Abstract
A particle agglomeration system for improving filtering capacity of an HVAC system is disclosed. The system may include a first plate. The first plate may include a first sound generator. The system may include a second plate. The second plate may include a second sound generator. The system may include a frame. The frame may be configured to position the first plate relative to the second plate. A standing sound wave may be formable between the first sound generator and the second sound generator.

A particle agglomeration system for agglomerating a fluid in a heating, ventilation and air conditioning (“HVAC”) system, the HVAC system comprising a duct, the duct having a rectangular shape, the duct having at least one dimension transverse to a direction of fluid flow through the duct of not less than 18 centimeters (“cm”), the particle agglomeration system comprising:
- a first printed circuit board (PCB), the first PCB comprising a first array of piezoelectric sound generators;
- a second PCB, the second PCB comprising a second array of piezoelectric sound generators;
- a first channel between the first and second PCBs;
- a third PCB, the third PCB comprising a third array of piezoelectric sound generators;
- a fourth PCB, the fourth PCB comprising a fourth array of piezoelectric sound generators;
- a second channel between the third and fourth PCBs;
- a target-sized frame that:
- positions the first PCB facing the second PCB at a first fixed distance therebetween, the first fixed distance being between 4 cm and 6 cm, the first fixed distance being oriented along the at least one dimension of the duct;
- positions the third PCB facing the fourth PCB at a second fixed distance therebetween, the second fixed distance being between 4 cm and 6 cm, the second fixed distance being oriented along the at least one dimension of the duct;
- and
- defines an unimpeded space, the unimpeded space having a third fixed distance therebetween, the third fixed distance being between 3 cm and 5 cm, the third fixed distance being oriented along the at least one dimension of the duct.
A particle agglomeration system for improving filtering capacity of a heating, ventilation and air conditioning (“HVAC”) system, the HVAC system comprising a duct, the duct having a rectangular shape, the duct having a first dimension transverse to a direction of fluid flow through the duct of not less than 7 centimeters (“cm”) and a second dimension transverse to the direction of fluid flow through the duct of not less than 18 cm, the particle agglomeration system comprising:
- a first plate comprising a first sound generator;
- a second plate comprising a second sound generator;
- a first channel between the first and second plate;
- a third plate comprising a third sound generator;
- and
- a fourth plate comprising a fourth sound generator,
- a second channel between the third and fourth plate;
- a target-sized frame configured to:
- position the first plate relative to the second plate at a first fixed distance such that a first standing sound wave is formable between the first sound generator and the second sound generator, the first fixed distance being between 4 cm and 6 cm, the first fixed distance being oriented along the second dimension of the duct;
- position the third plate relative to the fourth plate at a second fixed distance such that a second standing sound wave is formable between the third sound generator and the fourth sound generator the second fixed distance being between 4 cm and 6 cm, the second fixed distance being oriented along the second dimension of the duct;
- and
- define an unimpeded space between the first channel and the second channel, the unimpeded space having a third fixed distance therebetween, the third fixed distance being between 3 cm and 5 cm, the third fixed distance being oriented along the second dimension of the duct.
A method of retrofitting a heating, ventilation and air conditioning (“HVAC”) system, the HVAC system comprising a duct, the duct having a rectangular shape, the duct having at least one dimension transverse to a direction of fluid flow through the duct of not less than 18 centimeters (“cm”), the method comprising:
- assembling a target-sized frame that is sized to fit into the duct;
- positioning a first plate comprising a first sound generator into the target-sized frame;
- positioning a second plate comprising a second sound generator into the target-sized frame;
- and
- positioning a third plate comprising a third sound generator into the target-sized frame;
- positioning a fourth plate comprising a fourth sound generator into the target-sized frame;
- and
- securing the target-sized frame to the duct;
- wherein:
- the first and second plates are positioned at a first fixed distance such that a first channel is formed therebetween, the first fixed distance being between 4 cm and 6 cm, the first fixed distance being oriented along the at least one dimension of the duct;
- the third and fourth plates are positioned at a second fixed distance such that a second channel is formed therebetween, the second fixed distance being between 4 cm and 6 cm, the second fixed distance being oriented along the at least one dimension of the duct;
- and
- an unimpeded space is defined, the unimpeded space having a third fixed distance therebetween, the third fixed distance being between 3 cm and 5 cm, the third fixed distance being oriented along the at least one dimension of the duct.
