INTEGRATED AUXILIARY SYSTEM FOR DIFFUSER OF AN HVAC SYSTEMCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from and the benefit of U.S. Provisional Application No. 63 / 522,062, entitled “INTEGRATED AUXILIARY SYSTEM FOR DIFFUSER OF AN HVAC SYSTEM,’" filed June 20, 2023, which is hereby incorporated by reference in its entirety7for all purposes.BACKGROUND

[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and / or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0003] Heating, ventilation, and / or air conditioning (HVAC) systems are utilized in residential, commercial, and industrial environments to control environmental properties, such as temperature and humidity7, for occupants of the respective environments. Generally, an HVAC system may control environmental properties by controlling a supply air flow delivered to the environment. For example, the HVAC system may place the supply air flow in a heat exchange relationship with a refrigerant of a vapor compression circuit to condition the supply air flow. A HVAC system may control environmental properties by supplying an air flow to the environment via a diffuser. For example, a diffuser may be installed in a ceiling of a room and may be configured to receive air from a duct of the HVAC system. The diffuser may direct and diffuse the air into the room. Meanwhile, ceiling space may be allocated to accommodate various ceiling mounted devices, such as light fixtures, speakers, and cameras. Unfortunately, multiple objects or components mounted to a ceiling may elicit a sense of visual clutter that may aesthetically degrade the environment. Therefore, improved installation of diffusers and other devices installed with or for a room are desired.SUMMARY

[0004] A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below.

The diffuser is configured to be disposed within the opening and mounted to the ceiling in an installed configuration. The integrated diffuser assembly further includes an auxiliary' electronic device coupled to the diffuser. The auxiliary' electronic device is configured to be at least partially disposed within the opening with the diffuser and above a surface of the ceiling in the installed configuration.

[0006] In an embodiment, a heating, ventilation, and air conditioning (HVAC) system includes a linear slot diffuser coupled to an auxiliary electronic device via a spline clip. The diffuser includes a first boss feature extending along a length of the diffuser. The auxiliary electronic device includes a second boss feature aligned with the first boss feature. The spline clip extends partially into the first boss feature and partially into the second boss feature.

[0007] In an embodiment, an integrated diffuser assembly includes a linear slot diffuser, a lighting element disposed within a device housing, and one or more spline clips configured to adjoin the device housing and the linear slot diffuser in an end-to-end arrangement.BRIEF DESCRIPTION OF THE DRAWINGS

[0020] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0021] When introducing elements of various embodiments of the present disclosure, the articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be noted that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

[0022] As mentioned above, a diffuser may be used to distribute air to an environment (e.g., room, indoor environment) as part of an HVAC system that conditions the environment. In some embodiments, the diffuser may be a component of an air distribution system and may be located at an outlet of a duct, such that the diffuser receives an air flow from the air distribution system via the duct. For example, the diffuser may be coupled to the duct, or the diffuser may be coupled to another component of the air distribution system, such as a plenum space (e.g., plenum box) connected to the duct. Upon receiving the air flow, the diffuser may change a velocity and / or a static pressure of the air flow and dispense a diffused air flow to the environment. In some instances, a ceiling or wall of the environment may include an opening (e.g.. a slot, a cavity, an aperture) for directing air therethrough, and the diffuser may be disposed at or within the opening. For example, the diffuser may span the opening in the ceiling or wall, and the diffuser may receive the air flow from ductwork via the opening to enable air to flow from the opening into the room. The diffuser may be configured to enclose, encase, encompass, border, or otherwise adjoin the opening such that the air flow may pass through the opening and through the diffuser. In some cases, multiple (e.g., 2, 3, 4, 5, or more) diffusers may be located at the opening. For example, multiple diffusers may be conjoined to span the opening.

