Sound attenuator for a terminal unit

A heating, ventilation, and air conditioning (HVAC) system, comprising:

• a terminal unit, comprising:
• a housing comprising a plurality of panels, wherein the plurality of panels defines an interior volume of the terminal unit, and wherein the plurality of panels comprises a first panel and a second panel;
• a first blower disposed within the housing and configured to discharge air via a first outlet formed in the first panel of the plurality of panels;
• a second blower disposed within the housing and configured to discharge air via a second outlet formed in the first panel of the plurality of panels;
• a first inlet and a second inlet formed in the second panel of the plurality of panels, wherein the first inlet is configured to direct a first air flow into the interior volume, and the second inlet is configured to direct a second air flow into the interior volume, and wherein the second panel is disposed opposite the first panel relative to the interior volume;
• a baffle coupled to the second panel at the second inlet and extending into the interior volume;
• and
• a sound attenuator coupled to the second panel at the second inlet, wherein the sound attenuator is configured to receive the second air flow and direct the second air flow into the interior volume via the second inlet, and wherein the sound attenuator is translatable relative to the baffle and into the interior volume via the second inlet.

A terminal unit of a heating, ventilation, and air conditioning (HVAC) system, comprising:

• a housing defining a plenum, wherein the housing comprises a panel defining a first inlet configured to direct a first air flow into the plenum and a second inlet configured to direct a second air flow into the plenum;
• a first blower and a second blower disposed within the housing;
• a sound attenuator coupled to the panel and configured to receive the first air flow and direct the first air flow into the plenum via the first inlet;
• a first baffle coupled to the panel on a first side of the first inlet and extending into the plenum;
• and
• a second baffle coupled to the panel on a second side of the first inlet and extending into the plenum, wherein the sound attenuator is translatable relative to the first baffle and the second baffle to slide into the plenum via the first inlet.
