What is the appropriate temperature setting for car air conditioning?

[AvaDella]

It is suitable to set the car air conditioning temperature between 18°C and 25°C, with a temperature difference of less than 10°C between the inside and outside of the car being ideal. Relevant information is as follows: 1. Human body: The comfortable temperature range for the human body is 20°C to 25°C. Above 28°C, people will feel hot, while below 14°C, they will feel cold. 2. Temperature: Car air conditioning engineers suggest that in summer, the temperature can be set between 21°C and 25°C, and in winter, between 25°C and 28°C. They also recommend that the temperature difference between the inside and outside of the car should not be too large, as it may cause discomfort to passengers. Generally, the temperature difference should be within 10°C for cars and 8°C to 12°C for large buses.