[0023] Meanwhile, the environment may include or be associated with other systems (e.g., lighting systems, audio systems, wireless networking systems, video systems, camera systems, fire detection systems, fire suppression systems, etc.) that are implemented for various purposes(e.g., related or unrelated to the HVAC system). Such systems may also be installed in or on the ceiling or wall of the environment. For example, the ceiling of a room may include one or more diffusers, light fixtures, Wi-Fi routers, audio speakers, sprinklers, sensors, cameras, and the like. A visual presence or overabundance of these devices and systems in a ceiling may contribute to material or aesthetic clutter as the devices compete physically and / or visually to occupy a limited space provided by the ceiling. In other words, a ceiling having clean and seamless appearance may be preferred to a ceiling that contains a number of visually apparent devices installed on and / or in the ceiling. Accordingly, certain systems may include diffusers, such as architectural diffusers, which may be designed to appear inconspicuous and harmonious with the environment. For example, a linear slot diffuser may encase or occupy an elongated, narrow opening in the ceiling, such that an observer in the room may merely perceive a thin slot in the ceiling rather than a visually obtrusive apparatus.

[0024] Keeping this in mind, it is presently recognized that incorporating auxiliary' systems and electronic devices (e.g., auxiliary systems, auxiliary’ devices) with a diffuser as an integrated assembly may enable the auxiliary devices (e.g., lights, speakers, sprinklers, routers, cameras) to be “hidden” or generally concealed by and / or in the diffuser, thereby reducing visual obtrusions in a ceiling or wall. As described in further detail below, embodiments of the present disclosure include an assembly (e.g.. diffuser assembly) having an auxiliary device (e.g.. auxiliary electronic device) in the form of a device module coupled to one or more segments of a diffuser. In some embodiments, the diffuser may encase an opening formed in a ceiling or wall of a room to enable flow of air therethrough. The device module may be situated within the diffuser and / or the opening such that the device module is substantially out of view from occupants of the room. The device module may be coupled to the diffuser in a manner that does not involve substantial or appreciable modification of a physical appearance of the opening and / or the diffuser. Accordingly, present embodiments enable installation of diffusers and auxiliary devices or systems in an integrated manner. Further, the techniques disclosed herein enable integrated operation of the diffusers and auxiliary systems. In this way, diffusers and auxiliary systems may be installed and utilized with minimal detraction from aesthetic appeal of the environment. While the discussion below describes the present techniques in a ceiling-mounted context, it should be appreciated that systems and elements thereof hereinafter described as being disposed along a ceiling may be adapted for installation along a wall, a floor, or other suitable surface.

[0025] Turning now to the drawings, FIG. 1 illustrates an embodiment of a heating, ventilation, and / or air conditioning (HVAC) system for environmental management that may employ one or more HVAC units. As used herein, an HVAC system includes any number of components configured to enable regulation of parameters related to climate characteristics, such as temperature, humidity , air flow, pressure, air quality , and so forth. For example, an “HVAC system” as used herein is defined as conventionally understood and as further described herein. Components or parts of an “HVAC system” may include, but are not limited to, all, some of, or individual parts such as a heat exchanger, a heater, an air flow control device, such as a fan, a sensor configured to detect a climate characteristic or operating parameter, a filter, a control device configured to regulate operation of an HVAC system component, a component configured to enable regulation of climate characteristics, or a combination thereof. An “HVAC system” is a system configured to provide such functions as heating, cooling, ventilation, dehumidification, pressurization, refrigeration, filtration, or any combination thereof. The embodiments described herein may be utilized in a variety of applications to control climate characteristics, such as residential, commercial, industrial, transportation, or other applications where climate control is desired.

[0026] In the illustrated embodiment, a building 10 is air conditioned by a system that includes an HVAC unit 12. The building 10 may be a commercial structure or a residential structure. As shown, the HVAC unit 12 is disposed on the roof of the building 10; however, the HVAC unit 12 may be located in other equipment rooms or areas adjacent the building 10. The HVAC unit 12 may be a single package unit containing other equipment, such as a blower, integrated air handler, and / or auxiliary heating unit.

[0027] The HVAC unit 12 is an air cooled device that implements a refrigeration cycle to provide conditioned air to the building 10. Specifically, the HVAC unit 12 may include one or more heat exchangers across which an air flow is passed to condition the air flow before the air flow is supplied to the building. In the illustrated embodiment, the HVAC unit 12 is a rooftop unit (RTU) that conditions a supply air stream, such as environmental air and / or a return air flow from the building 10. After the HV AC unit 12 conditions the air, the air is supplied to the building 10 via ductwork 14 extending throughout the building 10 from the HVAC unit 12. For example, the ductwork 14 may extend to various individual floors or other sections of the building 10. In certain embodiments, the HVAC unit 12 may be a heat pump that provides both heating and cooling to the building with one refrigeration circuit configured to operate indifferent modes. In other embodiments, the HVAC unit 12 may include one or more refrigeration circuits for cooling an air stream and a furnace for heating the air stream.

