Adjust the small flap at the air outlet to change the direction; move it parallel to the ground to close it. Below is relevant information about vehicle air conditioning: 1. Introduction: Vehicle air conditioning systems consist of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. They regulate cabin temperature and humidity to provide a comfortable environment for passengers. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the refrigerant's temperature and pressure increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy. The liquid refrigerant then flows through the throttle device, where its temperature and pressure decrease before entering the evaporator.
Once when I was on a long-distance coach, I found the overhead air conditioning too cold and wanted to turn it off. Actually, the operation is quite simple: there's often a round or square switch box above the armrest between the seats. Just press the button or turn the knob. Most coaches have this manual control. I often do this when traveling because prolonged exposure to the air conditioning can make you feel uncomfortable, and turning it off makes it much warmer. However, sometimes the switch can be hard to find, so you can ask your neighbor or glance at the corners of the ceiling. Remember to check if the air conditioning is properly turned off to avoid wasting electricity or causing malfunctions. An extra tip: if you're on a tour bus, there might be an adjustment lever at the top of the seat—just push it gently. In short, turning off the overhead air conditioning can make your ride more comfortable, especially on less hot days.
When driving a bus, passengers often ask how to turn off the overhead air conditioning. The usual method is to find a small switch next to the air conditioning unit installed on the ceiling—just press it to turn it off. The exact location depends on the vehicle model: for city buses, it might be above the seats, while for long-distance coaches, it's usually fixed on the handrails. Be gentle when operating it to avoid damage. For safety, wait until the system stops making noise after turning it off before leaving, as this ensures a longer lifespan for the air conditioning. Additionally, the bus's air conditioning is designed for even cooling, and frequent on/off switching can reduce efficiency, so I recommend lowering the fan speed instead. If the switch malfunctions, it might be a wiring issue—promptly inform the driver to address it and avoid safety hazards.
