摘要
根据严寒地区冷热负荷不平衡的特点,提出一种新的蓄热型太阳能-土壤复合热源热泵系统,建立了包括太阳能集热器、地埋管换热器及土壤、热泵机组在内的系统数学模型,以严寒地区为例,对太阳能-地源复合热泵运行过程中不同蓄热模式土壤温度变化进行了数值模拟,结果表明:该系统较单一热泵有明显优势,解决了严寒地区冷热负荷不平衡问题,提高了系统效率和运行稳定性。
A new type of solar assisted ground source heat pump （SAGSHP） heating system with heat storage tank was proposed according to the characteristics of unbalanced cooling and heating load in cold regions,and the mathematic model for this system consisting of solar collector,ground heat exchanger,soil and heat pump was built to perform numerical simulation on variation of soil temperature under different heat storage modes in the operation process of solar assisted ground source heat pump in cold area,for example. The results show that this system has distinct advantages over single-source heat pump,it solves the problem of unbalanced cooling and heating load in cold regions,and improves coefficient of performance and stability of the heat pump system.
