中文摘要:
      太阳能屋顶的安装预计能在一定程度上缓解城市化所带来的能源危机及城市热环境的破坏。利用耦合了城市单层冠层方案(UCM)的WRF模式,以南京2010年7月27日至8月5日夏季晴天小风天气为背景,模拟了不同发电效率的太阳能屋顶的安装对城市高温的缓解效应。结果表明:(1)太阳能屋顶可以通过削弱到达城市表面的太阳辐射使城市2 m气温降低,随着发电效率的增大,降温效果越明显,且白天降温效果明显优于夜间;白天2 m气温最大降低0.4—1.3 ℃,夜间降低0.2—0.5 ℃;(2)太阳能屋顶可使边界层内气温降低,白天在边界层400 m以下降温显著,夜间在边界层高度200 m以下降温显著;白天边界层内最大降温出现在中午前后,降温0.1—0.8 ℃,夜间边界层内最大降温0.5 ℃;(3)发电效率为40%时,模拟期间的发电量为18.1×109 Kwh。
英文摘要:
      The installation of rooftop solar photovoltaic is expected to remit the energy crisis and urban thermal damage caused by urbanization to some extent. The non-hydrostatic version of the Weather Research and Forecasting (WRF) model coupled with single layer urban canopy model (UCM) was utilized to simulate the mitigate effect with different power efficiency of rooftop solar photovoltaic in a sunny and breeze weather from 27 July to 5 August,2010. The results indicated that:(1) The installation of rooftop solar photovoltaic via the generation of energy that offsets the need to import amount of energy into the city. This leads to cooling since the energy used by the solar panels, which would have otherwise heated urban surfaces and then radiated energy into the atmosphere.Cooling effect was more significant with the solar panel efficiency increase, and the day cooling effect was significantly better than the night. During the day, the maximum 2 m temperature decreased by 0.4—1.3 ℃ and 0.2—0.5 ℃ at night. (2) The installation of rooftop solar photovoltaic reduced planetary boundary layer (PBL) temperature, and the cooling effect was significant below the boundary layer 400 m and 200 m in the day and night, respectively. The maximum decrease in PBL temperature during the day occurs around noon ,and the temperature decreased within the PBL could reach up to 0.1—0.8 ℃ and 0.1—0.5 ℃ in the day and night, respectively. (3) Power generation capacity was 18.1×109 Kwh by the 40% power generation efficiency within 9 days.
