摘　　要：风冷热泵在空调制冷行业得到广泛的应用,但在寒冷的北方制热效率严重降低。为解决以上问题,本文设计了液体搅拌和涡电流联动式辅助供热系统,将风能转化为热能,提高热泵供暖温度。理论分析和实验数据对比结果得出磁极对数、转速和液面高度对该系统制热效率影响较大。当风速低于7 m/s时,主要依靠液体搅拌制热;风速高于13.5 m/s时,液体搅拌制热和涡电流制热同时启动,效率提高了40%。Air-cooling heating pump are widely used in the air-conditioning and refrigeration industry,but the heating efficiency is severely reduced in the cold north.In order to solve the above problems,an auxiliary heating system with liquid agitation and eddy current linkage is designed to convert wind energy into heat energy and to increase the heating temperature of the heat pump.The comparison between theoretical analysis and experimental data shows that the number of magnetic pole pairs,rotation speed,and liquid level height have a greater impact on the heating efficiency of the system.When the wind speed is lower than 7 m/s,the liquid stirring heating is mainly used.When the wind speed is higher than 13.5 m/s,the liquid stirring heating and eddy current heating are started at the same time,and the efficiency can be improved by 40%.
