Abstract
The present teachings provide for an airflow sound suppressor, such as for an HVAC assembly, for example. The sound suppressor includes a first end configured to be mounted to a first surface of the HVAC assembly. A second end of the sound suppressor is configured to be mounted to a second surface of the HVAC assembly. An elongated portion extends between the first end and the second end. The elongated portion defines a passageway therethrough that extends an entire length of the sound suppressor.
Claims15
An airflow sound suppressor for a heating, ventilation and air cooling (HVAC) assembly, the airflow sound suppressor comprising:
- a first end of the sound suppressor configured to be mounted to a first surface;
- a second end of the sound suppressor configured to be mounted to a second surface;
- and
- an elongated portion extending between the first end and the second end, the elongated portion defining a passageway therethrough extending an entire length of the sound suppressor;
- wherein
- the first and the second mounting surfaces are selected from a plurality of mounting surfaces at an exterior surface of the HVAC assembly defined by a plurality of weakened portions of the exterior surface.
A sound suppressor for a heating, ventilation, and air cooling (HVAC) assembly comprising:
- a first end of the sound suppressor mounted to the HVAC assembly at a first aperture in a first mounting surface defined by the HVAC assembly;
- a second end of the sound suppressor mounted to the HVAC assembly at a second aperture in a second mounting surface defined by the HVAC assembly spaced apart from the first aperture;
- and
- a flexible elongated portion extending from the first end to the second end, the flexible elongated portion defining a passageway therethrough extending an entire length of the sound suppressor;
- wherein
- the first and the second mounting surfaces are selected from a plurality of mounting surfaces at an exterior surface of the HVAC assembly defined by a plurality of weakened portions of the exterior surface.
A method for suppressing a target sound of an airflow assembly comprising:
- selecting a flexible sound suppressor tube defining an airflow passageway from a plurality of flexible sound suppressor tubes having different dimensions based on location and frequency of the target sound to be suppressed;
- selecting a first mounting location on the airflow assembly for mounting a first end of the flexible sound suppressor tube and selecting a second mounting location on the airflow assembly for mounting a second end of the flexible sound suppressor tube based on the location and frequency of the target sound;
- and
- mounting the first end of the flexible sound suppressor tube to a first aperture of the airflow assembly at the first mounting location and mounting the second end of the flexible sound suppressor tube to a second aperture of the airflow assembly at the second mounting location to permit airflow of the airflow assembly to pass through the airflow passageway and suppress the target sound;
- wherein
- the airflow assembly is a heating, ventilation and air cooling (HVAC) assembly;
- and
- the first and the second mounting locations are selected from a plurality of mounting locations at an exterior surface of the HVAC assembly defined by a plurality of weakened portions of the exterior surface.
