摘　　要：选取太阳能PV/T与热泵一体化系统中的蓄热水箱作为研究对象,通过试验与数值模拟的方法,分别研究不同流速工况(0.10,0.15,0.20 m/s)以及不同蓄热水箱结构对其温度分层性能的影响。结果表明,在0.10 m/s流速下,进、出水口温差约为2℃,且进水流速越大,进水口与出水口之间的温差越小;结构1水箱的取出效率为11.44%,结构2水箱的取出效率12.43%,所以进、出水口位置分布越远,水箱温度分层效果越好。In this study,the thermal storage tank in the PV/T integrated heat pump system was selected as the research object.Through experimental and numerical simulation,the effects of different flow velocity conditions(0.10,0.15,0.20 m/s)and different tank structures on its temperature stratification were studied.The results show that under the flow rate of 0.10 m/s,the temperature difference between the inlet and outlet was 2℃.And it is concluded that the greater the inflow water flow rate,the smaller the temperature difference between the water inlet and the water outlet.The heat release efficiency of structure 1 was 11.44%,and that of structure 2 was 12.43%.Therefore,the farther the inlet and outlet locations are kept apart,the better the stratification effect of the water tank temperature.
