Most people think the air conditioning system's job is to add “cold” air to the interior of the car. Actually, there is no such thing as “cold”, just an absence of heat, or less heat than our bodies are comfortable with.

Air conditioning, or cooling, is really a process of removing heat from an object (like air).
