What is the correct way to use car air conditioning and what precautions should be taken?

Correct usage of car air conditioning includes regularly activating it in winter, avoiding excessively long single usage sessions, and refraining from setting the temperature too low or too high for extended periods. Below are precautions regarding car air conditioning use: 1. Large temperature differences may cause colds: The ideal temperature inside the car should be about 5 degrees lower than the outside temperature. For example, if it's 35 degrees outside, set the air conditioning to around 30 degrees. Even if set to 18 or 20 degrees, the actual cooling capacity of the air conditioning may not reach that level. Instead, significant temperature differences can expose passengers to sharp contrasts between hot and cold, potentially leading to colds or fever. 2. Use both internal and external circulation modes: Some car owners use the internal circulation mode for prolonged periods to enhance cooling or heating efficiency. In this mode, air cannot naturally circulate between the cabin and the outside, making the cabin like a sealed, isolated space that maximizes air conditioning performance. However, this mode is not suitable for long-term use and should be alternated with the external circulation mode to prevent dizziness or chest tightness among passengers, which could lead to dangerous situations.
