摘　　要：地下水式水源热泵系统是一种节能的小型商业建筑和民用建筑的制冷取暖方案。为研究其对地下水环境是否污染,分析了北京某开发区水源热泵系统运行后对地下水环境监测资料,建立了该系统运行后地下水微生物生长的数学模型,并与美国地质调查局开发的HST 3D程序相结合,在模型率定和验证的基础上,对地下水式水源热泵系统影响地下水细菌环境的过程进行了数值模拟。计算表明:在地下水环境中温度梯度变化较大的地方,细菌总数和大肠杆菌总数变化也较大,并容易形成一个高浓度的细菌和大肠杆菌微生物圈,其余地方细菌总数和大肠杆菌总数变化较小。As a clean energy resource, groundwater source heat pumps have become one of the most popular air-conditioning systems installed in small-commercial and governmental buildings in China. A mathematical model of the microbe growth in such systems was constructed based on long-term field data on the groundwater quality of a site in Beijing and incorporated into HST3D, a program developed by the U.S. Geological Survey. Simulations of the environment impact to groundwater source heat pumps show that the microbe population does not grow much in the system except at the boundary of the cold and warm water mixing area where a ring of high concentration microbes comes into being.
