通过地源热泵热物性测试和逐时负荷计算结果,进行了地埋管换热器设计、冷却塔选型以及机房设计。热物性测试结果表明,平均地温为21.97℃,平均导热系数为2.76 W/m·K;在管内流速0.43 m/s,进/出水温35/30℃的散热工况下,平均每延米换热量为57.51 W/m;相同流速、进/出水温为7/12℃的取热工况下,平均每延米换热量为68.27 W/m。
The ground heat exchanger design, cooling tower selection and engine room design were carried out through the geophysical heat source test and hourly load calculation of the ground source heat pump. The results of thermophysical properties show that the average ground temperature is 21.97 ℃ and the average thermal conductivity is 2.76 W / m · K. Under the condition of cooling rate of 0.43 m / s and inlet / outlet water temperature 35/30 ℃, The heat quantity is 57.51 W / m; under the condition of heat release with same flow rate and inlet / outlet water temperature of 7/12 ℃, the average heat exchange per meter is 68.27 W / m.
