Abstract: A centrifugal blower unit for motor vehicle air conditioning systems having a fan wheel (8) in a spiral housing (1), wherein the spiral housing (1) corresponds to the shape of the fan wheel (8) and has a bell mouth region (3) and an axial intake opening (2), wherein a diaphragm (4) is arranged at the bell mouth region (3) of the spiral housing (1), being radially inward, whose diaphragm end region (5) bordering the intake opening (2) has at least one sharp edge.

Abstract: A control damper for a housing of an air-handling unit includes a rigid main body rotatable about a first rotational axis. A sealing element extends radially outwardly from a first side of the rigid main body. The sealing element is formed of a resilient material. The sealing element further includes a resilient lip extending outwardly from a distal end thereof. The lip has a first series of undulations formed in an outer edge thereof, wherein the undulations form a wave-shaped profile in the outer edge of the lip.

Abstract: A control module for a heating, ventilating, and air conditioning system for a vehicle is disclosed, wherein a cost and a space requirement for the system are minimized and a control of temperature, mode, and volume of an air flow in a passenger compartment of the vehicle is optimized.

Abstract: Pairs of corresponding connecting elements for connecting two components at a predefined joining direction by a catch connection fixedly attached to the components to be joined, such that one of the connecting elements has a structure suitable for engaging behind the catch face and the catch face behind which the structure is to engage is situated on the other element of the corresponding connecting elements. At least one of the two connecting elements has a ramp-shaped structure with which the respective other connecting element is in contact during the joining movement and which ensures an elastic deformation as the deflection in preparation for the locking engagement of at least one of the connecting elements during the joining movement, such that the catch face behind which the structure is to engage is situated behind the ramp-shaped structure in the joining direction.

Abstract: The present invention involves a compact vehicle temperature control system. The system includes a housing, an evaporator core and a heater core disposed in the housing, and a separation wall disposed between the evaporator core and heater core. The housing has an intake opening for air intake and an output opening for output air. The evaporator core is in fluid communication with the intake opening. The heater core is disposed downstream from the evaporator core and in fluid communication with the evaporator core, defining a space between the evaporator core and the heater core. The heater core has a first portion and a second portion. The separation wall has a first end and a second end. The first end is attached to the first portion of the heater core and extends therefrom along the length of the heater core in the space between the evaporator core and the heater core.
