加入轩辕同学 ， 成就新汽车人! 说到汽车热系统，汽车空调制冷剂的替代是一个绕不过去的话题。 薛庆峰表示，现阶段国内外对于汽车空调制冷剂替代的选择基本趋同：燃油车首选方案是HFO-1234YF，可能的备选方案是二氧化碳系统；新能 源汽车首选方案是R290二次循环系统，在此之前可能的过渡方案是混合工质。 作者 | 薛 庆 峰 （ 中 国 汽 车 工 业 协会 汽 车 热 系 统 分 会 秘 书 长 ） 设计 | 甄 尤 美 编辑 | 涂彦 平 "当前我们国家正在大力发展新能源汽车，但是欧美却把电动车发展的步伐放缓了。这使得我们汽车热系统整个行业被动地走到了风口浪尖，来 到了世界的前端。" 12月6日，在2025第十届新汽车技术合作生态交流会（WNAT-CES 2025）上，中国汽车工业协会汽车热系统分会秘书长薛庆峰在演讲中表示。 这自然给中国汽车热系统行业带来挑战——鲜有可以借鉴的成熟的技术，需要不断创新，自己去探索；同时也带来机遇——中国广阔的新能源 车市场为新产品提供了巨大的应用空间，为技术创新提供了大量的试错机会。 最后，他提到，希望有一套能够适用多种制冷剂的通用的汽车空调热系统，既能保持当下中国电动车低 ...
