Ram air induction does not exist in normal vehicles for all intents and purposes. Ram air induction is the forced induction of flow due to air flow being compressed (pressurized) into an inlet from the conversion of kinetic energy (velocity). Air is considered incompressible below speeds of about Mach 0.3 or 230 mph.
Return Plenum. Forced-air systems also have return ducts that connect to the HVAC equipment through an air-collection box known as a return plenum. As freshly conditioned air is blown out of the room supply ducts, âusedâ air from the rooms is sucked into the return ducts.he ductwork that distributes the heated or cooled air to individual rooms of the house connects to the plenum. The HVAC equipment has a blower that forces heated or cooled air into the supply plenum and from the plenum into the rooms through the supply duct system.
