Air conditioning not only cools it, but it also reduces humidity, and all air conditioners work in the same way whether they are installed in a building or in a car, or the refrigerator or freezer in some way the air conditioner as well.
The importance of changing the conditioner
- When the car air conditioner fails, its parts must be carefully examined to know the exact location of the defect, and one of the most important parts that must be looked at is the air conditioner, so care must be taken to keep it clean and change it constantly, and the chips contribute to maintaining the integrity of the compressor, because the clutch compressor It consumes 12 volts other than the 6-volt electrode, and it must be checked that the electricity is good.
Air conditioning parts
- A number of people don't realize that operating an air conditioner actually reduces the mileage per gallon of your car. There is the energy used to remove heat and moisture from the air in the car, and this consumes gasoline due to the engine overload. The main principles of air conditioning are evaporation and condensation, then pressure and expansion, as follows:
Evaporation
You may have noticed that if you rub some surgical spirits on the back of your hand, your hand will feel cold, and it takes heat from the surface of your skin.
Condensation
Humid air cools while in contact with the cold surface, and the air is less able to retain moisture, so it condenses in water.
Heat of compression
Have you ever noticed that when you pump a bicycle tire with a hand pump, the pump end gets hot? This is because the energy you put into the air by pumping it not only pressed it but also brought the air molecules together, causing the heat to cool down using friction.
Compression
- At some point all the gases become liquid at the end, an example of this could be a deodorant box - it's a liquid inside the can (because you can hear it when disposing of it) but it is a gas when it comes out and hits the armpit since the pressure inside the can is higher, so the substance The drive inside is liquid.
Cooling by expansion
- Returning to deodorant, you'll also notice how cold you feel because the impulse has rapidly expanded in size.
Expansion valve
- The compressed coolant flows from the receiver dryer to the expansion valve, and the valve removes pressure from the coolant so that it can expand and become the coolant vapor in the evaporator.
the future
The coolant now travels to the receiver, and this is a small container for the liquid cooler tank, removes any moisture that has leaked into the coolant, and the moisture in the system causes chaos, as the ice crystals cause mechanical blockage and damage.
How air conditioning works
Hard tubes and flexible hoses connect all the actual components of your car's air conditioning, evaporation, condensation, expansion, and pressure are the physics of its success. There are five main components of the entire system, which are the compressor, condenser, reception dryer, expansion valve, and evaporator.
- The fluid that passes around the entire system is a coolant, and the coolant can evaporate at a low temperature, then condense again at a higher pressure, and in the old days, R-12 was the refrigerants used in almost all cars, and was available on a range It was wide, but it turned out that it was a contributor to the hole in the ozone layer on the ground as it was CFCs, and these refrigerants were stopped, and all cars became used after 1996 AD a non-liquid fluid CFC called R-134A, which is a type of The environment.
The whole process is reasonably simple when clarified like this, and all air conditioning systems work on the same principle, even if the exact components used differ slightly between car manufacturers, and we hope to explain a little how the little "A / C" button works on Your car if you want to explain it a little more deeply.
