Abstract
An environmental conditioning equipment having a chamber, and method of directing fluid through the chamber, includes a chamber, a plenum and an air-moving apparatus for directing air into said chamber via the plenum, and a duct. The duct is formed from a base wall and opposed side walls forming two sides of the duct. Each of the side walls has a plurality air flow openings configured to direct fluid outwardly from the sides of said duct and form air flow areas that decrease is size along the longitudinal axis of the duct.
Claims23
An environmental conditioning equipment comprising:
- a chamber having an upper wall forming a ceiling of the chamber, two opposed side walls, two opposed end walls, and a lower wall forming a floor of said chamber;
- a plenum and an air-moving apparatus for directing air into said chamber;
- and
- a duct having a proximal end, a distal end, and a longitudinal axis extending between said proximal end to said distal end and being mounted at said upper wall of said chamber, said duct being in fluid communication with said plenum at said proximal end, said duct having sides and being formed from a base wall and opposed side walls forming said sides and an exterior of said duct, said base wall and said opposed side walls forming a cross-section defining an air flow area of said duct, said base wall having a length extending along said longitudinal axis and facing and being parallel to said floor of said chamber, said opposed side walls being angled with respect to said base wall, and said base wall being free of air flow openings;
- and
- each of said opposed side walls having a plurality air flow openings configured to direct fluid outwardly from said opposed side walls of said duct, and said cross-section and said air flow area of said duct decreasing along said longitudinal axis wherein the exterior of the duct tapers from its proximal end to its distal end.
An environmental conditioning equipment comprising:
- a chamber having an upper wall forming a ceiling of the chamber, two opposed side walls, two opposed end walls, and a lower wall forming a floor of said chamber;
- a plenum and an air-moving apparatus for directing air into said chamber;
- and
- a duct having a proximal end, a distal end, and a longitudinal axis extending between said proximal end to said distal end and being mounted at said upper wall of said chamber, said duct being in fluid communication with said plenum at said proximal end, said duct having sides and being formed from a base wall and opposed side walls forming said sides of said duct, said base wall being free of air flow openings, and each of said side walls having a plurality air flow openings configured to direct fluid outwardly from said sides of said duct and forming an air flow area that decreases along said longitudinal axis, wherein each of said side walls extends along a respective longitudinal axis, and said respective longitudinal axes converging toward said distal end of said duct wherein said duct is tapered inwardly from said proximal end to said distal end.
An environmental conditioning equipment comprising:
- a chamber having an upper wall forming a ceiling of the chamber, two opposed side walls, two opposed end walls, and a lower wall forming a floor of said chamber;
- a plenum and an air-moving apparatus for directing air into said chamber;
- and
- a duct having a proximal end, a distal end, and a longitudinal axis extending between said proximal end to said distal end and being mounted at said upper wall of said chamber, said duct being in fluid communication with said plenum at said proximal end, said duct having sides and being formed from a base wall and opposed side walls forming said sides of said duct, said base wall being free of air flow openings, and each of said side walls having a plurality air flow openings configured to direct fluid outwardly from said sides of said duct and forming an air flow area that decreases along said longitudinal axis, wherein said side walls form inner obtuse angles with respect to said base wall wherein said duct has a trapezoidal cross-section and said air flow openings are angled downwardly toward said floor.
An environmental conditioning equipment comprising:
- a chamber having an upper wall forming a ceiling of the chamber, two opposed side walls, two opposed end walls, and a lower wall forming a floor of said chamber;
- a plenum and an air-moving apparatus for directing air into said chamber;
- and
- a duct having a proximal end, a distal end, and a longitudinal axis extending between said proximal end to said distal end and being mounted at said upper wall of said chamber, said duct being in fluid communication with said plenum at said proximal end, said duct having sides and being formed from a base wall and opposed side walls forming said sides of said duct, said base wall being free of air flow openings, and each of said side walls having a plurality air flow openings configured to direct fluid outwardly from said sides of said duct and forming an air flow area that decreases along said longitudinal axis, wherein said duct includes a plurality of transverse members extending between said opposed side walls, said transverse members each having an angled surface facing said proximate end of said duct to help direct the flow of air toward said base wall in said duct.
A method of directing air though a chamber of environmental conditioning equipment to improve temperature distribution in the chamber, the environmental conditioning equipment having a plenum and an air-moving apparatus for directing air into the chamber, the chamber having an upper wall forming a ceiling and a lower wall forming a floor of said chamber, said method comprising;
- providing a duct in the chamber at the upper wall of the chamber;
- forming the duct with two opposed sides and a bottom wall forming a cross-section of the duct, the bottom wall for facing and being parallel to the floor of the chamber and being free of air flow openings, and the opposed side walls being angled with respect to the base wall and forming an exterior of the duct, the duct having a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end, and the cross-section of the duct decreasing from the proximal end to the distal end wherein the exterior of the duct tapers from its proximal end to its distal end;
- providing a plurality of air flow openings in the opposed side walls;
- spacing the air flow openings along the longitudinal axis, and the air flow openings each providing an air flow area;
- directing air flow into the proximal end of the duct from the plenum and air-moving apparatus;
- and
- increasing the velocity of air as it flows along the longitudinal axis of the duct as the cross-section of the duct decreases while allowing some of the air flow to flow laterally outward from the duct through the opposed side walls and the flow areas formed by the air flow openings along the longitudinal axis of the duct.
