Analysis and Solutions to Bus AC Pressure Problems The stable operation of the bus air conditioning system is directly related to passenger comfort and driving safety. Abnormal pressure is a comprehensive fault signal, often involving multiple subsystems. This article draws on the research framework of the article “Fault Modal Analysis of Thermal Management System for […]

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 […]
