Abstract
A louver blade for a louver assembly includes a first section, a second section extending from the first section and including a crest of the louver blade, an extension extending from the second section to form a recess between the extension and the second section, and a protrusion extending from the second section toward the extension and configured to facilitate retention of the particles within the recess. The extension is configured guide particles into the recess in an installed configuration of the louver blade with the louver assembly.
Claims20
A louver blade for a louver assembly, the louver blade comprising:
- a first section;
- a second section extending from the first section and comprising a crest of the louver blade;
- an extension extending from the second section to form a recess between the extension and the second section, wherein the extension comprises a portion extending linearly over the crest, and wherein the extension is configured guide particles into the recess in an installed configuration of the louver blade with the louver assembly;
- and
- a protrusion extending from the second section toward the extension and configured to facilitate retention of the particles within the recess.
A louver assembly for a heating, ventilation, and air conditioning (HVAC) system, the louver assembly comprising:
- a louver blade comprising a first portion, a second portion extending from the first portion and forming a crest with the first portion, a first extension extending from the second portion on a first side of the louver blade to form a first recess between the second portion and the first extension, and a second extension extending from the second portion on a second side of the louver blade, opposite the first side, to form a second recess between the second portion and the second extension, wherein the first extension and the second extension overlap with one another along an axis crosswise to a direction of air flow through the louver assembly such that the second portion is positioned between the first extension and the second extension along the axis;
- and
- a jamb frame coupled to the louver blade, wherein the jamb frame comprises a first channel and a second channel, the first channel is aligned with the first recess relative to the direction of air flow through the louver assembly, and the second channel is aligned with the second recess relative to the direction of air flow through the louver assembly.
A louver blade for a louver assembly, the louver blade comprising:
- an upstream section comprising an incline portion;
- a midstream section comprising a decline portion extending from the incline portion to form a crest of the louver blade with the incline portion on a first side of the louver blade;
- a downstream section extending from the midstream section;
- an extension of the midstream section, wherein the extension extends in an upstream direction to form a recess between the extension and the midstream section on the first side of the louver blade, wherein the extension comprises a portion extending linearly over the crest;
- and
- a protrusion of the midstream section, wherein the protrusion extends toward the recess and is configured to retain liquid particles captured within the recess.
