A system and method for controlling air quality within an indoor space are disclosed. An example system includes an air circulation unit that moves air through ductwork of a heating, ventilation, and air conditioning (HVAC) system and an air sanitization unit within the ductwork of the HVAC system that sanitizes air passing through the ductwork of the HVAC system. The system further includes an indoor air quality controller that controls a rate at which the air circulation unit moves the air through the ductwork of the HVAC system responsive to inputs received at the indoor air quality controller and controls an operational status of the air sanitization unit responsive to the inputs received at the indoor air quality controller.

System and method for air sanitization

A filter element for a heating, ventilation, and/or air conditioning (HVAC) system includes a filter media pack and a first support element. The filter media pack includes a pleated filter media. The first support element includes a connecting member that is coupled to the pleated filter media and includes at least a portion of a curved wall that curves above a central axis that extends substantially parallel to an insertion direction of the filter element into a filter housing. The first interface member is located at a distal end of the connecting member and defines a first support ledge that is disposed over the connecting member and that extends substantially parallel to the insertion direction.

A damper regulator for controlling the opening/closing characteristics of an HVAC damper has a swing arm coupled to the shaft on which the damper pivots. The swing arm has an arm carriage mounted to translate on the swing arm as the swing arm pivots, and a biasing spring connects the arm carriage to the damper regulator's housing, or to another suitable anchor. The translation of the arm carriage effectively adapts the characteristics of the biasing spring so that the damper need not be subjected to ever-increasing pressure to achieve greater airflow, or so that other damper opening characteristics can be achieved.

Damper with adjustable resistance to blade motion

A collapsible air cleaner filter is provided. The filter includes a pleated media filter having a first end, a second end, and a filter media extending between the first and second ends, wherein the filter media includes a first plurality of flexible end portions and a second plurality of flexible end portions, the first and second plurality of flexible end portions are separated by a plurality of pleats, and the filter media extends a first length between the first and second plurality of flexible end portions, and an end member coupled to the first end of the pleated media filter, the end member extending a second length parallel to the first length, the first length being greater than the second length.

Collapsible extended surface filter and air cleaner system using collapsible extended surface filter

An air cleaner comprises an enclosing structure having support members spaced a distance from top and bottom walls. A collapsible extended surface pleated media filter has end members and a pleated mechanical media filter. The end members have an outer surface and a thickness that is based on the distance that the support surfaces are spaced from the top and bottom walls to provide an effective seal against air flowing around the collapsible filter. The end members can have a seal structure provided on the outer surface that interacts with the top or bottom wall. The collapsible filter optionally includes flexible support member(s) on or in the pleated mechanical media filter that assist in keeping the pleats open. The pleated mechanical media filter can extend beyond the end member(s) and interact with portions of the frame to provide an effective seal against air flowing around the collapsible filter.

A selectively removable door assembly is provided for completing an air filter housing having a series of interconnected walls for enclosing an air filter, certain of the walls being formed with retaining pockets. The door assembly comprises a door having a main portion and opposed end portions. Each of the end portions is provided with a ridge engageable with a respective one of the pockets on the walls for retaining the door on the housing. At least one of the ridges is resiliently and slidably mounted on the door in a biased snap-fit in its respective pocket such that pushing against the bias of the resiliently mounted ridge will permit movement of the other ridge out of its respective pocket and allow the removal of the door to access the air filter.

A one-piece framework for holding the filter media of an air filter includes a pair of end walls integrally connected to a pair of frame members by a living hinge so that they may be pivotally moved between an assembled position and an unassembled position. A pair of sidewalls are integrally connected to the frame members by a living hinge only at their outermost ends so that they, too, may be pivotally moved between their assembled and unassembled position. Each of either of the sidewalls or end walls is provided with a tab-type latch which includes a button undercut at least a peripheral portion thereof. Each of the other sidewalls or end walls has an opening formed therethrough. The opening is defined by a wall shaped in accordance with and frictionally surrounding the undercut button in a snap-fit to hold the sidewalls to the end walls in an assembled state.

Latch arrangement for air filter housing

A mounting system for suspending an appliance from a supporting structure includes an elongated U-shaped bracket and a plurality of fasteners for securing the bracket to a supporting structure. A mounting pin is disposed toward one end of the bracket and a mounting hook is disposed toward one end of the appliance so that the hook may be placed over the mounting pin and the appliance can be pivotally suspended from the bracket. A locking means is provided toward one end of the appliance so that the appliance may be pivoted about the mounting pin and locked onto the bracket.

Appliance mounting system

A frame for holding an evaporative pad in the base of a humidifier includes side walls, base and a top that define an evaporative pad holding chamber. Each of the side walls, base and top is provided with a flange that extends inwardly toward the opening and is engageable with a lip on the base to form an air seal. The flange is provided with a rib portion that extends outwardly away from the pad chamber and is dimensioned so as to create a gap between the rib and any adjacent base surface in order to inhibit the migration of mineral deposits from the pad to the base.

Wall outlet box for a central vacuum cleaning system

A cutout (4) is made in a room wall (2) and flexible tubing (13) connected to a vacuum conduit (12) is pulled therethrough. A box (1) is attached to the tubing and includes a frame portion (15) for surrounding the cutout, and inwardly recessed portion (18) having side and top and bottom walls (19-22) and a back wall (23), and outwardly and inwardly extending annular connector flanges (25, 26) for connecting to the vacuum wand and the conduit flexible tubing. After the conduit tubing and box are connected, the box is pushed inwardly so that its recessed portion extends through the cutout into the wall. A slot (29, 30) is provided in each vertical sidewall of the box with the slot extending into the back wall so that it is generally L-shaped in section. A generally Z-shaped clip (33) having a long leg (35) and short leg (34) joined by a web (36) is provided for each slot. The short leg is inserted through a slot so that the short leg engages the rear wall face, the web extends forwardly along the side wall of the recess, and the long leg extends across the recess toward the outwardly extending annular flange. The clips make it possible to accommodate various wall thicknesses and cannot fall into the wall during installation. Subsequently, screws are utilized to fixedly mount the box to the wall. A door (27) is pivotally mounted to the box to cover the interior thereof when the box is not in use. The door seals against the outer edge of the outwardly extending flange to prevent air leakage when the system is being used in other rooms. The door is formed (44) for easy engagement and manipulation by the user's hose.
