What is the normal temperature for car air conditioning?
2 Answers
Car air conditioning temperatures vary depending on different conditions: 1. In summer, the temperature should be between 21°C to 25°C; 2. In winter, the air conditioning temperature should be between 25°C to 28°C; 3. The temperature difference between the inside and outside of the car should be within 10°C for passenger cars and between 8°C to 12°C for large buses. Car air conditioning, short for car air conditioning system, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to an optimal state. Its functions are: 1. To provide a comfortable riding environment for passengers and reduce travel fatigue; 2. To create good working conditions for the driver and ensure driving safety.
Having driven for over a decade, I mainly rely on two temperatures when using the air conditioning: one is the vent temperature. I've measured it several times with a thermometer. During summer cooling, the vent temperature is between 5-10°C, feeling icy and prickly to the touch. In winter heating, it needs to be at least 45°C or higher to warm my back. However, the more important factor is the perceived comfort. When driving, I prefer setting the temperature knob to around 22°C for optimal comfort—any lower and my arms get goosebumps, any higher and I start sweating. If the air isn’t cooling properly, it’s most likely due to refrigerant leakage or the condenser being clogged with dirt. Just last week, my car’s AC was blowing air like a fan because the cabin air filter hadn’t been changed for six months. Replacing the filter immediately restored the icy-cool airflow.
