摘要
将全玻璃真空管太阳能集热器与土壤源热泵相结合,在某四合院搭建了一种太阳能–土壤源热泵示范系统,并为该系统冬季供暖制定了运行模式及运行策略。在供暖期内对系统全天运行特性的影响因素进行比较分析,结果表明系统全天平均性能系数COPall随太阳能的贡献比例fsc升高而增大;随地热能对热负荷的贡献比例fsc升高而减小;随电能对热负荷的贡献比例fe升高而减小。太阳能对热负荷的贡献比例fsc集中在0.6左右。
This thesis combined all-glass vacuum tube solar collector and the ground source heat pump establishes a energy-ground dual source heat pump system in a courtyard, and developed the operating mode and operating strategy for heating in winter. Compare and analyses the factors that affected the running characteristics of the system throughout the day. The results showed： the average performance coefficient of system throughout the day COPall increases with the solar energy＇s contribution ratio fsc, decreases with the rise of the geothermal energy＇s contribution to the heat load ratio fg, and decreases with the rise of the electricity energy＇s contribution to the heat load ratio fe. The solar energy＇s contribution ratio to heat load fsc concentrated around 0.6.