[0028] A control device 16, one type of which may be a thermostat, may be used to set the temperature of the conditioned air. The control device 16 also may be used to control the flow of air through the ductwork 14. For example, the control device 16 may be used to regulate operation of one or more components of the HVAC unit 12 or other components, such as dampers and fans, within the building 10 that may control flow of air through and / or from the ductwork 14. In some embodiments, other devices may be included in the system, such as pressure and / or temperature transducers or switches that sense the temperatures and pressures of the supply air, return air, and so forth. Moreover, the control device 16 may include computer systems that are integrated with or separate from other building control or monitoring systems, and even systems that are remote from the building 10.

[0029] The ductwork 14 may include one or more duct outlets 18 configured to enable discharge of air (e.g., supply air) into the building 10. As shown, a diffuser 20 may be fluidly coupled to each duct outlet 18 to enable discharge conditioned air from the ductwork 14 to a conditioned space (e.g., a room) of the building 10. For example, the diffuser 20 may be configured to receive a flow of supply air from the ductwork 14 and change the velocity, static pressure, turbulence, and / or other properties of the supply air before the supply air is provided to the conditioned space. In some embodiments, two or more conjoined diffusers (e.g., a first diffuser and a second diffuser, a diffuser assembly) may be commonly located at one of the duct outlets 18. Although the present disclosure describes an assemblage of air-diffusing structures as individual diffusers (e.g., diffuser 20) in a conjoined configuration, it should be appreciated that the assemblage may be considered a single diffuser having multiple segments. For example, a first diffuser and a second diffuser described below' may be substantially similar to a first segment (e.g., portion) and a second segment (e.g., portion) of a common diffuser. The first diffuser and the second diffuser may be coupled end-to-end with one another to form a continuous length of diffusers. Further, it should be appreciated that the techniques disclosed herein may be utilized with diffusers (e.g., diffuser 20) configured to discharge air flow into a room, as well as diffusers configured to exhaust air flow' from a room.

[0030] The diffuser 20 may be configured to receive a high velocity air flow from the ductwork 14 and redirect the air flow- in one or more directions (e.g., into a room) at an adjusted (e.g., lower) velocity'. For example, one or more structures (e.g., bars, plates, flaps, grilles,channels, plaques, panels, dampers) within the diffuser 20 may deflect or partially divert the air flow, thereby causing the air flow to disperse and flow into the room. Furthermore, the diffuser 20 may change the cross-sectional area of the air flow and thereby change an average velocity of the air flow. In this way, conditioned air may enter the space with a desired (e.g., more uniform) distribution and without unwanted drafts. Moreover, noise generated by HVAC system (e.g., HVAC unit 12) may be reduced (e.g., damped) by altering the air flow. In other embodiments, the diffuser 20, such as a jet diffuser, may be configured to discharge air into a room in a concentrated direction. In any case, the diffuser 20 may alter or redirect the air flow in a desired manner before or as the air is distributed to the conditioned space.

[0031] FIG. 2 illustrates an embodiment of a room 30 serviced by an HVAC system 32. The HVAC system 32, which may include an embodiment of the HVAC unit 12, may condition a flow of air and direct the air to the room 30 via the ductwork 14. The ductwork 14 may terminate at the duct outlet 18, and the duct outlet 18 may be fluidly connected to one or more diffusers 20. As shown, the duct outlet 18 connects to diffusers 20 including a first diffuser 34 and a second diffuser 36. However, the presently disclosed techniques may be utilized with HVAC systems having any suitable number of diffusers 20 connected to any suitable number of duct outlets 18. In some embodiments, the duct outlet 18 may be fluidly coupled to the diffusers 20 via a housing 38 (e.g., plenum housing) configured to receive air from the ductwork 14 and to direct the air to the diffusers 20. That is. the housing 38 may be coupled to the duct outlet 18 and the diffuser 20 may be coupled to the housing 38, such that the housing 38 is an intermediate structure fluidly coupling the duct outlet 18 and the diffusers 20. In other embodiments, the housing 38 may be part of the ductwork 14 or the diffusers 20. or the ductwork 14 may directly connect to one or more the diffusers 20 without the housing 38. In any case, the diffusers 20 may receive the air flow from the ductwork 14 and dispense a diffused air flow 40 to the room 30. Accordingly, an occupant 42 standing within the room 30 may experience comforts of more evenly distributed conditioned air.

