沈阳某地地下水水源热泵回灌衰减问题分析

Groundwater Source Heat Pump Recharge Attenuation Analysis in Somewhere of Shenyang

人工回灌是地下水水源热泵中必不可少的一部分,而衰减问题是人工回灌中的关键,衰减因素可分为自然因素和人为因素等。影响地下水水源热泵人工回灌的因素有回灌地区水文地质条件、回灌水水质以及回灌方案选取等。研究中人工回灌采用重力回灌和压力回灌两种形式,可以反映出在不同阶段各种衰减因素对回灌的影响。对回灌因素的不同时间尺度进行分析,对各阶段的影响因素进行分析后,有针对性地提出对各种影响因素的解决办法,提高回灌效率,从而使地下水水源热泵运行更加顺畅。

Artificial recharge is an essential part of the groundwater source heat pump ,while the attenuation problem plays an impor‐tant role in it .The attenuation factors can be divided to natural and artificial factors .Influential factors of artificial recharge in groundwater source heat pump include hydro-geological conditions of the recharging area ,quality of the recharge water and the selec‐tion of recharge method .Gravity recharge and pressure recharge are used in this study ,which can reflect the influence that a variety of decay factors affecting the recharge in different stages .Through analyzing factors of different time scales and factors of different stages ,putting forward the solving method to all factors and raising recharge efficiency ,the groundwater source heat pump can run much more effectively .
