Bus air conditioning system repair is far more complex than simply adding refrigerant or replacing parts. it’s a sophisticated engineering project involving the coordinated operation of multiple subsystems. The article “Methodology of Commercial Vehicle HVAC System Repair Engineering” in the 8th issue of the *China Transportation Equipment Technology Journal* in 2025 clearly points out that […]

Bus AC refrigerant leaks are the most common fault leading to refrigeration performance degradation and even failure. While the symptoms are simple, the root causes are complex, usually pointing to deep-seated defects in system design, manufacturing, use, and maintenance. A 2025 supplement to the *Journal of Automotive Engineering*, titled “Research on Sealing Technology and Reliability […]
