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。 Water source heat pump usually adopts the means of pressure recharging to infuse the water into the underground aquifer, and a large amount of gas will enter the recharging layer along with the recharge water during the pressurization. When the pressure is continuously reduced, the gas in the recharged water is released continuously and bubbles in the aquifer to form a gas-phase blockage. In this paper, the effect of gas-phase plugging on recharge is studied through pressure-recharging experiment and the quantitative analysis is made. Finally, a method of alleviating gas-phase plugging is proposed.
