I remember asking myself this question a month ago when I decided to finally get an air conditioner in Orpington, I was a bit pressed on what a basic cooler system should have, but I got to find out that a basic one should contain three components, a compressor, condenser coil and an evaporator coil.
The evaporator works by using cooling coils to remove heat and humidity from the air by using a special tool called refrigerants.The compressor is a pump that moves the refrigerant between the evaporator and the condenser to cool the inside air.
As the air conditioner works by drawing out the heat in our homes or buildings, and then cooling the interior, the condenser uses heat coils to release the collected heat into the air outside.
These are basically the most fundamental things to know about how ACs work. The rest are usually left to the professionals.
