摘　　要：目的 为了促进空气源热泵耦合电磁能供热系统在严寒地区住宅建筑中的应用,研究该系统的运行性能和稳定性。方法 以沈阳地区某住宅建筑为例,应用Trnsys软件建立了空气源热泵耦合电磁能供热系统仿真模型,并用实测值对模型进行了验证;深入探讨空气源热泵耦合电磁能供热系统在供热期的运行特点,并与空气源热泵和电磁能供热系统分别进行比较。结果 空气源热泵耦合电磁能供热系统模型可靠,相对误差可以控制在15%以内;在供热期,室内平均温度可保持在17.97~21.84℃;空气源热泵耦合电磁能供热系统比电磁能供热系统的COP提高了59.17%,空气源热泵耦合电磁能供热系统CO_(2)减排量比空气源热泵和电磁能供热系统分别提高1.47%和59.50%。结论 空气源热泵耦合电磁能供热系统运行和COP变化更为稳定,系统环境效益更佳,室内热舒适性更高。In order to promote the application of air source heat pump coupled electromagnetic energy heating system on residential buildings in the cold area,the performance and stability of the system is studied.A residential building in Shenyang taken as an example,a simulation model of the air source heat pump coupled electromagnetic energy heating system is established by Trnsys software and verified by the measured values.Then operating characteristics of this system during the heating season were thoroughly discussed,and compared with air source heat pump and electromagnetic energy heating system respectively.The results show that this simulation model is reliable,and the relative error of the simulation results can be controlled within 15%.During the heating season,the average indoor temperature can be maintained at 17.97~21.84℃;the COP of the air source heat pump coupled electromagnetic energy heating system increases by 59.17%than that of the electromagnetic energy heating system,and the CO 2 emission of the air source heat pump coupled electromagnetic energy heating system is reduced by 1.47%and 59.50%compared with the air source heat pump and electromagnetic energy heating system respectively.So the operation and COP change of the air source heat pump coupled electromagnetic energy heating system are more stable than that of other two systems,its environmental benefit is better,and the indoor thermal comfort is higher.
