摘　　要：对直接式和间接式低温地热供热系统的设计与质调节问题进行了分析和讨论，给出了不同室外温度条件下的混水比例的计算方法和公式，为低温地热供热系统的优化设计和控制提供了理论依据。The supply temperature is a important parameter for the control and optimum design of geothermal district heating systems However,the wellhead temperature is almost fixed for a specific geothermal well in most of cases In this paper,both method of design and supply temperature adjustment for direct and indirect geothermal district heating systems are theoretically analyzed and discussed Also,the formula for calculating the mixing ratio with the change of outdoor temperature in direct geothermal heating systems is given

关 键 词：地热供热 质调节 间接式 直接式 供热系统
