With the harsh summer sun, cooling down your car quickly, especially when it has to be parked for a long time under the scorching sun, becomes a top priority. For cars, the air conditioning system, which is considered standard equipment, becomes more essential than ever.
However, air conditioning does not always work immediately, especially when you park your car under the hot sun for a long time. Below are simple, effective tips that you can easily apply to quickly cool down your car, even when the car is parked under the sun.
Using a Car Door as a Fan: Exploiting the Pressure Effect
Here is a useful and scientifically based tip regarding the movement of liquids and gases. It is simple to do as follows:
- Open the rear passenger door.
- Then quickly open and close the driver's door continuously about 5 - 10 times.
This creates a low-pressure area that quickly “sucks” hot air out of the car. Fresh air from outside will rush in through the open door, lowering the temperature inside in just a few seconds. This is a simple but extremely effective way to “blow off the heat” before you get in the car.
Activate the outside air intake mode instead of turning on the air conditioner immediately
When your car is too hot, turning on the air conditioner right away won't cool it down as quickly as you think. Instead, take advantage of the outside air intake mode, which brings air from outside into the car through the fan system.
How to do it:
- Turn on the fan at high level and switch to outside air intake mode.
- When the outside air is cooler than the inside, it helps push hot air out of the car.
After a few minutes, when the temperature in the car has dropped, you can switch to recirculation mode to keep the cool air circulating more effectively.
Roll down all windows when starting to drive.
If you can't use the "door fan" trick, the simplest way is to open all the windows as soon as you get in the car.
Because when the car is moving, the outside air will circulate strongly through the interior compartment, helping to quickly push hot air out and suck cool air in. This is an effective method and does not require any supporting equipment.
Lower the window slightly when parking.
A small but effective tip to prevent your car from overheating in the first place when parked in hot weather is to slightly lower the windows about 1 - 2 cm when parking.
Because completely closed glass doors will cause hot air to be trapped and the temperature will rise higher.
When there is a small gap, the pressure inside the car is reduced, allowing hot air to escape.
