摘要： A plenum with features to disperse acoustic energy in an airflow while maintaining a relatively small pressure drop in the airflow is disclosed. A general structure of the plenum may include a perforated airflow passage surrounded by a substantially large space enclosed between the airflow passage and a plenum. The perforated airflow passage has a perforated wall that may allow the acoustic energy to be dispersed into the substantially large space when flowing through the airflow passage. Acoustic energy dispersing materials may also be disposed in the substantially large space and/or on the perforated wall to help disperse acoustic energy by, for example, absorbing the acoustic energy. The plenum can help disperse the acoustic energy while helping minimize the pressure drop in the airflow.

摘要： A system and method for controlling the operation of heating, ventilating, and air conditioning (HVAC) equipment so as to achieve a desired range of a sound pressure level and/or a sound power level is described. The system and method can lead to a desired range of a sound pressure level and/or a sound power level for a zone using equipment that is typically included in HVAC systems. Such control of equipment can be important for privacy and comfort requirements.

摘要： Methods and apparatus to reduce instabilities and/or turbulence of an airflow of a HVAC system are described. The method may include positioning an airflow moderating zone in an airflow passage to reduce instabilities and/or turbulence in the airflow. Apparatuses to create the airflow moderating zone are also provided. The apparatus may be configured to have a plurality of openings and an airflow resistance structure so as to provide airflow resistance to instabilities and/or turbulence in the airflow. The airflow moderating zone may be, for example, a sheet-like material including a plurality of openings.
