What should the indoor car air conditioning temperature be set to in winter?
2 Answers
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.
