摘要
在地热供热系统中,地热利用率制约着系统各项指标,如果单从经济性对地热供热系统进行分析,相对单一且具有局限性。该文基于突变级数法,建立地热供热系统评价模型,并利用该模型对天津市某地热供热梯级利用系统在不同地热利用率下的经济效益、环境效益、资源效益及其综合效益进行分析,得出最佳回灌温度,可为地热供热系统评价提供一种优化理论模型,具有实际意义。
In geothermal heating system, the utilization of geothermal heat restricts indexes of the system. If only analyzing from the economic benefits of this system is relativly single and has limitation. This paper which is based on catastrophe progression method, builds an evaluation model on the utilization of geothermal energy, and makes analysis on geothermal heating cascade utilization system （somewhere in Tianjin） in different geothermal utilizations of aspects in economic, environmental and energy-saving benefits and their comprehensive benefits. What＇ s more, it results in the optimal recharge temperature which provides a theory of optimization algorithm for geothermal heating cascade utilization system, and has certain practical significance.
