摘　　要：目的为提高可再生能源利用率,研究太阳能空气源热泵耦合相变蓄热器供热系统实际性能,建立适合夏热冬冷地区民用住宅的节能供热系统。方法利用TRNSYS软件建立太阳能空气源热泵耦合相变蓄热器供热系统模型,并与太阳能空气源热泵供热系统进行对比分析,对两个系统从制热量、耗电量、能效比以及室内人体热舒适度四个方面进行模拟分析,使用PMV-PPD评价方法对两个系统的室内热舒适度进行评价。结果耦合相变蓄热器的供热系统耗电量低于无相变供热系统,节能率提高了13.29%;耦合相变蓄热器的供热系统平均能效比为3.5,太阳能空气源热泵供热系统的平均能效比为3.32,提高了5.14%;耦合供热系统可以为人体提供I级室内热环境水平的热舒适度,无相变供热系统只能为人体提供II级。结论太阳能空气源热泵耦合相变蓄热器供热系统节能性更好,系统能效更高,提高了可再生能源利用率,并且耦合供热系统在热舒适性方面优于无相变供热系统。In order to improve the utilization rate of renewable energy and establish an energy-saving heating system suitable for civil dwellings in hot summer and cold winter areas,the actual performance of solar airsource heat pump coupled phase change accumulator heating system is studied.A model of solar airsource heat pump coupled phase change accumulator heating system is established by TRNSYS software,and a solar air-source heat pump heating system set up as comparative object.The simulation results of the above two systems’four aspects-the heat production,power consumption,energy efficiency ratio,and indoor human body thermal comfort are analyzed.And the indoor thermal comfort of the above two systems is evaluated by the PMV-PPD evaluation method.The power consumption of the heating system with coupled phase change accumulator is lower than that of the heating system without phase change,and the energy saving ratio is 13.29%.And the average energy efficiency ratio of the former system is 3.5,and the latter system 3.32,which is an improvement of 5.14%.The former heating system can provide a class I level of indoor thermal environment for the human body,and the latter heating system can provide a class II level.So the solar air source heat pump coupled phase change accumulator heating system has better energy conservation,higher system energy efficiency,better comfort than that of the phase change free heating system,and improved renewable energy utilization.
