At the expansion valve or fixed orifice tube depending on the system liquid refrigerant quickly expands into a gas forcing the temperature to drop. The problem of car ac lines freezing up is caused by moisture that has been introduced into the system. This causes the evaporator to. If low air flow caused it the evaporator would freeze up every time you turned the blower speed down.
