Bus AC Low Pressure Fault Diagnosis and Repair Bus AC low pressure is a typical comprehensive fault signal, directly reflecting insufficient energy supply at the “suction end” of the refrigeration cycle. The first report in the 2025 *Commercial Vehicle Refrigeration System Diagnosis Yearbook*, titled “Multi-factor Coupling Analysis and Hierarchical Diagnosis Method for Low-Pressure Side Pressure […]
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 […]
Bus Air Conditioner Troubleshooting: A Systematic Diagnosis from Climate Adaptability to Passenger Experience Bus air conditioning is not merely a comfort device; it is a critical system concerning public health, operational efficiency, and urban image. Troubleshooting it requires transcending traditional technical boundaries and analyzing it within a broader context of urban ecology and passenger behavior. […]
