Embodiment Construction

[0021] The following description is merely exemplary in nature and not intended to limit the present disclosure, application and use. It should be understood that throughout the drawings, corresponding reference numerals indicate similar or corresponding parts and features.

[0022] first reference figure 1 , a vehicle 10 is shown. Vehicle 10 includes an engine compartment, shown generally at 12 . The vehicle 10 also includes a cabin 14 . A heating, ventilation and air conditioning (HVAC) unit 16 is contained in the figure 1 In the compartment 14 shown schematically in . The cabin 14 defines an interior space 18 within the cabin 14 and an exterior space 20 outside the cabin 14 . The HVAC unit 16 heats and / or cools the air in the interior space 18 of the vehicle cabin 14 in a known manner.

[0023] now refer to figure 2 , 3 and 4 , show the blower unit 30 of the HVAC unit 16 . Generally, the blower unit 30 draws in air from the interior space 18 and / or the exterior sp...

Abstract

A heating, ventilation and air conditioning system comprising a blower unit (30) having a first internal air intake (40a), a second internal air intake (40b) and an external air intake (38). Three doors (70, 72, 74) move between open and closed positions to define a recirculation mode, a fresh mode and a partial recirculation mode. As the doors (70, 72, 74) move between their open and closed positions, variable partial modes and variable fresh modes are defined.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Utility Application No. 14 / 011,895, filed August 28, 2013, and US Provisional Application No. 61 / 694,946, filed August 30, 2012. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure relates to a vehicle heating, ventilation and air conditioning (HVAC) system. More specifically, the present disclosure relates to a three-door configuration for local recirculation in HVAC systems. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Vehicles are known to incorporate HVAC systems to enhance the comfort of occupants in the vehicle cabin. The HVAC system heats and cools air blown through the HVAC system using a heating type heat exchanger and / or a cooling type heat exchanger. Heating-type heat exchange ...
