摘　　要：针对以太阳能集热系统恢复埋管周围岩土温度的土壤源热泵建筑供暖的复合系统,研究该系统太阳能集热器面积的合理选择方法。在西安市气候条件下,针对10000 m^2的住宅建筑面积,应用TRNSYS软件建立该复合系统的动态运行换热模型。根据太阳能集热系统是否在冬季联合供暖运行分2种工况进行多种条件的仿真计算,得到对应不同岩土导热系数值的相对最佳集热器面积,从而得到这2种工况的单位建筑面积相对最佳集热器面积与岩土导热系数的关系。For a solar-assisted ground source heat pump composite system with solar energy collector to restore rocksoils temperature around the buried pipe that used to supply heat in buildings,the reasonable selection method for the area of solar collectors in this system is studied.Under the climatic conditions of Xi’an,the dynamic heat transfer model of the composite systems is established by using TRNSYS software for the residential building area of 10000 m^2.According to whether the solar thermal system is running in the winter for combined heating,the simulation calculation is carried out in two working conditions,and the optimal collector area corresponding to the different thermal conductivity of rock-soils is obtained.Therefore,the relationship between the optimal collector area per unit building area and the thermal conductivity of rock-soils is obtained.
