What is the appropriate temperature setting for a car's air conditioning?

The car's air conditioning in summer should be set to around 21°C to 25°C; in winter, it should be set to around 25°C to 28°C. The car air conditioning is a device that cools, heats, ventilates, and purifies the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Reasons for odors in car air conditioning: 1. When the air conditioning system operates, moisture in the air forms condensation on the surface of the condenser and evaporator, creating a breeding ground for mold, Aspergillus, Penicillium, and dust mites in the damp and dark air conditioning system; 2. Nicotine produced by passengers smoking in the car; 3. Odors emitted by rubber, plastic, and leather inside the car; 4. Smoke, dust, and exhaust fumes from the outside air entering the car.
My personal preference for car air conditioning settings is between 22 to 24 degrees Celsius, which feels most comfortable and energy-efficient. For example, on hot summer days when the outside temperature is high, I first lower it to 20 degrees for quick cooling, then raise it to 24 degrees to maintain a comfortable coolness—avoiding both fatigue and catching a chill. During long-distance driving, maintaining a stable temperature is crucial; too high can cause drowsiness, while too low can make hands and feet cold, affecting concentration. I've also noticed slight variations between different car models, but generally, this range works for most situations. From a fuel consumption perspective, moderate settings like 24 degrees save significantly more fuel compared to 18 degrees. For daily city driving, this setup is both practical and economical.
