摘要
太阳能-空气源热泵互补供热系统在农村地区得到了应用,而农村人员的用能模式与城市居民具有较大差异.为定量探讨不同用能模式对系统的影响,以全生命周期费用和碳排放量为目标函数,利用TRNSYS软件构建了系统仿真优化模型,优化了不同用能模式下的系统设备容量,定量评价了不同用能模式下的系统COP、太阳能保证率、全生命周期费用和碳排放量.结果表明,与固定室温模式相比,采用动态室温控制模式下的集热器面积和水箱体积明显减少,而用能模式的不同对系统碳排放量的影响最大.研究成果揭示了不同用能模式对太阳能-空气源热泵互补供热系统的显著影响,可为今后农村地区系统的应用及优化研究提供参考依据.
Abstract
The complementary heating system of solar-air source heat pump have been applied in rural areas,where the energy usage pattern of rural residents differ significantly from those of urban dwellers.To quantitatively explore the impact of different energy usage patterns on the heating system,a system simulation optimization model is constructed using TRNSYS software,with life-cycle cost and carbon emissions as objective functions.The model optimizes the system equipment capacity under different energy usage patterns and quantitatively evaluated the system's COP,solar fraction,life-cycle cost,and carbon emissions under these patterns.The results indicate that the collector area and water tank volume are significantly reduced under the dynamic indoor temperature control mode compared to the fixed indoor temperature mode.Furthermore,the impact of different energy consumption patterns on the system's carbon emissions was found to be the most significant.
