Especially in hot summer days, users often choose to start the car and turn on the air conditioner for 5 – 10 minutes before getting in the car.
Does starting the car and turning on the air conditioner consume fuel?
The answer is yes, because when the car starts but does not move, the engine is still running and all the functions of the car are performed through the operation of the engine. This leads to fuel consumption.
Not only with gasoline-powered cars, but also with electric cars, starting the car and turning on the air conditioner also consumes electricity. So whether you use a gasoline/diesel car or an electric car, starting the car and turning on the air conditioner also consumes energy.
Fuel consumption when starting the car and turning on the air conditioner
The amount of fuel consumption when starting the car and turning on the air conditioner varies depending on the car model and the usage mode of the car. For example, whether you turn on the A/C or not, turn it on at a low or high setting, turn on the fan or not… all make a difference.
Starting the car and turning on the air conditioner will consume fuel. (Illustrative image).
A fuel consumption test when starting the car and turning on the air conditioner was conducted under the following assumed conditions:
Ambient temperature: 40 degrees Celsius
Air vent temperature (air conditioner): 20 degrees Celsius, driver seat temperature 24 – 25 degrees Celsius
Solar radiation energy: 1000W/m2
The result is that when the car is not running and only the air conditioner is turned on, it consumes 0.352 liters of gasoline. In reality, the energy consumption for starting the car and turning on the air conditioner while the car is stationary will be much higher than when the car is moving. Specifically (applying the above assumed conditions):
This number may vary with different usage conditions such as car model, engine, generation, and temperature…
Does starting the car and turning on the air conditioner harm the car?
This is a controversial issue with some information stating that it has an impact and harms the car, while others say it does not.
However, many studies in the United States have shown that turning on the air conditioner when starting the car and not driving does not have an impact on the car engine. This is because current car models are equipped with automatic ECUs to automatically adjust the system to optimize the engine operation. When we start the engine, the support systems in the car will automatically turn off to focus on fuel and electricity for operation.
This intelligent operation has helped the car not be damaged even when the air conditioner is turned on without driving.
Should you start the car and turn on the air conditioner?
You should only start the car and turn on the air conditioner for a short period of time or to cool down the car.
Absolutely, do not start the car and turn on the air conditioner and sleep. In reality, many people have encountered danger and death from turning on the air conditioner to sleep due to lack of oxygen.
