Characterization and evaluation of a novel heat pump scheme for heating of electric vehicles

对包括混合动力、插电式混合动力和电池电动汽车在内的电动汽车(EV)的兴趣在 最近几年。然而，任何进一步的增长都将取决于通过修改 材料、制造和组装工艺，并增加了充满电的行驶里程 电池。与内燃机不同，电动汽车在寒冷的冬季条件下供暖是具有挑战性的，因为缺乏 电动汽车传动系产生的废热和暖通空调系统的高电耗。小说 因此，应该制定办法，为电动汽车提供高效的供暖和制冷。一部小说和 改进型热泵系统，由Réseau Azra公司制造并获得专利，可提供更高的热泵系数 通过对蒸发和冷凝空气进行预处理来提高性能(COP)，从而提高整体 系统的警察。本项目的目标是测量、模拟和评估该系统的性能 该系统适用于不同驾驶条件下电动汽车的典型加热和冷却要求。然后，通过 使用这一阶段的结果作为基准，将有可能评估该系统的电动汽车暖通空调和 确定使该系统适应实际电动汽车所需的修改。

Interest in electric vehicles (EVs) including hybrid, plug-in hybrid and battery electric vehicles has increased in recent years. However, any further growth will depend on cost reductions through modifications in the material, manufacturing and assembly process and also increase of the driving range with fully charged batteries. Unlike combustion engines, heating of EVs is challenging in cold winter conditions due to the lack of waste heat from the EV drive train and high electric power consumption of the HVAC system. Novel approaches should therefore be developed to provide efficient heating and cooling for EVs. A novel and modified heat pump system, built and patented by Réseau Azra Company can provide higher coefficient of performance (COP) by pretreatment of the evaporation and condensation air and hence, increasing the overall COP of the system. The objective of this project is to measure, simulate and evaluate the performance of this system for the typical heating and cooling requirements of EVs under different driving conditions. Then, by using the results of this phase as a benchmark, it will be possible to evaluate this system for EV HVAC and identify the required modifications to adapt this system to an actual EV.
