Why does the AC blow cold air when the car is moving?

My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation.

Your A/C works by compressing freon, cooling it down since it’s gotten hot from being compressed (through the heat exchanger in front of your car), sent to an expansion tube or valve which causes it to cool down (since decrease in pressure means a decrease in temperature) and into another heat exchanger in your car. This cycle repeats.
