地铁源热泵系统适应性研究

Study on adaptability of subway source heat pump systems

选取哈尔滨、北京、青岛、西安、上海、武汉、重庆、南宁、广州9个典型城市,以办公建筑为例,搭建了不同气候区的DeST建筑模型,依据不同城市的气候、地质等参数建立了地铁源热泵系统TRNSYS模型,结合适应性评价指标分析了不同城市对应热泵系统的性能、经济性和环境效益,提出了适应性评价体系。根据综合评价体系得出地铁源热泵系统在不同城市的适用情况如下:哈尔滨、青岛、西安中等适用,北京一般适用,上海、武汉优化后中等适用,广州优化后一般适用,重庆、南宁不适用。

In this paper,nine typical cities including Harbin,Beijing,Qingdao,Xi’an,Shanghai,Wuhan,Chongqing,Nanning and Guangzhou are selected to build DeST building models in different climate zones by taking office buildings as examples.The TRNSYS model of subway source heat pump systems is established according to the climate and geological parameters of different cities.The performance,economic and environmental benefits of the corresponding heat pump systems in different cities are analysed with the adaptability evaluation indexes,and the adaptability evaluation system is proposed.According to the comprehensive evaluation system,the applicability of subway source heat pump systems to different cities is as follows:Harbin,Qingdao and Xi’an are moderately applicable,Beijing is generally applicable,Shanghai and Wuhan are moderately applicable after optimization,Guangzhou is generally applicable after optimization,Chongqing and Nanning are not applicable.
