Longitudinally split fabric air duct

An air duct assembly for connection to a vertically extending inlet duct, the air duct assembly comprising:

• a pliable tube attached to the vertically extending inlet duct;
• an upper sheet made of a first pliable material, the upper sheet defining an inlet opening with a first separable joint extending along a perimeter of the inlet opening for connecting the upper sheet to the pliable tube;
• a lower sheet made of a second pliable material;
• the first separable joint connecting the upper sheet to the pliable tube, thereby placing the vertically extending inlet duct in fluid communication with the inlet opening of the upper sheet;
• a second separable joint coupling the upper sheet adjacent the lower sheet, the second separable joint comprising a track defining:
• a first opening through which a first portion of the upper sheet extends;
• and
• a second opening spaced-apart from the first opening and through which a first portion of the lower sheet extends;
• and
• a third separable joint coupling the upper sheet adjacent the lower sheet, wherein the second separable joint and the third separable joint are spaced-apart from each other with the upper sheet and the lower sheet extending therebetween, the second and third separable joints each connected with a support to orient the respective separable joint at a predetermined position for coupling the upper and lower sheets, and the upper sheet, the lower sheet, and the separable joints defining an enclosed horizontally extending air passageway therebetween.

A method of installing an air duct assembly to a vertically extending inlet duct, wherein the air duct assembly includes a pliable tube, an upper sheet made of a first pliable material and a lower sheet made of a second pliable material, the upper sheet defining an inlet opening, the method comprising:

• coupling the pliable tube to the vertically extending inlet duct;
• coupling the upper sheet to the pliable tube via a separable joint extending along a perimeter of the pliable tube, thereby placing the vertically extending inlet duct in fluid communication with the inlet opening;
• supporting a track relative to a structure to orient the track at a predetermined position, the track having a first channel and a second channel;
• coupling a first edge of the lower sheet at the first channel of the track;
• coupling a first edge of the upper sheet at the second channel of the track;
• and
• coupling a second edge of the lower sheet at a second edge of the upper sheet to create an enclosed horizontally elongate air passageway, wherein the first edge of the lower sheet at the first channel of the track is spaced-apart from the first edge of the upper sheet at the second channel of the track.
