摘　　要：提出了一种新型光伏-直膨太阳能热泵(PV-DXSAHP)的系统原理,建立了PV-DXSAHP系统试验台。对PV- DXSAHP系统在水温从15℃升高到55℃工况下的动态性能进行了测试和分析,结果显示,在水温升高到55℃时,PV-DXSAHP系统COP为4.1,测试过程的平均光电效率为13.2%。研究表明PV-DXSAHP系统具有优越的热泵性能和光电转换效率。The principle of a novel Photovoltaic-Direct Expansion Solar Assisted Heat Pump （PV-DXSAHP） was proposed in this paper. A prototype of PV-DXSAHP was set up and test was performed under the mode of condensing water rising from 15℃ to 55℃ in Hefei. It was fotmd that the COP is 4.1, and the efficiency of the PV device was 13.2% in the test. Results show that the thermal performance and the efficiency of PV device in the PV-DXSAHP system is clearly higher than normal heat pump and normal PV module.
