| 摘要 |
The invention relates to a climate control device for temperature regulation of passenger compartments in motor vehicles. The device comprises an air treatment chamber (2) through which incoming air to the passenger compartment is made to flow via channels from air intake (4) to air outlet (5) to be temperature-regulated depending upon a nominal value and an actual value for the air temperature in the passenger compartment. The actual value is detected using at least one temperature sensor (12) located in the passenger compartment, and an air stream is created at the sensor by means of a suction duct which is connected to a suction inlet (19) of an ejector (16). The ejector is transversed by streaming air via a pressure inlet (27) and outlet (33) in the air treatment chamber. The ejector (16) has a substantially funnel-shaped jacket (34) widening around the outlet and is located in the air treatment chamber (2) or connecting channels so that its pressure inlet (27) and funnel-shaped jacket is transversed by streaming air in a direction away from the pressure inlet. The air is flowing partly through the outlet and partly surrounding the funnel-shaped jacket. |
