摘要
针对传统太阳能光伏光热PV/T双源热泵存在的热力性能差、能量损耗大等问题,提出一种光伏直驱PV/T双源热泵制热水系统(太阳能+空气源),并对系统进行实验研究。结果表明,在室外平均环境温度27.9℃、平均太阳辐射强度691.1 W/m2的夏天户外实验工况下,系统运行约4 h,将250 L 26.5℃的水加热到目标温度55℃,热泵平均COP为8.83。实验期间,PV/T光伏组件的平均温度比同样工况下的纯参比光伏组件温度降低9.8℃,光电性能相对提高17.53%。
In order to solve the problems of poor thermal performance and large energy loss of traditional PV/T(photovoltaic-thermal)dual-source heat pump,a photovoltaic direct-driven PV/T dual-source heat pump hot water system(solar+air source)is proposed in this paper,and the experimental study of the system is carried out.The results show that under the outdoor experimental conditions of the average outdoor ambient temperature of 27.9℃and the average solar radiation intensity of 691.1 W/m2 in summer,the system runs for about 4 h,the 250 L of water at 26.5℃is heated to the target temperature of 55℃,and the average COP of the heat pump is 8.83.During the experiment,the average temperature of the PV/T module is 9.8℃lower than that of the pure photovoltaic module under the same operating conditions,and the optoelectronic performance is relatively improved by 17.53%.
