电动车CO_(2)热泵采暖参数优化研究

Optimization Study of Heating Parameters of CO_(2)Heat Pump for Electric Vehicles

文章基于自主设计的CO_(2)热泵系统,对影响热泵采暖功耗和COP的相关参数进行试验研究。在不同的环境温度下,调节压缩机转速、膨胀阀开度和鼓风机电压,对比热泵系统性能,整理出最优参数,以进行CO_(2)热泵系统的精确自动控制。

Based on the self-designed heat pump system,the parameters that affect the heating power consumption and COP of CO_(2)heat pump are tested.Under different ambient temperatures,the compressor speed,expansion valve opening rate and blower voltage are adjusted,the performance of the heat pump system is compared,and the optimal parameters are sort out for accurate automatic control of the CO_(2)heat pump system.
