Located at the evaporator of the air conditioner, this conversion is facilitated by passing the coolant through it making sure that it cools thus cooling down the air flow being delivered into vents. Typically, such a change is brought about by a sudden variation in tube sizes; however some vehicles may have a removable controlled orifice within one of their firewalls connected to a certain refrigerant line. Nonetheless, an automatic expansion valve which performs the same function as a controlled orifice.
