Embodiment Construction

[0034] In the following specification, the same components are denoted by the same reference numerals throughout the specification and the drawings, respectively. For the sake of clarity and conciseness, the drawings are not necessarily to scale and certain features may be shown schematically or in general form.

[0035] Referring now to FIG. 1, there is shown one embodiment of the present invention including a high electric field dielectric air filtration system generally indicated at 30 . Filtration system 30 is shown inserted in the air flow path leading from air return duct 32 to the interior of cabinet 34 of air conditioning unit 36 ​​. The air conditioning unit 36 ​​includes conventional components such as a motor-driven fan 38, a furnace heat exchanger 39, and a heat exchanger 40, which may be part of a vapor compression air conditioning system and may be Reversible or irreversible to enable the air conditioning unit 36 ​​to provide one, or the other or both, of heated...

Abstract

An air filtration system, which may be included in and used in HVAC equipment, the system includes one or more high electric field dielectric filter units and an electric field charging unit held by a removable door in a support structure or Inside the enclosure, the removable door includes control circuitry and contactors that mate with corresponding contacts on the filter unit and the electric field charging unit for supplying a high voltage direct current potential to the corresponding units. Each filter unit includes a filter core comprising a row of stacked filter elements formed from dielectric sheets interconnected by elongated spacer ribs to form flow paths. The electric field charging unit and filter unit can be removed from the support or enclosure for cleaning or replacement by opening or removing the door. The interlock switch and field shorting mechanism are actuated during repair or replacement of system components.

Description

Background technique [0001] Filtration of the air circulated by heating, ventilation, and air conditioning (HVAC) equipment is increasingly a desired and necessary procedure. In the past, people have provided air filtration systems and devices associated with HVAC equipment to keep the equipment clean and efficient. However, in recent years the filtration of indoor air has become important to maintain and improve people's health and to keep interior spaces and homes cleaner. [0002] Air filter selection criteria include filter dust collection "efficiency", air pressure drop across the filter, usable space in the filtration system, dirt or dust holding capacity of the system, and of course initial construction and replacement costs. With regard to indoor air filtration in residential and commercial facilities, there is an increasing need for filters that can properly filter particulates. Conventional electrostatic electrofilter type filters are widely used, where a corona fi...
