Study on the impact of different energy usage modes on Solar-Air source heat pump complementary heating system
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.
