What is the optimal temperature for car air conditioning?

The temperature difference between the car interior and the external environment should not be too large, as it may cause discomfort. Generally, it is recommended to maintain a temperature difference within 10°C for passenger cars and 8-12°C for large buses. The car air conditioning temperature can be adjusted according to the season, with specific recommendations as follows: 1. In summer, set the air conditioning to 21-25°C. 2. In winter, set the air conditioning to 25-28°C. Additional information about car air conditioning includes: 1. Car air conditioning: This refers to the air conditioning system installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Components: The system includes refrigeration units, heating units, and ventilation units, all of which are designed to make efficient use of the limited space inside the car.

I always find the air conditioning temperature set between 22 to 24 degrees Celsius most comfortable. After years of commuting by car and trying various temperatures, I've discovered this range keeps me from sweating profusely or shivering from cold. During summer heat, setting it lower to 20 degrees may feel cooler but increases the risk of catching a cold and raises fuel consumption. In winter, setting it above 25 degrees is rather energy-inefficient. Maintaining a neutral temperature helps keep the body in good condition, enhancing driving focus. I've also noticed that occasionally switching to auto mode allows the system to balance the temperature automatically, saving both hassle and fuel. On long trips, smaller temperature variations result in fewer passenger complaints. The key is to fine-tune based on personal comfort, avoiding extreme settings.

Based on my years of experience in car repair, the optimal temperature for car air conditioning is between 22 to 25 degrees Celsius. Setting it within this range ensures moderate compressor and engine load, avoiding excessive wear on components and prolonging the AC's lifespan. Temperatures too low, such as below 18 degrees, increase fuel consumption and risk of malfunctions; while temperatures too high, like above 26 degrees, result in poor cooling performance. I personally prefer setting it at 23 degrees for smooth operation and low noise. Adjust slightly when external conditions vary significantly, but avoid temperature differences exceeding 10 degrees. Regular checks of filters and refrigerant are also crucial, as even the best temperature settings won't perform well without proper maintenance. Maintaining a reasonable temperature protects your car's health and ensures safe driving.

When taking kids out, I always set the air conditioning to around 24°C. This temperature prevents them from catching a chill or getting fussy, and everyone stays comfortable together. Large temperature differences, like 35°C outside and 18°C inside the car, can cause discomfort when getting in and out, making kids more prone to illness. For long summer trips, setting it slightly higher at 25°C saves energy while maintaining comfort. After setting the temperature, keep the fan speed moderate—not too strong to avoid discomfort—and use the external circulation mode to bring in fresh air and keep the cabin pleasant. A stable temperature makes family trips much more relaxing.
