摘要
由于严寒地区土壤源热泵取热和放热不均,土壤温度逐年下降,需要针对寒区运行情况制定补热方案。本文以严寒地区某典型建筑为例,基于TRNSYS对地源热泵系统运行特性进行仿真研究,分析地源热泵系统关键设计参数对系统运行特性的影响,其结论为严寒地区地源热泵系统设计参数选取及辅助热源补热策略提供参考。
Because of the heat is unbalanced when the ground source heat pump （GSHP） system running in severe cold region, the soil temperature declined year by year. We need to make heat supplement program for this running state. Based on TRNSYS, the operation characteristic of ground source heat pump was analyzed theoretically by a typical building in severe cold region. Simultaneously, the analysis of the key design parameters, which influenced the operation characteristic of ground source heat pump, was carried out. The conclusion could provide a reference for design parameters selection and heating strategy of auxiliary heating source.
