2 Answers
Winter car heater activation method is: 1. Press the one-touch start button to start the vehicle; 2. Press the AC option to activate the air conditioning system; 3. Rotate the knob arrow to the red zone; 4. Adjust the digital display to set the wind power level. Car heater working principle: 1. The compressor inhales low-temperature and low-pressure refrigerant gas from the evaporator outlet; 2. Compresses it into high-temperature and high-pressure gas discharged from the compressor, reducing pressure and temperature; 3. The refrigerant gas condenses into liquid, releasing a large amount of heat. Functions of car air conditioning: 1. Interior temperature regulation; 2. Humidity regulation; 3. Airflow regulation; 4. Air purification.
In winter when using the car heater, I usually start the engine and let it warm up for a few minutes until the coolant temperature rises. Avoid turning the fan to maximum immediately to prevent overloading the engine. Then turn the temperature control knob to the hottest setting, starting with medium or low fan speed and gradually increasing it. It's best to direct the vents toward the windshield and footwell area for both warmth and anti-fogging effect. Turning on recirculation mode heats up the cabin faster, but remember to switch to fresh air mode periodically to prevent stuffiness. Don't forget to check if the coolant level is sufficient - regular system maintenance will prevent issues. Safety first: keep visibility clear by preventing window fogging for more secure driving.
