在水环热泵空调系统中有串联在水环路上的蓄热水箱来改善系统的运行特性。
A heat storage tank was connected in series with the water loop to improve the system running characteristics.
有蓄热水箱时的联合供暖运行模式二(集热器与埋管串联运行，载热流体先经过埋管后进入集热器)的效果最佳。
The operation mode with water tank in which the hot water flows through the solar collector first and then the buried coil is preferable.
结果表明，与土壤源热泵相比，联合供暖运行模式具有明显的节能效果，有、无蓄热水箱时的节能率分别为14。
The result shows that comparing with ground source heat pump, the energy saving rate with and without heat storage water tank is 14.
