统使用前景广泛。本文通过对福州市水文地质条件的分析,初步确定了福州盆地平原区为地下水源热泵应用的适宜区及较适宜区,通过在这些地区开展的现场抽水、回灌试验,确定福州市不同岩性含水层的回灌能力、抽灌井数量比例及井间距的设计参数,为福州市浅层地温能的开发、水源热泵技术的合理应用提供科学依据。

Underground water source heat pump is a new energy-saving and environment-friendly air conditioning technology,which plays an important role in the development and utilization of shallow geothermal energy in cities.Fuzhou is rich in groundwater resources and has a wide application prospect of underground water source heat pump system.Based on the analysis of hydrogeological conditions in Fuzhou,the plain area of Fuzhou basin is preliminarily determined as the suitable area and the more suitable area for the application of underground water source heat pump.through the on-site pumping and recharging tests carried out in these areas,the recharging capacity,the number ratio of pumping and recharging wells and the design parameters of well spacing of different lithologic aquifers in Fuzhou are determined,providing scientific basis for the development of shallow geothermal energy and the rational application of water source heat pump technology in Fuzhou.
