摘　　要：提出一种半覆盖外置式光伏热催化型Trombe墙,数值研究光伏电池覆盖率和太阳辐射强度对其性能的影响,并与半覆盖中置式光伏热催化型Trombe墙性能进行比较。结果表明:随着覆盖率的增加和太阳辐射强度的降低,热效率降低;覆盖率对电效率影响较大;不同太阳辐射强度下,在覆盖率为0.64时,净化空气量达到最佳。对比半覆盖中置式光伏热催化型Trombe墙,尽管热效率有一定程度的降低,但电效率的相对提高可达20.64%,空气净化效率相对提高可达11.57%。A novel partially-covered and built-out photovoltaic-thermocatalytic-Trombe wall(PBOPVTC-TW)was proposed.The effects of photovoltaic cell coverage ratio and solar radiation intensity on performance were numerically analyzed,and the performance comparison between PBOPV-TCTW and partially built-middle photovoltaic-thermocatalytic-Trombe wall(PBMPV-TC-TW)was carried out under the same conditions.The results show that the thermal efficiency keeps declining as the photovoltaic cell coverage ratio increases and solar radiation intensity decreases,and the photovoltaic cell coverage ratio has a greater impact on electrical efficiency.When the coverage ratio is 0.64,the clean air delivery rate(CADR)is optimal under different solar radiation intensities.Compared with the PBMPV-TC-TW,although the thermal efficiency of PBOPV-TC-TW is reduced to some extents,the electrical efficiency is relatively increased by up to 20.64%,and the air purification efficiency is relatively increased by up to 11.57%.
