What is the optimal temperature setting for car air conditioning in summer?
2 Answers
In summer, the optimal temperature setting inside the car is generally 26℃. Below is relevant information about summer car temperatures: 1. Reasons: (1) The healthiest temperature difference between inside and outside the car is within 10℃. (2) The most comfortable air conditioning temperature for the human body should be between 24℃ and 27℃, with a minimum not lower than 22℃. The indoor-outdoor temperature difference should not exceed 5℃, and the air conditioning at night should not be set below 24℃. 2. The correct way to use car air conditioning in summer: The proper method is to first open all four windows to allow cross-ventilation, helping the cabin temperature to quickly equalize with the outdoor temperature. Then, close the windows and turn on the air conditioning with the internal circulation for cooling.
I think setting the summer car air conditioning temperature depends on comfort. Having driven for many years, I generally recommend keeping it between 22 to 25 degrees Celsius for optimal comfort. Too low, like 18 degrees, not only increases the risk of catching a cold but also makes the airflow from the vents too strong, feeling like an ice cave. On the other hand, too high, like above 30 degrees, becomes stuffy and can distract from driving. My habit is to start with maximum fan speed for quick cooling, then stabilize around 25 degrees. Also, be mindful of not creating too large a temperature difference to avoid catching a cold from frequent temperature changes. By the way, for cars with automatic air conditioning, pressing the AUTO button adjusts it automatically, but manual temperature adjustment is more precise. The goal is to feel cool but not shivering, balancing health and energy efficiency.
