摘　　要：以典型办公建筑全年动态负荷为依据,对严寒地区土壤源热泵系统地埋管换热器设计参数对系统能效的影响进行研究。研究结果表明,增大地埋管换热器间距有利于提高系统运行可靠性,在换热能力不变的前提下增大地埋管换热器埋深,有利于土壤温度稳定,降低对土壤的热干扰。Based on the annual dynamic load of typical office building,the optimizationg analysis on system energy efficiency with design parameters for ground heat exchanger was carried out by a case study in severe cold region. The present study indicates that the reliability of ground source pump system could be improved by better spacing of ground heat exchangers. The more depth of ground heat exchanger,which is kept the same heat transfer capacity,is beneficial to improve the stability of soil temperature and reduce the thermal interference of soil.
