Bus AC pressure problems are a clear manifestation of a fault, but not the root cause itself. Pressure is the “blood pressure” of the refrigeration system; its high and low pressure readings directly reflect the overall state of energy flow and heat exchange within the system. A special paper published in the 2025 *International Automotive […]

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 […]
