How to use car air conditioning in hot weather

(Baonghean.vn) - In hot weather, the air conditioning system must operate at full capacity when the vehicle is in operation. Therefore, using the air conditioner properly will help the vehicle operate more efficiently and save more fuel.

Do not turn on the air conditioner before starting the car.

When the car is not started and the air conditioner is turned on immediately, the battery will have to work to run the fan. If this happens frequently, the battery's life will decrease very quickly. When the engine is turned off without turning off the air conditioner, the battery will also be affected due to the sudden load. If the air conditioner is turned on immediately after starting the car, it will consume a lot of energy and take a long time to cool due to the hot air currents inside, and this will affect the life of the cooling system.

Therefore, you should start the car before turning on the air conditioner and turn off the air conditioner before turning off the engine. Start the car, open the doors to let the hot air escape from the car, after about 5 minutes of starting the car, turn on the air conditioner and adjust the wind level appropriately.

Roll down the car windows before turning on the air conditioner.

Lowering the car windows before turning on the air conditioner helps the heat in the car escape. Parts of the car such as the dashboard, leather seats, door panels and many other details are made of plastic. These details will give off an unpleasant smell when exposed to hot weather, lowering the windows will help the heat and unpleasant smell escape.

Therefore, before turning on the air conditioner, you should open the car windows, start the car and turn on the fan to blow all the hot air out for 5 minutes, helping the air in the car become airy. Note that you must roll up all the windows after the temperature in the car is suitable, to avoid letting the cool air escape and wasting fuel.

Do not let the temperature get too cold.

Low temperatures will consume more energy. However, more importantly, this can easily lead to a thermal shock reaction when the body steps out of the car. In addition, when using the air conditioner, you need to pay attention to the fan. If the fan is too strong, more energy will be consumed and the cold air blown by the fan can easily lead to negative effects on health.

Adjust the temperature properly

After performing the above steps, when turning on the air conditioner, you should adjust the cooling temperature slowly, do not set it at the highest cooling level, which will cause the condenser to work too hard. In addition, due to the temperature difference compared to the outside, the air conditioner will work too hard, leading to fuel consumption and quick damage. In addition, due to the temperature difference, getting in or out of the car will affect your health, such as getting a sore throat or a cold.

Adjust the wind appropriately after turning on the air conditioner

Adjust the fan mode appropriately when turning on the air conditioner, because when the fan is too high, it will consume electricity or cause discomfort when the wind blows strongly. If the fan is too low, it will lack the feeling of coolness. Therefore, it is necessary to adjust the cooling temperature slowly, should not be at the highest cooling level, will cause the condenser to work too hard.

You should adjust the air vent properly to avoid blowing cool air directly into your face, which can affect your health. You should also not blow air directly onto the glass, which will cause condensation on the car's glass.

Flexible use of air conditioning

Depending on the number of passengers, adjust the appropriate air conditioning capacity. Another tip is to let the air conditioner cool down slowly, avoiding the situation where this device has to change the temperature too low or too high suddenly.

According to research from the Department of the Environment (Australia), on average, the air conditioner consumes 10% of a car's fuel. When driving at speeds above 80km/h, you should turn on the air conditioner and close the windows to avoid wind resistance, which leads to more fuel consumption.

Turn off the air conditioning system when entering flooded areas.

In case of driving in the rain and flooded areas, you should turn off the entire air conditioning system to avoid dirt and water from entering and jamming the fan, damaging the air conditioning system.

Do not turn off the engine and air conditioner at the same time.

About 10 minutes before stopping the car, you should turn off the air conditioning system and open the windows to let the air escape before turning off the engine.

Regular air conditioning maintenance

Like the air conditioner in the house, the air conditioning system in the car also gets dust stuck on the filter and fan, causing blockage and preventing cold air from entering the car cabin.

Therefore, after a few months of use (this period depends on the level and conditions of use of the vehicle), the filter should be cleaned and replaced if necessary. According to the periodic maintenance standards of some car manufacturers, the air conditioner filter should be replaced after 20,000 km. If the weather conditions are harsh with lots of dust and humidity, the air conditioner filter should be replaced sooner.

In addition to cleaning the filter, you should check the high and low voltage wires and maintain the hot/cold coils of the air conditioning system and add refrigerant if it is lost.
