摘要:指出地源热泵运行时,其地埋管换热器全年吸/排热平衡的重要性,混合式地源热泵在工程应用时,主要作用之一是维持地埋管换热器的全年“热平衡”。通过对合肥地区几类常见的典型建筑进行全年能耗模拟,得出不同建筑冬、夏季地埋管换热器吸/排热的比例,结合某具体混合式地源热泵实验,分析出基于全年地埋管换热器“热平衡”的不同类型建筑应用混合式地源热泵的控制方法和控制参数。

Abstract: Pointed out the importance of the balanced of the GSHP’s ground heat exchanger heat absorption and heat-removal in a whole year, HGSHP in project application, one of leading roles is the maintenance of ground heat exchanger annual “thermal equilibrium”. Carries on the annual energy consumption simulation to the HeFei area several kind mon model constructions, obtains the different construction winter, the proportion of ground heat exchanger heat absorption and heat-removal in a whole year, with a concrete HGSHP experiment, analyzes based on the annual ground heat exchanger “the thermal equilibrium” different type construction application HGSHP’s control method and controlled variable.
Key words: HGSHP; thermal equilibrium; control method; energy consumption simulation
地源热泵被“认为”是一种利用地能的空调形式,但在工程应用中有很多失败的案例,很多是因为地埋管周围的岩土温度逐年升高(降低),导致地埋管换热系统的瘫痪,主要原因是由于地源热泵在地下水流动缓慢地区使用时实质上是一种转移冬、夏季空调负荷的“蓄能”空调。近年来,在夏季空调冷负荷大于冬季空调热负荷的地区大量的采用了地源热泵地埋
