摘要:
An improved humidifier system for adding humidity to an air stream of an HVAC system. The humidifier system includes an air path that is configured to accept air from a first HVAC duct and return air to a second HVAC duct. A damper is disposed in the air path to selectively substantially block the flow of air in the air path, or to substantially not block the flow of air in the air path. In some cases, the damper may be a motorized damper, and the humidifier system may include a controller that is configured to cause the motorized damper to not substantially block the flow of air in the air path during a call for humidifier operation, and to substantially block the flow of air in the air path after the call for humidifier operation ends. Alternatively, the damper may be manually actuated, and an HVAC controller may be configured to notify when the damper should be moved (e.g. between seasons).

A humidifier for adding humidity to an air stream of an HVAC system includes a housing configured to be mounted to a surface of an HVAC duct. The housing may be configured to hold a humidifier pad in an operating position. The housing may direct air through the humidifier pad from a first major surface to a second major surface of the pad. In the operating position, the first and second major surfaces of the humidifier pad may be substantially non-parallel with the surface of the HVAC duct when the housing is mounted to the surface of the HVAC duct. In some cases, this may provide a more compact design. In some cases, a centrifugal fan, rather than an axial fan, may be used to draw air into the humidifier from the HVAC duct. The use of a centrifugal fan may reduce the noise associated with the operation of the humidifier.

A humidifier pad assembly for a humidifier that is configured for adding humidity to an air stream of an HVAC system of a building or other structure. The humidifier pad assembly may include a frame for holding a replaceable humidifier pad within the housing of the humidifier. The frame may be structured to hold the replaceable humidifier pad within the housing such that a back major surface of the replaceable humidifier pad generally faces the back side of the housing, and a front opposing major surface of the humidifier pad generally faces the front side of the housing. The frame may further be structured to permit removal and replacement of the replaceable humidifier pad through the front side of the frame. In some cases, the housing may be configured such that the frame (and the replaceable humidifier pad) may be slid out of apertures in the right side and/or left side of the housing. In some instances, the humidifier may include a drain funnel structured to collect water from substantially the entire bottom side of the frame and direct the water to a water drain. The drain funnel may be structured to allow the frame to be slidably moved (e.g. in the left and/or right direction) relative to the drain funnel and removed from the housing through at least one of the left side or the right side of the housing. In some cases, a water distributor is releasably attachable to the frame along a top side of the frame.

A controller equipped with a controller interface configured to accept one or more input parameters is disclosed, including methods for programming such devices. An illustrative controller interface may include a number of knobs, slides, buttons, or other input means for setting various set-points within the controller that can be used to control one or more HVAC system components of a building or structure. The input parameters may correspond directly to physical parameters of the building or structure being regulated, allowing the user to program the controller without having an extensive knowledge of HVAC systems or their operation.

A humidifier for adding humidity to an air stream of an HVAC system includes a housing configured to be mounted to a surface of an HVAC duct. A back side of the housing may be positioned adjacent to an opening in the surface of the HVAC duct, and the housing may be configured to hold a humidifier pad in an operating position. The housing may define a first air flow path from a first side of the humidifier pad to the opening in the surface of the HVAC duct when the housing is mounted to the surface of the HVAC duct. The housing may further define a second air flow path from a second side of the humidifier pad to a bypass aperture. At least part of the second air flow path may be defined by a bypass duct member. The bypass duct member may be field-reconfigurable between at least a first position resulting in the bypass aperture being located at a first location, and a second position resulting in the bypass aperture being located at a second location. In some cases, the first and second locations are on the left and right sides, respectively, of the humidifier housing.

A humidifier for an HVAC system includes a replaceable humidifier pad, and a housing for holding the replaceable humidifier pad in an operating position during operation of the humidifier. The back side of the housing may define an air flow aperture that is in fluid communication with the replaceable humidifier pad when the replaceable humidifier pad is in its operating position. In some instances, the right side of the housing may define a first aperture that is sufficient in size to remove the replaceable humidifier pad from the housing, and to install a new replaceable humidifier pad. Likewise, the left side of the housing may define a second aperture that is sufficient in size to remove the replaceable humidifier pad from the housing, and to install a new replaceable humidifier pad. The humidifier may also include a first cover member for covering the first aperture when the replaceable humidifier pad is in its operating position, and a second cover member for covering the second aperture when the replaceable humidifier pad is in its operating position. In some cases, an aperture and cover may also be provided on the front and/or top sides of the housing so that the replaceable humidifier pad may be replaced from the front and/or top sides of the housing.

A deep format filter element has a peripheral frame with outwardly protruding mounting flanges. The mounting flanges simulate the periphery of a shallow format filter element to allow the deep format filter element to replace the shallow format filter element in many situations. The frame design allows the entire frame to be formed of cardboard and still provide adequate rigidity and strength. The frame includes at least a first cardboard sheet forming individual sides of the frame and panels of the mounting flange. The first cardboard sheet includes for each mounting flange at least two inside folds defining edges of the mounting flange's end panel and first and second side panels. An outside fold defines the second side panel of the mounting flange.
