Operation Simulation of Air Source Heat Pump Coupled Electromagnetic Energy System in Cold Region
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 CO2 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.
