How to Properly Turn on the Car Air Conditioner in Winter?
2 Answers
Winter proper way to turn on the car air conditioner is: 1. Start the engine for preheating; 2. Turn on the heater when the engine coolant temperature reaches above 40°C; 3. Turn on the external circulation to expel cold air from the cabin; 4. Switch to internal circulation. The working principle of car air conditioning heating is: When the engine coolant becomes sufficiently hot, the refrigerant gas enters the condenser where its pressure and temperature decrease, causing the refrigerant gas to condense into liquid and release heat. Car air conditioning maintenance methods include: 1. Don't set the temperature too low; 2. Control the air outlet direction; 3. Avoid prolonged use; 4. Appropriately use high fan speed; 5. Turn off the AC when driving at low speeds.
Having driven for over a decade, I'm no stranger to winter AC issues. The correct approach is: Start the engine first and let it warm up for three to five minutes—only when it's warm will you get hot air. Don't turn on the fan immediately, or you'll get a blast of cold air. Then adjust the temperature knob to the heat zone and turn on the fan to defrost the windshield. If the fog is heavy, lightly press the AC button but keep the temperature higher—the compressor's dehumidification will make the warm air more comfortable. This prevents fogging that obstructs your view while saving fuel and electricity. Remember to use recirculation mode to trap the warm air; outside air intake will let in cold air. Regularly clean the AC filter, and your winter AC use will be smooth and pleasant, ensuring safe driving.
