Interchangeable HVAC ducts
A portable heating, ventilation, and air conditioning (HVAC) unit includes a housing, a plate, and a duct assembly. The housing defines a first airflow exit and a second airflow exit. The first airflow exit is separated from the second airflow exit by a portion of the housing. The plate is configured to cover the first airflow exit. The duct assembly is configured to cover the second airflow exit. The plate is configured to be disassembled from the housing and reassembled to cover the second airflow exit, and the duct assembly is configured to be disassembled from the housing and reassembled to cover the first airflow exit.
1. A portable heating, ventilation, and air conditioning (HVAC) unit comprising:
a housing defining a first airflow exit and a second airflow exit, the first airflow exit being separated from the second airflow exit by a portion of the housing;
a vent cover configured to cover the first airflow exit; and
a duct assembly configured to cover the second airflow exit;
wherein the vent cover is configured to be disassembled from the housing and reassembled to cover the second airflow exit, the duct assembly is configured to be disassembled from the housing and reassembled to cover the first airflow exit, and the vent cover includes a top plate and a first fin, the first fin extending from the top plate.
2. The HVAC unit of claim 1 , wherein the first fin extends orthogonal to the top plate.
3. The HVAC unit of claim 1 , wherein the first fin is configured to direct an airflow through the housing.
4. The HVAC unit of claim 1 , wherein the duct assembly includes at least two ducts.
5. The HVAC unit of claim 4 , wherein the first fin is one of at least one fin, and a number of fins in the at least one fin is one less than a number of ducts in the at least two ducts.
6. The HVAC unit of claim 1 , wherein the top plate is fixed to the housing by a plurality of removable fasteners.
7. The HVAC unit of claim 1 , wherein the vent cover includes a wedge disposed between the top plate and the first fin.
8. The HVAC unit of claim 7 , wherein the wedge includes an angle within a range of about 30° to about 60°.
9. The HVAC unit of claim 1 , wherein the duct assembly includes a duct plate, the duct plate having a same size and perimeter shape as a size and perimeter shape of the top plate.
10. The HVAC unit of claim 1 , wherein the duct assembly includes a duct plate and a duct, the duct aligning with an aperture defined by the duct plate.
11. The HVAC unit of claim 10 , wherein the duct is fixed to the duct assembly by a fastening ring.
12. The HVAC unit of claim 10 , wherein the duct plate is fixed to the housing by a plurality of removable fasteners.
13. The HVAC unit of claim 1 , wherein the vent cover is fixed to the housing by a plurality of removable fasteners.
14. The HVAC unit of claim 1 , wherein the duct assembly is fixed to the housing by a plurality of removable fasteners.
15. A duct assembly for a heating, ventilation, and air conditioning (HVAC) unit, the HVAC unit comprising: a housing defining a first airflow exit and a second airflow exit, the first airflow exit being separated from the second airflow exit by a portion of the housing; a vent cover configured to cover the first airflow exit; and a duct assembly configured to cover the second airflow exit; wherein the vent cover is configured to be disassembled from the housing and reassembled to cover the second airflow exit, the duct assembly is configured to be disassembled from the housing and reassembled to cover the first airflow exit, and the vent cover includes a top plate and a first fin, the first fin extending from the top plate;
the duct assembly comprising: a plate defining an aperture; and a duct fixed to the plate and aligning with the aperture; and a fastening ring configured to fasten the duct to the plate; wherein the plate includes a plurality of fastening apertures, each of the plurality of fastening apertures being configured to receive a removable fastener for fastening the plate to the housing of the HVAC unit; and wherein the plate includes a protrusion around a perimeter of the aperture, a first end of the duct being slideably received over the protrusion, and the fastening ring being configured to tighten the first end of the duct on the protrusion and fix the duct to the plate.
16. The duct assembly of claim 15 , further comprising an end ring configured to cover a free end of the duct.
17. The duct assembly of claim 15 , wherein the plate is sized to cover at least two airflow exits in the housing of the HVAC unit, the plate covering one of the at least two airflow exits at a time.
18. The duct assembly of claim 15 , wherein the duct is one of two ducts fixed to the plate.
