The global push for carbon neutrality has accelerated the low-carbon transformation of the bus air conditioning industry, bringing both opportunities and challenges to practitioners. This shift is not just a response to environmental policies, but also a key driver to meet the evolving needs of bus operators and urban public transport systems.
Natural refrigerant technologies, represented by CO₂ air conditioning systems, have become a core focus of industry innovation. Compared with traditional refrigerants, CO₂ boasts outstanding environmental performance—with zero ozone depletion potential and extremely low global warming potential—fully aligning with the strictest environmental standards in various regions. In practical applications, these systems also show advantages in energy efficiency, especially in extreme temperature conditions: they maintain stable cooling capacity in high-temperature environments and reduce energy consumption in mild climates, helping bus operators cut long-term operating costs.
However, the low-carbon transformation still faces practical hurdles. For instance, the high initial R&D and production costs of new refrigerant systems need to be balanced with market acceptance; meanwhile, technical upgrades for adapting to different bus models and regional climate characteristics require continuous input.
Looking ahead, the industry must deepen collaboration between technology R&D, production, and market demand. By optimizing product performance based on real operational scenarios and promoting the popularization of low-carbon solutions through policy guidance and market education, we can truly drive the bus air conditioning sector toward a greener, more sustainable development path.
