摘要
水源热泵通常采取压力回灌的手段将水体灌回地下含水层,在加压过程中大量气体随回灌水源进入回灌层。当压力不断减小时,回灌水源中的气体不断释放,并以气泡的形式存在于含水层中形成气相堵塞。本文主要通过压力回灌试验研究气相堵塞作用对回灌的影响程度并进行量化分析,最后提出缓解气相堵塞的方法。
The groundwater is usually injected into aquifers through pressure recharge in groundwater source heat pump system. Dur- ing the pressure-increasing process, a mass of gases enter into recharge layer with the recharge water. While with the decrease of pressure, gases are released into aquifers and stored in the aquifers in the form of bubbles, which can block the water channels. In this paper, the impact degree of gas clogging on recharge is quantized through pressure recharge experiment and the solving methods are proposed.
