A heating, ventilation and/or air conditioning unit () for a car is specified, having a first air guide () for guiding a first, cold air stream and having a second air guide () for guiding a second, warm air stream which is separate from the first air stream, wherein a heating device () for warming the second air stream is arranged in the second air guide (). The heating, ventilation and/or air conditioning unit () furthermore has a first mixing chamber () and a second mixing chamber (), wherein the first mixing chamber () and the second air guide () each have at least one inlet opening () to the second mixing chamber (). In the second air guide (), there is arranged a flap () which is movable between a closed position, in which a flow path of the second air stream to the first mixing chamber () is closed, and an open position, in which the second air stream can flow into the first mixing chamber (), wherein the flap () is arranged downstream of the heating device () and at an inlet opening () of the second air guide () into the first mixing chamber ().

Heating, ventilation and/or air conditioning unit for a car

A blower assembly for a vehicle air conditioning unit includes a first air flow duct having a first blower and a second air flow duct having a second blower. A fresh-air inlet opening is arranged in the first air flow duct and a recirculated-air inlet opening is arranged in the second air flow duct. A distribution chamber is downstream of the first and second air flow ducts and an air cooling unit and a bypass duct bypassing the air cooling unit are downstream of the distribution chamber. A bypass flap is in the distribution chamber for directing at least a part of the air flow in the first air flow duct to the air cooling unit and/or to the bypass duct with substantially all of the air flow in the first air flow duct directed into the bypass duct in one position of the bypass flap.

Blower assembly for a vehicle air conditioning unit and method for operating a vehicle air conditioning unit

The invention relates to a vehicle air conditioner (), with an evaporator () for supplying cold air () which can be fed to a vehicle interior (), an air-mixing region () which is connected downstream of the evaporator () and can supply mixed air at a predeterminable temperature, a first ventilation duct () which is connected to the air-mixing region () and can conduct mixed air from the air-mixing region () into a front region () of the vehicle interior (), and a second ventilation duct () which is connected to the air-mixing region () and can conduct mixed air from the air-mixing region () into a rear region () of the vehicle interior (), wherein, in addition, a separate cold air duct (), which can feed cold air (), which is supplied by the evaporator (), to the vehicle interior () in substantially unmixed form is provided.
