基于TRNSYS的多热源复合式供热系统经济性研究

Research on the economy of multithermal composite heating system based on TRNSYS

以TRNSYS模拟软件为平台,构建了一套由太阳能、土壤源热泵、热网三种热源组成的多热源复合式供热系统;以哈尔滨市某案例为研究对象,基于不同峰谷电价比时不同热源占比的复合式供热系统的运行特性进行研究,分析不同热源占比的复合式供热系统的经济性。研究结果表明:该多热源复合式供热系统,在工况三的运行模式下,基于三种峰谷电价比,系统均能取得较优的经济性。

Based on TRNSYS simulation software, a multi-heat source compound heating system consisting of solar energy, soil source heat pump and heat network was constructed. Taking a case of Harbin city as the research object, studies the operation characteristics of the multi-heat source compound heating system with different heat source proportions in different peak-valley electricity price ratios, analyzes the multi-heat source compound heating system with different heat source proportions. The results show that for this multi-heat source compound heating system, under the operating mode of working condition three, based on the peak-valley price ratio, the system can achieve better economy.
