Study on adaptability of subway source heat pump systems

 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.
