What is the optimal temperature for car air conditioning in summer?
1 Answers
Generally, it is recommended to set the temperature at 26°C, as the comfortable temperature range for the human body is between 24°C and 27°C. Additionally, consideration should be given to the local weather temperature, and the temperature difference between indoor and outdoor should not exceed 5°C. Here is some additional information: 1. Maintaining an appropriate temperature: The most comfortable air conditioning temperature for the human body should be between 24°C and 27°C, with the minimum not lower than 22°C. The indoor-outdoor temperature difference should not exceed 5°C, and the nighttime air conditioning temperature should not be set below 24°C. If the air conditioning is set too low, the indoor temperature may become excessively cold, increasing the risk of "air conditioning sickness," which can manifest as colds, coughs, fever, lethargy, and other symptoms. 2. Principles for more effective cooling: Based on the scientific principle that cold air sinks and hot air rises, the correct approach is to direct the air vents upward when cooling and downward when heating. This method enhances the cooling effect inside the car. Cars generally have good sealing, and if the vehicle is stationary with the windows closed and the air conditioning running while resting or sleeping, there is a risk of carbon monoxide poisoning from engine exhaust leaking into the cabin, which can be fatal. Therefore, during summer driving, proper air conditioning temperature settings and usage methods are crucial for health and safety, and maintaining a scientifically appropriate cabin temperature is essential.
