Tricks to use car air conditioning in the most efficient way

Summer, 40 degrees in the shade and desire to return home to throw us the deserved nap that we all deserve when we come from taste a paella. The same one that can be indigented if we ride in the car and do not apply some simple tricks to cool the cabin as soon as possible. Here is the difference between cope with the return home or make the car seat a real hell.

First of all, be foresee. You cannot always but it is evident that the longer the car passes in the shade, the better it will go later. Keep in mind that if there are extreme temperatures on the street, these are much higher inside our car, overheated without an escape to come out all that hot air.

Therefore, before leaving the car to his fate, he tries to leave it under a shadow and, whenever possible, with the parasol placed. The RACC calculates That when the sun makes its own, the interior temperature of the car can rise at up to 20 degrees. Especially in those cars with black upholstery. Then, A parasol helps reduce temperature Interior in up to 11 degrees, what we like to reduce the suffocating heat as soon as possible.

Also, small Offtopic, Heat can damage the dashboard materials. The windshield makes of magnifying glass and the temperature that the upper plastics reach can be very high. With a parasol we will reduce the risk of premature wear such as the steering wheel “peel” and lose part of the plastic or break the leather that covers it.

The Japanese “trick”. Some time ago what was called as “the Japanese trick” was viral. The truth is that I could carry the word “trick” but The Japanese thing seemed a bit free. Anyway, the case is that it works.

If you get to the car and you are burning, it is a good idea to lower the windows and open the doors for a few minutes. Thus the hot air will escape little by little from the inside. To accelerate this process, what we can do is take a couple of doors and “fan” with them the car. Moving them with some momentum we will generate a current of air that will lower the temperature faster.

“The first thing, go down the windows”. If, on the contrary, you want or need to get the car as soon as possible, Juan José, one of the Ebenezer workshops mechanics that follow more than 300,000 people in Tiktok, more than 300,000 people, recommends That “the first thing, when riding you, is to lower all the windows of the car.”

The council follows the same logic that before but is applied in motion, during the first meters, the car in progress generates an air stream that will help the heat escape from the interior and the temperature is reduced as soon as possible.

What is recommended is that when we win speed, Let’s keep the driver or passenger window open and the opposite. If we keep all the windows at the same time open or only one of them we generate that annoying noise caused by the displacement of the air inside the car.

The air, up or down? It is one of the big doubts. Juan José recommends putting the cold air down, “towards the feet” because “the cold air weighs more and the hot air will tend to climb and go through the windows.”

Indeed, Cold air weighs More so it is interesting to put this system into practice as long as we keep the windows of the car open a few meters. In this way, it will help air the interior.

Of course, then Juan José talks about climbing the cold air to the roof. Although in the video it is not mentioned, this should be done when we have already closed the windows. The idea is that the air that escapes for them is hot and if we have them open and put the air to the ceiling, it will escape part of that cold air. With them closed, the cold air “falls” to being denser and cools before the air conditioning.

Maintenance. Finally, do not forget that all this works as long as we have done adequate maintenance. Before going on a trip, it’s always good take an eye on filters To have them in the best state, which will help us to cool more and breathe a better quality air.

Likewise, if the car cools little, it may be due to problems with the load of air conditioning gas. Similarly, it is important to review it before summer because, if you do not, you can find that All workshops are completely full.
