How to Turn Off the Overhead Air Conditioning in a Bus?

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.
