摘要
光伏光热技术是太阳能的主要利用方式之一,太阳能光伏光热一体化(solar photovoltaic-thermal,PV/T)系统可实现系统产电和热量的双重效益。基于不同气候区的气候特征,以商场冷凝水耦合光伏/光热系统为研究对象。在确定制冷季冷凝水量的基础上,计算分析系统一次能源节约率及环境效益,研究该系统在不同气候区的适宜性。结果表明:在寒冷地区、夏热冬冷地区和夏热冬暖地区,PV/T系统比光伏(photovoltaic,PV)系统更加高效节能。在整个制冷季中,PV/T系统的发电量均高于PV系统,海口的发电效率提升了0.53%,拉萨的发电效率提升了0.11%;PV/T系统在海口地区一次能源节约率最高,达到59.62%;青岛CO_(2)减排量最高,总减排量达到5.5 t。
Solar photovoltaic-thermal(PV/T)technology is one of the main utilization of solar energy,the dual benefits of the system generation and heat are realized by solar PV/T system.Based on the climate characteristics of different climate zones,the condensed water coupling photovoltaic/photothermal system of shopping mall was taken as the research object.On the premise of determining the condensing water in the cooling season,the primary energy-saving rate and environmental benefit of the system were calculated and analyzed,and the suitability of the system in different climate zones was studied.The results show that PV/T system is more energy efficient than PV system in cold region,hot summer and cold winter region and hot summer and warm winter region.Throughout the cooling season,the PV/T system produce more electricity than the PV system,and the power generation efficiency in Haikou is increased by 0.53%,and that in Lhasa is increased by 0.11%.The primary energy-saving rate of 59.62%is the highest in Haikou,and the highest CO_(2) emission reduction of 5.5 t is observed in Qingdao.
