针对太阳能热泵系统集热效率和 COP 不高的问题，提出了3种太阳能双水箱系统设计方案，基于其中一种方案设计了自控系统并搭建了实验台，研究了不同运行工况对系统集热效率和 COP 的影响．实验结果和理论分析表明：集热效率比 COP 更能反映系统运行效果．在合适的控制参数下，双水箱联合运行的集热效率与相变水箱单独运行情况基本相同，前者高效集热时间为上午8点到下午4点，后者集热时间集中在中午．与普通水箱单独运行相比，两者的集热效率由0.64增加到0.94以上，COP由2.32增大到5.00以上．

To solve the problem that the collection efficiency and COP of the solar energy system assisted heat pump is not high, three kinds of designs for solar energy system assisted dual water tank were proposed. Based on one design,automatic control system was designed and test bench was built. The effects of operation strategies on the collection efficiency and COP were investigated. The experimental results and theoretical analysis show that collection efficiency is better for reflecting the system efficiency than COP. With appropriate control parameters,the collection efficiency of joint work of dual water tank is basically the same as that of separate work of a water tank with phase change material. The former stores heat efficiently from 8:00 am to 16:00, while the latter does so almost at noon. Compared with the separate work of an ordinary water tank,the collection efficiency of the joint work of dual water tank is increased from 0.64 to above 0.94, and COP is increased from 2.32 to above 5.00.
