What is the recommended temperature for car air conditioning in summer?
2 Answers
Generally, it is around 26°C. Below are the relevant details: 1. Composition: The car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. 2. Function: It is used to regulate the temperature and humidity inside the car, providing a comfortable environment for the driver. 3. Proper usage: The comfortable temperature range for the human body is between 24°C and 27°C. Additionally, the local weather temperature should be considered, and the indoor-outdoor temperature difference should not exceed 5°C. If the air conditioning temperature is set unscientifically in summer, leading to a large temperature difference between indoors and outdoors, it may cause air conditioning-related illnesses.
I've been driving for many years, and in summer, it's generally best to keep the temperature around 25°C. When I first start the car and it's sweltering outside, I set it to 22°C to cool down quickly, then raise it back to 25°C after about three to five minutes to maintain comfort. If it's set too low, like below 20°C, the AC will work overtime, not only increasing fuel consumption but also putting heavy strain on the engine, which can lead to long-term repair costs. It's also important to regularly clean the cabin air filter—dust buildup weakens airflow, making lower temperature settings ineffective. Remember, excessively low temperatures can be hard on the body, and the sudden temperature changes when getting in and out of the car can cause colds or headaches. I've stuck with this setup for over a decade, balancing comfort and efficiency, even on long drives. Checking the cabin air filter once a month is easy and worth it.
