摘　　要：随着能源消耗的持续增加和环境问题的日益严重,开发和利用可再生能源成为了当今世界的一项重要议题。太阳能作为一种清洁、可再生的能源,其在供暖和制冷系统中的应用受到了广泛关注。呈现一种太阳能-空气源热泵辅助水源热泵的复合供热系统,以应对系统性能下降的问题。利用TRNSYS软件建立太阳能-空气源辅助水源热泵的复合系统和传统的太阳能-空气源热泵系统,模拟这两种系统在供暖季的运行情况。结果表明:在12月25日复合系统比传统系统日平均COP高19.88%,耗电量减少278.08kWh,并且复合系统全年运行中太阳能集热器供热量占总供热量的51.8%,所有热泵供热量占48.2%。此外,对系统能效比(COPsys)、逐月耗电量进行对比分析,与太阳能-空气源热泵传统系统相比,该复合系统的能效比提高了25.78%,电耗降低了22.61%。整体而言,该复合系统节能效果显著,这一研究为西藏地区太阳能热泵系统的设计和运行提供了理论依据和技术支持。With the continuous increase in energy consumption and the escalating severity of environmental issues,developing and utilizing renewable energy has become an important global issue.Solar energy,as a clean and renewable form of energy,has received widespread attention for its applications in heating and cooling systems.This study presents a solar-assisted air source heat pump coupled with water source heat pump composite heating system to address the problem of system performance decline.Using TRNSYS software,models were built for both the solar-air source assisted water source heat pump composite system and the traditional solar-air source heat pump system to simulate their operation during the heating season.The results show that on 25 December the composite system had a 19.88% higher average daily COP than the conventional system and consumed 278.08kWh less electricity,and that the composite system operated throughout the year with solar collectors supplying 51.8% of the total heat and all the heat pumps supplying 48.2% of the total heat.In addition,comparisons were made between the two systems' coefficient of performance(COPsys) and monthly electricity consumption.The results indicated that compared to the traditional solar-air source heat pump system,the COP of the composite system improved by 25.78% while electricity consumption decreased by 22.61%.Overall,this composite system demonstrated significant energy savings,providing theoretical support and technical assistance for the design and operation of solar thermal pump systems in Tibet.
