How does the air conditioning system in our car work?

Model: (Various brands) Various
Part: A/C system

In this video we see a diagram that is valid for most cars, and that tells us how the air conditioning system works. Inside a closed circuit, a pre-charged refrigerant gas flows: the gas reaches the compressor, where it is compressed and its temperature increases, and follows the path of the piping, and reaches the condenser, which turns it from a gaseous state to a liquid state, then it reaches the filter - which removes condensation and impurities - and from there to the expansion valve, which reduces the pressure, and consequently the heat of the fluid; from here we can obtain the temperature that cools the interior of the car.
