What is the Appropriate Temperature to Set the Car Air Conditioning in Winter?
2 Answers
The in-car temperature is best maintained between 18°C and 25°C, with a recommended temperature difference of no more than 10°C between the inside and outside of the vehicle. Here are some relevant details about car air conditioning: 1. Air Conditioning Components: Automotive air conditioning systems typically consist of a compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. 2. Working Principle: The electronic control unit will automatically operate the air conditioning system based on the settings made by the driver or passengers via the buttons on the air conditioning display control panel. It adjusts the air supply temperature and speed in real-time according to input signals from various sensors to maintain the optimal air environment inside the vehicle.
After driving for so many years, I find the most comfortable temperature for the air conditioning in winter is between 20 to 22 degrees Celsius. If it's set too high, like above 25 degrees, the car interior becomes too dry, making my skin feel tight and causing drowsiness, especially during long drives, which can lead to fatigue. On the other hand, if it's too low, around 18 degrees, it feels chilly and affects concentration. Personally, I prefer setting it at 20 degrees, which feels mild and refreshing. Also, remember not to set the fan speed too high—medium is best, as it avoids excessive noise. Use both the recirculation and fresh air modes: fresh air mode brings in outside air to prevent stuffiness, while recirculation mode heats up the car faster. When the windows fog up, the defogging mode of the air conditioning works best, with a moderate temperature to prevent repeated fogging. Regularly changing the cabin air filter ensures cleaner air and a better driving mood. This temperature range is worry-free, safe, and helps avoid catching a cold.
