摘要
Abstract
In response to the severe issue of reduced driving range in electric vehicles under low-temperature conditions,this paper innovatively proposes a secondary condensation heat pump system and successfully integrates it into a real vehicle for experimental research.The results demonstrate that the energy consumption of this secondary condensation system is reduced by 60％compared to that of a high-voltage PTC system.Furthermore,an experimental study is conducted on the impact of the cooling fan duty cycle on the performance of the heat pump system.Both bench tests and real-vehicle performance indicate that when the cooling fan duty cycle is around 40％,the energy consumption of the heat pump system is optimal.Finally,the influence of the evaporator valve opening in the secondary condensation system on the heat pump system's performance is experimentally investigated.It is found that when the evaporator valve opening is controlled within the range of 40％to 60％,the energy consumption is optimized.关键词
