| 摘 要： | 本文采用蓄热水箱的多节点模型，对典型太阳能热水系统进行了全年逐时模拟计算。计算数据表明，相比于完全混合的蓄热水箱，水箱温度分层可较大幅度提高太阳能集热器平均效率和太阳能保证率。同时还分析了不同气象条件、集热器类型和用水模式等条件下，蓄热水箱温度分层对太阳能热水系统性能提高程度的影响。

| Abstract: | In this paper,the multimode approach was used to model temperature stratification in water tank,and hourly simulation of a typical Solar Domestic Hot Water system(SDWH) during a whole year was carried out.The results indicated that collector efficiency and solar fraction of SDWH system could be significantly increased with the temperature stratification in storage tank.Meanwhile,the effect of some factors,such as meteorological conditions,types of collector and the load profiles of hot water,on the performance improvement of SDWH system using stratified storage tank was discussed. |
