What is the Suitable Temperature for Car Air Conditioning in Summer?
2 Answers
In summer, the most suitable temperature for car air conditioning is generally 26℃. Here is some relevant information: 1. Temperature difference between inside and outside: It is best to keep the temperature difference between the inside and outside of the car within 10℃. The most comfortable temperature for the human body is between 24℃ and 27°C. Additionally, the local weather temperature should be considered, and the indoor-outdoor temperature difference should not exceed 5℃. If the temperature difference between the inside and outside of the car is too large, it can easily lead to air conditioning sickness, with common symptoms including loss of appetite, nausea, and migraines. 2. Temperature set too low: Setting the temperature too low can increase the burden on the air conditioning system and reduce cooling efficiency. Moreover, keeping the air conditioning on for extended periods is not advisable, as it can lead to headaches—a common symptom of air conditioning sickness, primarily caused by a large temperature difference between indoor and outdoor environments. Choosing the right air conditioning temperature becomes a matter of knowledge.
In summer, I usually set the car air conditioning temperature between 22 to 24 degrees Celsius. This range feels most comfortable for the body—not too cold to cause joint pain or colds, nor too hot to make the skin sweaty and sticky. During long drives, temperatures below 18 degrees can easily lead to colds, especially for the elderly and children. Avoid directing the vents straight at the face to prevent headaches or dryness discomfort. For cars with automatic air conditioning, pressing the AUTO button will automatically adjust the fan speed and direction, making it efficient and convenient. A suitable temperature also helps maintain focus while driving, as extreme cold can cause physical tension and distraction. Combining the use of internal and external circulation is recommended—use internal circulation during midday to prevent external hot air from entering. Overall, a setting of 22-24 degrees is both comfortable and safe.
