The invention relates to a heating, ventilation and/or air-conditioning unit (10) for a motor vehicle, comprising a first air guide (22) for guiding a first air flow as a cold air flow and a second air guide (24) for guiding a second air flow, separate from the first air flow, as a warm air flow, a heating device (26) for heating the second air flow is arranged in the second air guide (24). The heating, ventilation and/or air conditioning unit (10) also has a first mixing chamber (28) and a second mixing chamber (30), wherein the first mixing chamber (28) and the second air guide (24) each have at least one inlet opening (32, 34) to the second mixing chamber (30). In the second air guide (24), a baffle (44) is arranged which can be moved between a closed position, in which a flow path of the second air flow to the first mixing chamber (28) is closed, and an open position, in which the second air flow can flow into the first mixing chamber (30), a baffle (44) is arranged downstream of the heating device (26) and at an inlet opening (27) of the second air guide (24) into the first mixing chamber (28).
提出了一种用于汽车的加热、通风和/或空调单元(10),其具有用于引导作为冷空气流的第一空气流的第一空气引导部(22)和用于引导与第一空气流分开的作为暖空气流的第二空气流的第二空气引导部(24),其中,用于加热第二空气流的加热装置(26)布置在第二空气引导部(24)中。加热、通风和/或空调单元(10)还具有第一混合室(28)和第二混合室(30),其中第一混合室(28)和第二空气引导部(24)分别具有至少一个通向第二混合室(30)的入口开口(32、34)。在第二空气引导部(24)中,布置有挡板(44),该挡板可在关闭位置和打开位置之间移动,在关闭位置,第二空气流到第一混合室(28)的流动路径被关闭,在打开位置,第二空气流可流入第一混合室(30),其中,挡板(44)布置在加热装置(26)的下游并且在第二空气引导部(24)进入第一混合室(28)的入口开口(27)处。
