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 loads of typical office buildings, the influence of the design parameters of ground tube heat exchangers in the ground source heat pump system on the energy efficiency of the system was studied. The results show that increasing the spacing of buried tube heat exchangers is beneficial to improve the reliability of the system. Increasing the buried depth of the buried tube heat exchangers under the same heat exchange capacity is conducive to stabilizing the soil temperature and reducing the heat to the soil interference.
