摘要
通过对我国内蒙古地区的太阳能地源热泵系统运行模式及性能参数进行研究,得到适合该地区运行的最佳方式.以包头市住宅建筑为模型,建筑面积为6451.94 m^2,对该建筑的太阳能地源热泵系统的辅助模式与补热模式两种模式进行仿真,结果表明:辅助模式明显优于补热模式.集热器参数在最优条件下,太阳能地源热泵系统连续运行5a时,辅助模式下的土壤温度仅下降0.32℃.COP均值为4.82,辅助模式较补热模式的COP值提高24.9%.又分析了不同模式下的热泵机组制热量及系统的耗电量,辅助模式较补热模式下热泵机组的年制热量降低49.3%,年耗电量降低了4.26%.
Through the research on the operation mode and performance parameters of the solar-ground source heat pump system in Inner Mongolia in China,the best way to operate is obtained in this area.Taking a residential building,which covers an area of 6451.94 m^2 in Baotou as the model,the auxiliary mode and the supplementary mode of the solar-ground source heat pump system of the building are simulated.Results show that the auxiliary mode is obviously better than the heating mode.When the collector parameters under optimal conditions and the solar-ground source heat pump system is continuously operated for 5 years,the soil temperature in the auxiliary mode only decre ased by 0.32℃,the COP average is 4.82,and the assist mode increased by 24.9% as compared with the supplemental heat mode.Different modes of heating capacity of the heat pump unit and the power consumption of the system are aslso an analyzed.The auxiliary mode is reduced by 49.3%and annual electricity consumption decreased by 4.26%compared with the annual heat of the heat pump unit in the supplementary heat mode.
