Abstract
A system for mixing air for a vehicle HVAC (heating, ventilation, air-conditioning) component, includes a first inlet for outdoor air from an exterior space of the vehicle; a first fan in communication with the first inlet to control (only) an air inflow through the first inlet; a second inlet for indoor air from an interior space of the vehicle; and a second fan in communication with the second inlet to control (only) an air inflow through the second inlet. The first fan and the second fan are independently controllable to provide a desired mix of air to the vehicle HVAC component.
Claims11
A system for mixing air for a vehicle heating, ventilation, air-conditioning (HVAC) component, the system comprising:
- a first inlet for outdoor air from an exterior space of the vehicle;
- a first fan in communication with the first inlet to control only an air inflow through the first inlet;
- a second inlet for indoor air from an interior space of the vehicle;
- a second fan in communication with the second inlet to control an air inflow through the second inlet, wherein the first fan and the second fan have a fixed aperture;
- vehicle HVAC components, wherein the components include two heat exchangers,
- a control unit configured to independently control the first fan and the second fan to provide a desired mix of air to the vehicle HVAC components;
- a housing for accommodating at least the first fan, the second fan, and the HVAC component;
- a mixing zone arranged inside the housing downstream of the first fan and the second fan and upstream and between the HVAC components, the mixing zone configured to mix the air from the first fan and the second fan;
- and
- two supply openings for supplying an output of the HVAC components to a vehicle compartment, each of the two supply openings in communication with one of the two heat exchangers and connected to one or more vehicle compartments,
- wherein the first fan and the second fan are located between the two heat exchangers.
A method for mixing air for a vehicle heating, ventilation, air-conditioning (HVAC) components, the method comprising:
- providing outdoor air from an exterior space of the vehicle through a first inlet by controlling a first fan;
- providing indoor air from an interior space of the vehicle through a second inlet by controlling a second fan;
- wherein the first fan and the second fan have a fixed aperture;
- controlling the first fan and the second fan to provide downstream of the first fan a desired mix of air to the vehicle HVAC components in a mixing zone arranged inside a housing downstream of the first fan and the second fan and upstream and between the HVAC components, the mixing zone configured to mix the air from the first fan and the second fan, wherein the components include two heat exchangers;
- and
- supplying an output of the HVAC components via two supply openings to a vehicle compartment, each of the two supply openings in communication with one of the two heat exchangers and connected to one or more vehicle compartments, wherein the first fan and the second fan are located between the two heat exchangers.
