In winter, the most suitable temperature setting for car air conditioning is between 18℃ and 20℃. Here is relevant information about car air conditioning: 1. The function of car air conditioning is to adjust and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to an optimal state. It also provides a comfortable environment for passengers, reduces travel fatigue, creates good working conditions for the driver, and serves as a crucial ventilation device for ensuring safe driving. 2. Car air conditioning consists of components such as the compressor, condenser, evaporator, expansion valve, receiver-drier, and piping. 3. Car air conditioning generally includes cooling devices, heating devices, and ventilation devices. These combined systems make full use of the limited space inside the vehicle, featuring a simple structure and ease of operation.

In winter, setting the car air conditioning to around 22°C is most suitable. Higher temperatures like above 25°C can easily make people drowsy, especially during long-distance driving, where dozing off poses a safety hazard. I usually start the vehicle and turn on the cold air to defog the front windshield first. Once the glass is clear of fog, I adjust the temperature to around 20°C. If there are children in the car, slightly increase the temperature but keep it below 23°C, otherwise kids may sweat and become fussy, which can distract the driver. In terms of fuel consumption, 25°C uses about 10% more fuel than 20°C, saving both money and resources. Overall, a range of 20-22°C keeps you warm without wasting fuel.

I usually set my car's air conditioning between 20-22°C while driving, which feels just right - not too hot or cold. Higher settings make it dry and hot, while lower ones feel chilly. Especially on winter mornings, I start at 20°C when the engine is warming up, then gradually increase it. Maintaining good air quality is important, so I regularly switch between recirculation and fresh air modes to prevent stuffiness. A fuel-saving tip is to avoid excessively high temperatures - setting 25°C consumes significantly more fuel than 20°C, which adds up financially over time. Ultimately, make minor adjustments based on personal comfort, but don't be too reckless with extreme settings.

In winter, it's safest to keep the car's air conditioning below 22°C, as higher temperatures can cause drowsiness and affect driving. I prefer starting at 20°C and increasing to 22°C after a 10-minute warm-up for short trips. Temperature settings are linked to fuel consumption; experiments show that a 5°C increase can raise fuel usage by 15%, hitting both your wallet and fuel efficiency. Don't forget the defogging function: use cold air to blow on the windshield for a few minutes to clear fog before adjusting the temperature, ensuring clear visibility. Personal preferences vary, but avoid exceeding 24°C.

Setting the car air conditioner to around 22°C in winter is ideal—mild and comfortable without being stuffy. I've tried higher temperatures like 26°C, but driving for just an hour made me feel drowsy. When starting the car, first activate the auto mode to defog, then adjust to a range of 20-22°C once stable. Families with young children should avoid setting it too high, as 25°C can make little ones sweat and fuss. From an eco-friendly perspective, lowering the temperature by even one degree saves fuel, promoting low-carbon travel. It’s all about balancing health and energy efficiency.
