  • Publication number: 20200079174
    Abstract: An air-conditioning system for a motor vehicle includes an evaporator, a heating device arranged downstream of the evaporator, an evaporator bypass duct arranged below the evaporator, and at least one air guiding duct. The at least one air guiding duct has an inlet end that is communicatingly connected to the evaporator bypass duct and an outlet side that opens or ends between the evaporator and the heating device. The at least one air guiding duct is structured and arranged such that outside air flowing through the evaporator bypass duct and the air guiding duct(s) enters the heating device. The at least one air guiding duct includes a lateral collar extending outwardly therefrom, structured and arranged to facilitate discharging condensate from the evaporator into a condensate pan.
