摘　　要：对太阳热水器贮热水箱的结构进行改进，并从平均日效率和平均热损系数两个方面对太阳热水器进行实验研究。结果表明：与常规系统相比，采用新型贮热水箱的太阳热水系统平均热损系数下降1．35～3．42w／（m2．K）。平均日效率提高2．37％～4．02％。In order to further improve the thermal performance of solar hot water system, the structure of heat storage water tank was improved. The thermal performance of solar hot water system with novel water tank was studied, and it was compared with conventional water tank. The results show that the average thermal loss coefficient of solar hot water system with novel heat storage water tank is reduced by 1.35-3.42 W/（m2· K） , and the average daily efficiency is increased by 2.37%-4.02%.
