Questions and Answers
What material is recommended for sound attenuation in supply and return plenums?
What should be included in supply duct to reduce air noise?
What should be done if existing ducting is too small?
Study Notes
- Duct system should be sized to handle design airflow quietly
- Flexible connector recommended for duct connections to eliminate vibration transfer
- Supply and return plenums should have fiberglass duct liner or be constructed from ductboard for sound attenuation
- Application to uninsulated ductwork in unconditioned space is not recommended
- At least one 90° elbow should be included in supply duct to reduce air noise
- Blower speed can be changed to address air noise or excessive air flow
- Check existing ductwork capacity before connecting unit
- Larger ductwork should be installed if existing ducting is too small
- Check for leaks and repair existing ductwork
- Variable capacity and air flow duct and register sizing is crucial for proper air delivery and sound levels.
