地下水源热泵系统在地下水顺流模式下,不同的地下水横流速度对热泵性能参数的影响不同:顺流水流速越小,系统发生热贯通时间越晚;流速越大,发生热贯通时间越早。地下水横流流速度越大,热泵机组的COP越大,系统能效比越大。随着地下水横流流速增大,垂直顺着水流方向上温度场变化区域逐渐减小,为了减少井群占地区域,顺流模式下同类井群间距可以适当减少。
Groundwater source heat pump system in the groundwater downstream model, different groundwater cross-flow velocity of the heat pump performance parameters are different: the lower the flow rate of the downstream, the system heat through the passage of time; the greater the flow rate, the sooner the heat through time. The greater the groundwater cross-flow velocity, the larger the COP of the heat pump unit, the greater the system energy efficiency ratio. As the flow velocity of groundwater increases, the change of temperature field vertically along the flow direction decreases. In order to reduce the area occupied by the well group, the spacing between similar wells in downstream mode can be reduced appropriately.
