摘　　要：介绍一种用于太阳能空调系统的多级水箱蓄热系统,在对其进行了理论分析的基础上,借助搭建的多级水箱蓄热试验装置,对不同级数系统的性能进行了试验研究。结果表明:随着多级水箱蓄热系统级数的增多,第一级蓄热水箱完成蓄热耗时变短,蓄热量品位逐步提高;在蓄热过程中系统级数越多,理想供热进口水温工作时间越长,但放热过程中情况与之相反。据此提出了系统的优化改进方案,优化改进后的系统对理想供热进口水温工作时间的延长效果明显。The system of multistage tanks applied to the solar air conditioning was presented. Above the theoretical analyzing,the system of multistage tanks test-bed has been built to study the performance of the multistage tanks system with different series.The results showed that： the heat storage consuming time of the first-stage tank decreased and the heat storage grade improved with increasing the system series,and the time of ideal heating inlet water temperature increased with increasing the system series,in the heat release period,the conclusion is opposite. According to the above conclusion,the optimization strategy for the system of multistage tanks was proposed,the system after optimization has obvious effect on prolonging the time of ideal heating inlet water temperature.
