摘要
本文将基于微热管阵列的光伏光热组件作为蒸发器与热泵技术相结合,提出了1种新型太阳能-空气双热源直膨热泵系统,对其运行性能进行了实验研究。研究表明,随太阳辐照的增加,其电效率和COP逐渐增加,热效率和综合效率逐渐降低;随环境温度的增加,其电效率逐渐降低,热效率、综合效率和COP逐渐增加。在供热工况下,太阳能-空气双热源模式更适合在低太阳辐照、高环境温度条件下运行;而太阳能单热源模式则更适合在高太阳辐照、低环境温度条件下运行。相比于燃气热水器、电热水器和空气源热泵热水器,该系统具有较好的经济性。
In this paper, a novel solar energy and air dual-heat-source direct expansion heat pump system is proposed by combining the photovoltaic-thermal module based on the micro heat pipe array as evaporator with heat pump technology, and its operational performance is experimentally studied. The results show that with increasing solar radiation, its electrical efficiency and COP keep increasing while its thermal efficiency and comprehensive efficiency are decreasing;with increasing ambient temperature, its electrical efficiency is decreasing while its thermal efficiency and comprehensive efficiency as well as COP are increasing. For heating, the solar energy and air dual-heat-source mode is suitable to operate under the condition of low solar radiation and high ambient temperature while the solar energy mode is suitable to operate under the condition of high solar radiation and low ambient temperature. Compared with gas-fired, electric and air source heat pump water heaters, the system is more economical.
