One of the features that is considered important for car users is AC. However, some people still do not know how AC works. Some people are still hesitant and worried about using or turning on AC in their cars. One of the most common concerns is that fuel consumption becomes very wasteful.
If the question is does AC really make fuel more wasteful? the shortest answer is yes. As the saying goes, there is never a free lunch. Likewise in the case of AC in cars. According to several studies, the use of AC can increase fuel consumption by 5% to 25%, depending on the conditions of use.
Why does AC affect fuel consumption in cars?
Of course, AC in cars does not work magically. The AC system is designed to remove heat from the car cabin and replace it with cooler air. This process creates additional load on the engine, which causes increased fuel consumption.
Factors Affecting Fuel Consumption When Using AC
Drivers and car owners need to know several factors that determine how much influence AC has on fuel consumption:
Outside temperature
As we know, the function of AC is to cool. Hotter temperatures can cause the AC to work harder. This process requires more fuel.
Condition of the AC system
A dirty AC system tends to consume more fuel. A dirty air filter or depleted refrigerant will work harder, increasing fuel consumption.
Driving speed
In fact, in traffic jams or slow driving, AC usage tends to be more wasteful because the engine is working less efficiently. Conversely, at high speeds on toll roads, the impact is smaller because the engine is working optimally.
Habits of AC usage
Turning on the AC at the lowest temperature setting continuously requires more energy. Turning the AC on and off frequently (repeatedly) can also burden the compressor.
Tips for saving fuel when using AC in a car
- Park in a shady place: Parking the car in a shady place can help lighten the work of the AC when it is going to be used. In addition to parking in a shady place, using a windshield protector can also reduce the heat in the cabin.
- Open the window: Before turning on the AC, it is a good idea to open the window first. This helps reduce the hot temperature inside.
- Air circulation mode: This mode allows the AC to cool the air that is already in the cabin, so it does not need to continuously draw hot air from outside.
- Set the appropriate temperature: Setting the temperature according to the size of the car will certainly make it easier for the AC compressor to work which will save fuel.
- Engine maintenance: Make sure the AC system is working properly. Clean the air filter regularly and refill the refrigerant if necessary.
Final Thought
Using AC will indeed consume more fuel. However, the level of amount can certainly be determined. By applying the tips above, you can make optimal use of your car's AC without sacrificing too much fuel efficiency. So, when hot weather strikes, don't hesitate to turn on the AC wisely!
