Cool down in the cabin before turning on the air conditioner
Summer with high temperatures makes the interior of the car easily become hot if the car is parked for a long time in direct sunlight. At that time, the air conditioning system must work with high intensity to reduce heat, leading to fuel consumption and reduced cooling efficiency.
Therefore, limiting heat absorption into the car from the beginning is very important. Ideally, park the car in a covered place or in the shade. In case you cannot find a suitable location, the car owner can use a car cover or windshield cover. On the market, car covers usually cost about 300,000 - 500,000 VND, while windshield covers range from 80,000 - 150,000 VND.
In addition, heat-resistant film is also an effective solution to help reduce heat from sunlight. Good quality heat-resistant films usually have a lifespan of about 7 - 10 years before the heat-resistant effect decreases significantly.
Another simple operation is to open the car door for about 5-10 minutes before starting the air conditioner so that hot air in the cabin escapes. If you don't have much time, the driver can lower the window for 2-3 minutes and turn on the fan before activating the cooling mode.
According to Mr. David Bennett - a technical expert at the American Automobile Association, preliminary cooling of the car compartment will help the air conditioning system operate more efficiently. He said this helps reduce the load on the compressor and shorten the cooling time.
5 important notes to help car air conditioning operate effectively in the summer
First, park in a covered area or use a tarpaulin or windshield cover to limit heat absorption into the cabin.
Second, check and maintain air conditioners from the beginning of the hot season. According to technical recommendations, air conditioners and heaters should be maintained after about 20,000km. Air conditioner filters need to be checked after every 10,000km and replaced after 40,000km, while gas and gas filters should be checked after 20,000km and replaced after 50,000km.
Third, do not turn on the air conditioner immediately after getting into the car. You should open the door or lower the window to push hot air out before activating the cooling mode.
Fourth, do not direct the air vent directly to your body. Adjusting the air vent to the car ceiling will help cool air diffuse evenly in the cabin, helping the car cool down faster.
Fifth, turn off the air conditioner for about 5-10 minutes before turning off the engine but still let the fan operate. This operation helps take advantage of the remaining cold air, reduce fuel consumption and limit temperature differences between inside and outside the car.
Simple but proper usage habits will help the car air conditioning system operate more durablely, while bringing comfort to users on hot summer days.
