  • Vehicle air conditioning air duct system
    Patent number: 6625994
    Abstract: If a refrigerant leaks from an interior heat exchanger, an outside air mode is switched ON, and a first bypass channel is opened to supply air, not having passed through the interior heat exchanger, to a passenger compartment through a defroster opening portion, while also supplying air, having passed through the internal heat exchanger, to the passenger compartment through a foot opening portion. Consequently, air having passed through the first bypass channel and thereby containing a considerable quantity of outside air free from the leaked refrigerant is supplied to the upper side of the passenger compartment, while air having passed through the interior heat exchanger and thereby containing the leaked refrigerant is supplied to the lower side of the passenger compartment, which makes it possible to prevent driver inhalation of the refrigerant.
