After a summer, I feel that turning on the air conditioner makes the driver spend a lot of money on gas. Which method is more fuel efficient to keep the inside of the car cool while driving? Roll down the windows, or turn on the air conditioner? Even if summer is coming to an end, it’s not too late to learn to make you cooler next summer. “Using the air conditioner to cool down while driving is more fuel-efficient than opening the windows to cool down, because the air conditioning system uses less fuel than the car against air resistance with the windows open.” Delphi Heat Exchange System Global President James Bertrand gave a professional answer.
Energy saving tips:
??When entering a car that is exposed to the sun, first temporarily fully open the windows to let the hot air out of the car, and then Close the windows, turn on the air conditioner, and let the cabin temperature drop. Press the recirculation button to recirculate cabin air through the air conditioner. ??When using a manual air conditioning system, the most energy-efficient method is to put the temperature control knob in the fully cold position and use the air volume control to adjust the temperature inside the car. Use the climate control knob to adjust the interior temperature only when the air volume control has been turned to the lowest position. ??If the cooling performance of the air conditioner decreases, the air conditioner should be inspected and maintained by an air conditioner professional. If the system is leaking, it should be repaired and the refrigerant replenished. After a few years of use, a small amount of refrigerant in the air-conditioning system will seep out from the hose, which is a normal phenomenon and needs to be replenished. ?? Air filters in car air conditioning systems can collect debris and obstruct airflow. The filter should be replaced at this time. The air filter in new production cars is located behind the glove box or under the windshield wiper and can be replaced by the owner or service personnel. See owner’s manual for service intervals.
??In addition to optimizing the car air conditioning system, when parking the car, try to park the car in the shade or use a reflective sunshade, and open the windows as much as possible on sunny days.
