摘要/Abstract

摘要： 研究了一种平板型太阳能光伏/光热一体化热泵(PV/T-HP)系统,制冷剂R134a直接在太阳能光伏板背面盘管内吸热而蒸发,以降低光伏电池工作温度,保证其高效稳定地输出电能;集热器同时作为蒸发器,所收集的热量经热泵循环进行温度提升,为建筑提供生活热水、供暖和驱动制冷空调。对平板型PV/T-HP热水系统在南京室外的一个夏季晴天工况下循环加热180 L水至60℃进行了实验研究,探讨了太阳总辐照度、光伏/集热器工作温度以及光电输出控制方式对系统光电、光热综合输出特性的影响规律;对比实验得出了在热电联供模式下,系统发电量比无冷却的单一光电输出模式下相对高出35%。

Abstract: A solar photovoltaic/thermal integrated heat pump (PV/T-HP) system was proposed. Refrigerant,R134a flowing inside the tubes below the PV cells,absorbs the solar heat and evaporates.The heated water produced by heat pump could be used to supply domestic hot water services combined with space heating,or to assist solar cooling system in buildings.The system’s thermodynamic and photovoltaic output characteristics for heating 180 L water up to 60℃ were investigated experimentally on a summer sunny day in Nanjing,China.The performances of the prototype for both electricity generation and water heating vs that for electricity generation only were compared.Results show that,the performance of PV cells without cooling is deteriorated greatly at noon,because of its higher working temperature.While for the PV/T-HP system,the cells is operated on a stable and uniform temperature condition,and therefore output more electricity by 35%.

Key words: solar-assisted heat pump, photovoltaic/thermal, collector/evaporator, photovoltaic characteristics
