中文摘要:
      [目的]太阳能光伏屋顶的安装在一定程度上缓解城市化带来的能源危机和城市热环境的破坏。[资料和方法]将太阳能板的传热模型引入WRF的多层城市冠层方案中,选取了一次典型的高温热浪过程,在线模拟太阳能屋顶两种安装形式(贴覆式和支架式)对城市热环境及能量平衡的影响。[结果与结论]结果表明:(1)贴覆式太阳能屋顶可使白天2m气温最多降低0.29°C,降温效果优于支架式安装,但夜间温度下降较小。支架式屋顶白天最大降温0.23°C,夜间降温效果明显,与普通屋顶相比,温度最多降低了0.60°C。(2)太阳能屋顶白天确实可以起到降温效果,但同时也会削弱湍流影响,抑制白天边界层的发展,降低边界层的高度。在湍流发展旺盛的情况下,太阳能屋顶的弱化效应更加明显。(3)太阳能屋顶除了对城市气象的影响外,最重要的是它对能源的贡献。从结果来看,太阳能电池板产生的电能可以满足商业区54.5%的空调消耗。
英文摘要:
      The installation of solar roofs is expected to alleviate the energy crisis caused by urbanization and the destruction of urban thermal environment to a certain extent. The heat transfer model of solar panels is introduced into the WRF multi-layer urban canopy scheme, and the effects of solar roofs in two installation forms (attached roof and scaffolding roof) on urban thermal environment and energy consumption balance are simulated online, and a typical heat wave weather was selected. The results show that :(1) Installation of the attached solar roof can reduce 2m temperature by 0.29°C during the day, and the cooling effect is better than that of the scaffolding roof, but the drop of temperature at night is small. The scaffolding roof cools down to 0.23 °C during the day, and the effect of cooling at night is obvious. Compared with the ordinary roof, the temperature is lowered by 0.60 °C. (2) The solar roof can really cool down the city during the day, but it will also weaken the turbulence, inhibit the development of the daytime boundary layer and reduce the height of the boundary layer. In the case of strong turbulence development, the weakening effect of solar roofs is more obvious. (3) In addition to the impact of solar roof on urban meteorology, the most important thing is its contribution to energy. From the results, the power generated by solar panels can afford 54.5% of the energy consumption of air conditioners in commercial areas.
