Air mixing and distribution apparatus and vehicle heating or air-conditioning system

摘要

The invention relates to an air mixing and distribution apparatus (32) and to a vehicle heating or air-conditioning system (10) having an air distribution chamber (30), into which a cold air duct (16) opens with a cold air opening (26) and a warm air duct (20) opens with a warm air opening (28). The warm air opening (28) is formed by the outlet of a heat exchanger (22), the cold and warm air openings (26, 28) lie next to one another and in the same plane (34), and the cold air which flows through the cold air opening (26) and the warm air which flows through the warm air opening (28) flow into the air distribution chamber (30). The air distribution chamber (30) has a mixed air outlet (42) for the windscreen and a mixed air outlet (44) for a front diffuser, the mixed air outlets (42, 44) being spaced apart from one another. The apparatus (32) also includes a first air deflection element (52) and a second air deflection element (56).

主权项

1. An air mixing and distribution apparatus for a vehicle heating or air-conditioning system having an air distribution chamber, into which a cold air duct opens with a cold air opening and a warm air duct opens with a warm air opening,
the warm air opening being formed by the outlet of a heat exchanger, the cold air opening and the warm air opening lying next to one another and in the same plane, and the cold air which flows through the cold air opening and the warm air which flows through the warm air opening flowing into the air distribution chamber substantially in the same main flow direction, the air distribution chamber having a mixed air outlet for the windscreen and a mixed air outlet for a front diffuser, the mixed air outlets being spaced apart from one another, and a first air deflection element being provided within the air distribution chamber, which first air deflection element deflects the warm air flow in the direction of the cold air opening, and a second air deflection element being provided within the air distribution chamber, which second air deflection element deflects the cold air flow in the direction of the warm air opening; wherein a cold air bypass opening is provided which opens into the air distribution chamber and is arranged next to the warm air opening on the side of the warm air opening which faces away from the cold air opening; and wherein a bypass deflection element is provided, the bypass deflection element guiding a bypass cold air flow through the cold air bypass opening to at least one mixed air outlet, the bypass deflection element dividing the bypass cold air flow in the direction of the mixed air outlet for the windscreen and for side diffusers.
