| 在“双碳”目标指引、《<蒙特利尔议定书>基加利修正案》正式生效的背景下，大力发展氢燃料电池汽车已然成为交通载运领域实现节能减排、助力碳中和的重要方案之一。然而，目前的氢燃料电池汽车存在工作温度区间窄、热管理工质温室效应、热管理系统相对独立而导致效率较低等问题。针对上述问题，本文文提出一种基于跨临界CO2技术的热泵空调热管理一体化系统，利用多种控制算法，实现整车级别内乘员舱与质子交换膜氢燃料电池的综合热管理方案，应用AMESim系统建模仿真平台进行模型搭建，并综合分析仿真结果。结果表明：该新型热管理系统可保证在任意行驶条件下，乘员舱和电池模块快速达到理想温度并保持稳定，且在全工况范围内具有更佳的能量利用效率，相比于传统独立热管理系统更加高效节能。 |

| Abstract: |
| Carbon peaking and carbon neutrality goals have been set, and the Kigali Amendment to the Montreal Protocol has officially come into force. The vigorous development of hydrogen fuel cell vehicles has become an important means of energy conservation and emission reduction in the transportation sector. Nevertheless, current fuel cell vehicles have problems including a narrow operating temperature range, the greenhouse effect produced by the thermal management working fluid, and low efficiency owing to the independent thermal management system. Thus, based on a transcritical CO2 heat pump, a novel thermal management scheme was proposed that uses multiple control algorithms and combines the thermal management systems of vehicle cabins and proton exchange membrane fuel cells (PEMFC). AMESim was used to simulate this system. After a comprehensive analysis, the results showed that the integrated thermal management system can ensure that the cabin and battery quickly reach and maintain their respective ideal temperature. Compared with a traditional independent thermal management system, the new system has better energy utilization efficiency over the entire operating range, with greater overall efficiency and energy savings. |
