摘　　要：以某地热水供热工程为例,分别采用了国内、国外两种设计方法。比较了系统流程设计、室外管网布置、末端散热设备、系统造价及运行费用。采用国内设计方法系统造价低但运行费用高,从长远考虑,建议采用国外的设计方法。Taking a geothermal water heating engineering for example, the domestic and foreign two design methods are used respectively. The system process design, arrangement of outdoor pipe network, end heat radiation device, system cost and operation cost are compared. The domestic design has lower system cost, but higher operation cost. From the long-term consideration, it is suggested that the foreign design method is used.
