Abstract

A heating, ventilation, and air-conditioning (HVAC) conduit includes a first HVAC line at least partially nested within a second HVAC line having a configuration defining a U- or C-shaped receiver in cross-section. The first HVAC line is fabricated of a first material and the second HVAC line is fabricated of a second material that is different from the first material.

First claim

What is claimed:

1. A heating, ventilation, and air-conditioning (HVAC) conduit, comprising a first HVAC line at least partially nested within a second HVAC line having a configuration defining a U- or C-shaped receiver in cross-section;
wherein the first HVAC line is fabricated of a first material and the second HVAC line is fabricated of a second material that is different from the first material.

2. The HVAC conduit of claim 1 , wherein the second HVAC line defines an open receiver configured to engage at least a portion of a length dimension of the first HVAC line therein.

3. The HVAC conduit of claim 2 , wherein the first HVAC line is fabricated of a plastic or polymer.

4. The HVAC conduit of claim 2 , wherein the second HVAC line is fabricated of a metal.

5. The HVAC conduit of claim 4 , wherein the metal is aluminum or an alloy thereof.

6. The HVAC conduit of claim 1 , further including a connector securing the first HVAC line to the second HVAC line.

7. The HVAC conduit of claim 6 , wherein the connector is one or more of a strap, a band, a sheath, a sleeve, and a bracket holding at least a portion of the nested first and second HVAC lines.

8. A vehicle heating, ventilation, and air-conditioning (HVAC) system comprising a plurality of HVAC lines adapted for transport of fluids at a high temperature and/or pressure and a plurality of HVAC lines adapted for transport of fluids at a low temperature and/or pressure, further including one or more HVAC conduits each comprising a first HVAC line at least partially nested within an open receiver defined by a second HVAC line.

9. The HVAC system of claim 8 , wherein the first HVAC line is fabricated of a first material and the second HVAC line is fabricated of a second material having a different resistance to high temperature and/or pressure than the first material.

10. The HVAC system of claim 9 , wherein the first HVAC line is a low pressure HVAC line fabricated of a plastic or polymer.

11. The HVAC system of claim 9 , wherein the second HVAC line is a high pressure HVAC line fabricated of a metal.

12. The HVAC system of claim 9 , wherein the second HVAC line is a low pressure HVAC line fabricated of a plastic or polymer.

13. The HVAC system of claim 8 , wherein the first HVAC line is a high pressure HVAC line fabricated of a metal.

14. A vehicle heating, ventilation, and air-conditioning (HVAC) system, comprising:
a high pressure side;
a low pressure side;
a plurality of HVAC lines adapted for transporting high pressure fluids and low pressure fluids through and between the high pressure side and the low pressure side; and
one or more HVAC conduits comprising a plastic or polymer low pressure HVAC line at least partially nested with a metal high pressure HVAC line.

15. The HVAC system of claim 14 , wherein the metal high pressure HVAC line defines an open receiver configured to engage at least a portion of a length dimension of the plastic low pressure HVAC line therein.

16. The HVAC system of claim 14 , wherein the plastic or polymer low pressure HVAC line defines an open receiver configured to engage at least a portion of a length dimension of the metal high pressure HVAC line therein.

17. The HVAC system of claim 14 , wherein the metal is aluminum or an alloy thereof.

18. The HVAC system of claim 14 , further including a connector securing the plastic low pressure HVAC line to the metal high pressure HVAC line.

19. The HVAC system of claim 18 , wherein the connector is one or more of a strap, a band, a sheath, a sleeve, and a bracket holding at least a portion of the plastic low pressure and metal high pressure HVAC lines.
