Bus Air Conditioning Airflow Diagnosis and Optimization Bus air conditioning airflow is the carrier of heat exchange and distribution; its organizational efficiency directly determines temperature control accuracy, comfort, and energy consumption. Poor airflow distribution is a major cause of passenger complaints about “stuffy heat, direct cold airflow, and odor diffusion.” According to data from the […]
Bus Air Conditioner Fan Motor Fault Analysis and Solutions Bus air conditioner fan motor is a core component for efficient heat dissipation in air conditioning systems, and its performance directly determines system pressure, cooling efficiency, and operational reliability. A study published in the 2025 issue of the quarterly journal *Commercial Vehicle Thermal Management Technology*, titled […]
Bus AC not blowing air is a common but directly impactful malfunction, involving multiple subsystems including power, control, mechanics, and operation. An article titled “Failure Mode Analysis of Commercial Vehicle HVAC Air Supply System,” published in the 12th issue of the *China Transportation Equipment Technology Journal* in 2025, points out that “approximately 70% of ‘no […]
Bus AC fan not working will directly cause air conditioning failure and may trigger a chain reaction of problems such as high system pressure and compressor damage. The bus air conditioning fan (including the condenser fan and evaporator blower) is a core component ensuring heat exchange efficiency, cooling effect, and system safety. The first issue […]
