Abstract
A filter bank is provided. The filter bank includes a housing having a front face and a back face. Air flows along an air flow path from the front face to the back face. A filter layer is held in the housing. The filter layer is oriented between the front and back faces such that air flows through the filter layer before discharging from the back face. An attenuation layer is positioned within the housing to attenuate sound as the sound propagates between the front and back faces. The attenuation layer is oriented to extend along the air flow direction.
Claims41
A filter bank, comprising:
- a housing having walls extending between a front face and a back face, an air channel formed between the walls, wherein air flows through the air channel along an air flow path from the front face to the back face;
- a filtering layer held in the air channel of the housing, the filtering layer oriented between the front and back faces such that air flows through the filtering layer before discharging from the back face;
- and
- an attenuating layer positioned within the air channel between the walls of the housing to attenuate sound as the sound propagates between the front and back faces, the attenuating layer oriented to extend along the air flow direction.
An air handling unit comprising:
- a fan for drawing an air flow path through the air handling unit;
- and
- a filter bank for filtering the air flow path, the filter bank comprising:
- a housing having walls extending between a front face and a back face, an air channel formed between the walls, wherein air flows along the air flow path through the air channel from the front face to the back face;
- a filtering layer held in the air channel of the housing, the filtering layer oriented between the front and back faces such that air flows through the filtering layer before discharging from the back face;
- and
- an attenuating layer positioned within the air channel between the walls of the housing to attenuate sound as the sound propagates between the front and back faces, the attenuating layer oriented to extend along the air flow direction.
A method of filtering and attenuating sound within an air handling unit, said method comprising:
- positioning a housing having walls extending between a front face and a back face within the air handling unit, the walls defining an air channel through at least a portion of the air handling unit, wherein air flows along an air flow path from the front face to the back face;
- coupling a filtering layer within the air channel of the housing, the filtering layer oriented between the front and back faces such that air flows through the filtering layer before discharging from the back face;
- and
- positioning an attenuating layer within the air channel between the walls of the housing to attenuate sound as the sound propagates between the front and back faces, the attenuating layer oriented to extend along the air flow direction.
