Car air conditioner - how to use?

Proper use of a car's air conditioner is vital to the health of passengers. How to use the air conditioner so as not to harm yourself?

To be able to fully enjoy the benefits of car air conditioning and not put yourself in trouble related to colds or joints, strictly follow the rules for using the air conditioner in the car.

How does the air conditioner work?

The same as the refrigerator in our house. The compressor, located in the engine compartment, increases the pressure of the working fluid, which also increases its temperature. Therefore, it is aimed at the radiator, which we can see by looking into the "grille". After passing through the cooler, the liquefied gas enters the dryer and then to the expansion valve. According to the laws of physics, the expansion of the gas is accompanied by a drop in temperature, due to which the evaporator becomes wintery, and the air passing through it, directed to the car interior, provides us with thermal comfort.

How to use the car air conditioner - before getting into the car

It's easiest to go wrong on hot days, especially when we park our car in the sun. Getting behind the wheel of a car whose interior is warmed up to 50-60 degrees Celsius is not an easy task. Therefore, many drivers decide in such a situation to cool the interior dramatically by turning on the air conditioner and waiting outside the car.

When heated people enter very cold rooms, they develop heat shock, and this is the shortest way to contract a serious infection.

Therefore, in a situation where it is very hot inside the car, it should be well ventilated, and then gradually reduce the interior temperature using the so-called Klima.

How to use the car air conditioner - the optimal temperature for the driver

The optimum temperature for the driver is between 19-21 degrees Celsius. As mentioned above, the cabin should not cool down too quickly. Therefore, when we move around the city, doing business, and getting out of the car every now and then, we must set a higher temperature so that the amplitude between the temperature inside and outside the vehicle is relatively small.

An important aspect when using the air conditioner is also the gradual warming up of the car interior before leaving the car. In fact, the process of equalizing the temperature with the temperature outside the vehicle should begin approximately 20 minutes before the stop. In this way, as in the case of getting into a car, we minimize the phenomenon of thermal shock.

How to use a car air conditioner - the direction of the deflectors

When using an air conditioner, it is important to be careful not only with the temperature potentiometer, but also with the direction and strength of the air flow. It is absolutely unacceptable for health reasons to direct a stream of cool air directly to any part of the body. Setting the airflow on yourself - on your face, feet, hands or neck - is the shortest way to catch very painful inflammation of the muscles and joints. Therefore, it is best to direct the air towards the roof lining and windows of the car.

Another problem associated with the operation of the air conditioner is its pollution. The basis is the regular replacement of the cabin filter. In addition, it is worth checking the air conditioning system at a good service station every two to three years. The service should include changing the refrigerant in the system and cleaning the ventilation system along with the evaporator. In older vehicles that have not been regularly inspected, it is sometimes necessary to disassemble the evaporator to clean it. If the system is not cleaned regularly, fungi can develop in it, leading to allergic reactions and even fungal pneumonia.

The most common air conditioner malfunctions occur due to rotting and leaking of the radiator, which is located first in the engine compartment. It is she who absorbs the most insects, stones, salt and all other pollutants. Unfortunately, most often it is not even varnished, which causes its accelerated wear. As a result of leaks, refrigerant leaks from the system and the performance of the air conditioner drops to a level at which the compressor does not turn on. The most common mistake in this situation is to prime the system and believe it will help. Unfortunately, this helps for a very short time. Therefore, always in the event of a failure of the air conditioning system, you should start by checking the tightness of the system.

The air conditioner, like many other inventions, is designed for people and, when used in moderation, will give us a lot of joy and increase the comfort and safety of travel.
