Core Viewpoint - The Chinese automotive thermal system industry is at a critical juncture, facing both challenges and opportunities due to the global shift towards electric vehicles, while Western countries slow down their electric vehicle development [3][5]. Group 1: Challenges and Opportunities - The industry lacks mature technologies to reference, necessitating continuous innovation and exploration [5][6]. - The vast Chinese market for new energy vehicles provides significant application space for new products and ample opportunities for technological innovation [6][9]. Group 2: Refrigerant Replacement - The current consensus for refrigerant replacement in fuel vehicles is HFO-1234YF, with carbon dioxide systems as a potential alternative, while for new energy vehicles, R290 secondary circulation systems are preferred [9][10]. - The transition to natural refrigerants is emphasized, as they are considered more environmentally friendly compared to synthetic alternatives [9][10]. Group 3: PFAS Legislation - The PFAS legislation has undergone significant changes, extending the exemption periods for both electric and fuel vehicles, which indicates a longer timeline for the implementation of refrigerant replacements [12][10]. - The legislation signals that the industry still has time to adapt and develop suitable alternatives, with HFO-1234YF remaining the primary choice for fuel vehicles [12][10]. Group 4: Standardization and Innovation - The establishment of a robust standardization system is crucial for the application of new technologies, with the industry encouraged to develop its own standards for refrigerants [13][10]. - Collaboration with various organizations is being pursued to create industry standards that support technological innovation and application [13].
