it is named by its number and a letter indicating which series it is for that number.
There is no such thing as Air Conditioning coolant.
Yes, air conditioning units pull in air from outside, cool it, and then circulate it to cool the indoor space.
No.
An "air conditioning" system.
Yes, central air conditioning systems typically pull air from inside the building, cool it, and then circulate it back into the indoor space.
It strains any impurities from the coolant.
If the coolant in an air conditioner has a lower temperature than the surrounding air, it absorbs heat from the air, leading to a cooling effect. This process occurs as the coolant evaporates, transitioning from a liquid to a gas, thereby removing heat from the indoor environment. The cooled air is then circulated back into the space, lowering the overall temperature. This heat exchange is fundamental to the operation of air conditioning systems.
Air conditioning involves the transformation of electrical energy into thermal energy. The electrical energy is used to power the air conditioning unit, which then removes heat from the indoor air, cooling it down.
Your description sounds like engine coolant to me.

Originally this car had R12 refrigerant. It may have since been updated to accept R134a. The coolant/radiator system is not part of the air conditioning system. But the hot antifreeze-coolant is used for the heating system...
