Abstract

The invention relates to a heating, ventilation, and air conditioning (HVAC) system for a motor vehicle, the HVAC system having a length greater than a width and disposed with the length parallel to a longitudinal axis of the motor vehicle between the front seats thereof. The HVAC system includes a blower assembly disposed beneath an instrument panel of the motor vehicle or inside an engine compartment.

Claims

1. An HVAC system for a motor vehicle comprising:

a housing having a first portion disposed in an interior of the motor vehicle and a second portion disposed in an engine compartment of the motor vehicle, the housing having a length greater than a width, the housing disposed with the length substantially parallel to a longitudinal axis of the motor vehicle;

a blower assembly disposed within the second portion of the housing, wherein a wall is disposed between the blower assembly and the interior of the motor vehicle;

a fresh air cowl in fluid communication with the blower assembly, the fresh air cowl providing fluid communication between an exterior of the motor vehicle and the blower assembly to facilitate a flow of fresh air through the HVAC system, the fresh air cowl disposed above the blower assembly;

a conduit providing fluid communication between the fresh air cowl and the blower assembly, the conduit including a first portion through which the fresh air flows in a direction towards a front end of the motor vehicle and a second portion through which the fresh air flows in a direction towards a rear end of the motor vehicle, the second portion of the conduit leading into the blower assembly;

an evaporator disposed in the first portion of the housing downstream of the blower; and

a heater core disposed in the first portion of the housing downstream of the evaporator, wherein the conduit includes a 180 degree bend formed therein between the first portion of the conduit and the second portion of the conduit.

2. The HVAC system of claim 1, wherein the housing is disposed at least partially between front seats of the motor vehicle.

3. The HVAC system of claim 1, further comprising a recirculated air opening formed in the housing providing fluid communication between an interior of the motor vehicle and the blower assembly.

4. The HVAC system of claim 1, wherein the blower assembly is in fluid communication with at least one of:

front seats of the motor vehicle, a rear seat of the motor vehicle, and a steering wheel of the motor vehicle.

5. The HVAC system of claim 1, wherein the housing has a stair-step cross-sectional shape.

11. The HVAC system of claim 1, wherein the blower, the evaporator, and the heater core are substantially aligned in a direction of flow along a horizontal plane.

12. The HVAC system of claim 1, further comprising a supplemental heater disposed in the portion of the housing disposed in the interior of the motor vehicle, the supplemental heater configured to heat a flow of air therethrough.

6. An HVAC system for a motor vehicle comprising:

a housing having a first portion disposed in an interior of the motor vehicle and a second portion disposed in an engine compartment of the motor vehicle, the housing having a length greater than a width, the housing disposed with the length substantially parallel to a longitudinal axis of the motor vehicle and at least partially between front seats of the motor vehicle;

a blower assembly disposed within the second portion of the housing, wherein a wall is disposed between the blower assembly and the interior of the motor vehicle;

a fresh air cowl in fluid communication with the blower assembly, the fresh air cowl providing fluid communication between an exterior of the motor vehicle and the blower assembly to facilitate a flow of fresh air through the HVAC system, the fresh air cowl disposed above the blower assembly;

a conduit providing fluid communication between the fresh air cowl and the blower assembly, the conduit including a first portion through which the fresh air flows in a direction towards a front end of the motor vehicle and a second portion through which the fresh air flows in a direction towards a rear end of the motor vehicle, the second portion of the conduit leading into the blower assembly;

an evaporator disposed in the first portion of the housing downstream of the blower; and

a heater core disposed in the first portion of the housing downstream of the evaporator, wherein the conduit includes a 180 degree bend formed therein between the first portion of the conduit and the second portion of the conduit.

7. The HVAC system of claim 6, further comprising a recirculated air opening formed in the housing providing fluid communication between the interior of the motor vehicle and the blower assembly.

8. The HVAC system of claim 6, wherein the blower assembly is in fluid communication with at least one of:

the front seats of the motor vehicle, a rear seat of the motor vehicle, and a steering wheel of the motor vehicle.

9. The HVAC system of claim 6, wherein the housing has a stair-step cross-sectional shape.

10. An HVAC system for a motor vehicle comprising:

a housing having a first portion disposed in an interior of the motor vehicle and a second portion disposed in an engine compartment of the motor vehicle, the housing having a length greater than a width, the housing disposed with the length substantially parallel to a longitudinal axis of the motor vehicle and at least partially between front seats of the motor vehicle;

a blower assembly in fluid communication with an exterior of the motor vehicle disposed within the second portion of the housing, wherein a wall is disposed between the blower assembly and the interior of the motor vehicle;

a fresh air cowl in fluid communication with the blower assembly, the fresh air cowl providing fluid communication between an exterior of the motor vehicle and the blower assembly to facilitate a flow of fresh air through the HVAC system, the fresh air cowl disposed above the blower assembly;

a conduit providing fluid communication between the fresh air cowl and the blower assembly, the conduit including a first portion through which the fresh air flows in a direction towards a front end of the motor vehicle and a second portion through which the fresh air flows in a direction towards a rear end of the motor vehicle, the second portion of the conduit leading into the blower assembly;

an evaporator disposed in the first portion of the housing downstream of the blower; and

a heater core disposed in the first portion of the housing downstream of the evaporator, wherein the conduit includes a 180 degree bend formed therein between the first portion of the conduit and the second portion of the conduit.
