摘要
我国北方大部分地热资源是以地热水形式存在的低焓能源。在应用于集中供热时与锅炉供热有着本质的区别。前者可认为是恒温、变流量热源,而后者是变热流、可调温的热源。从机理上认识这两种热源的特点对集中供热的设计、调节和控制至关重要。着重对地热间接式供热系统进行了全面的热力分析。
The indirect geothermal district heating system (IGDHS), so called for using heat exchangers to prevent corrosive geothermal water from flowing through the system, is different from the conventional heating system with a fossil fuel boiler as its heat source and can not be regulated by altering temperature of the water. Gives a thermal analysis of the former and discusses the selection of heat exchansers and optimum operating conditions.