[0032] As shown, the diffusers 20 may cooperatively and at least partially span an opening 44 in a ceiling 46 of the room 30. The opening 44 may be formed in the ceiling 46 to enable discharge of air from the diffusers 20 and into the room 30. That is, the diffusers 20 partition the room 30 from the ductwork 14 while enabling air to flow therebetween via the opening 44. In some embodiments, the diffusers 20 may be linear slot diffusers, and the opening 44 may beelongated and relatively narrow. As will be appreciated, linear slot diffusers may provide a more aesthetic architectural design compared to other types of diffusers.

[0033] As discussed above, the opening 44 may further accommodate a device module 48 (e.g., auxiliary electronic device, lighting element). The device module 48 may be coupled to one or more of the diffusers 20, such that the device module 48 is recessed within the ceiling 46 along with the diffusers 20 (e.g., above a plane defined by the ceiling 46). The device module 46 may be similarly exposed to the room 30 via the opening 44. The device module 48 may include any suitable device associated with the room 30, such a device that may otherwise be mounted on the ceiling 46. For example, the device module 48 may include a light fixture. Wi-Fi router, audio system, sprinkler, sensor, camera, power outlet, projector, carbon monoxide sensor, carbon dioxide sensor, smoke detector, wireless connectivity gateway, or other device associated with the room 30. In accordance with present techniques, the device module 48 and the diffuser 20 may be integrated with one another and / or cooperatively mounted within the ceiling 46. In this way, the diffuser 20 and the device module 48 may positioned within the ceiling 46 and may be exposed to the room 30 via the opening 44 with improved aesthetics (e.g., relatively hidden from view by occupants 42 of the room 30).

[0034] FIG. 3 is a schematic perspective view of an embodiment of the diffusers 20 (e.g., diffuser assembly) connected to the ductwork 14 via the duct outlet 18. In some embodiments, the diffusers 20 may be coupled to the ductwork 14 via the housing 38. For example, housing 38 may define a plenum space configured to receive air flow from the ductwork 14, and the diffusers 20 may be coupled to and / or disposed within the housing 38. The illustrated embodiment also includes the device module 48 (e.g., auxiliary system, auxiliary device), which may be positioned between the first diffuser 34 and the second diffuser 36. As discussed in detail below with reference to FIG. 4, the device module 48, the first diffuser 34, the second diffuser 36, and / or any number of diffusers 20 may be form an assembly (e.g., diffuser assembly, integrated diffuser assembly) configured to be installed (e.g., within the opening 44) and utilized to provide one or more features or characteristics associated with the room. Indeed, the assembly having the device module 48, the first diffuser 34, the second diffuser 36 may be exposed to the room 30 via a common opening (e.g., opening 44), which may provide a more aesthetic appeal to occupants 42 of the room 30 and may provide improved concealment of the device module 48 compared to more traditional (e.g., separate) installations of such components with the room 30. Additionally, by integrating the device module 48 with thediffusers 20, installation of the device module 48 may be improved (e.g.. simplified, at a reduced cost, and so forth).

[0035] FIG. 4 is a perspective view of an embodiment of an integrated diffuser assembly 50 (e g., integrated auxiliary system), which may be installed above the ceiling 46 and may be exposed to the room 30 via the opening 44 formed in the ceiling 46. In the illustrated embodiment, the integrated diffuser assembly 50 includes the device module 48 integrated between two diffusers 20 (e.g., diffuser segments). In particular, the device module 48 is disposed between the first diffuser 34 and the second diffuser 36 (e.g., disposed between respective ends of the first and second diffusers 34 and 36). In some embodiments, the first diffuser 34, the second diffuser 36, and / or the device module 48 may be adjoined end-to-end with one another. For example, a first end of the first diffuser 34 may be adjoined to a first end of the device module 48. Additionally, a second end of the device module 48 may be adjoined to a first end of the second diffuser 36. Thus, the first diffuser 34 may extend along a first length 51 of the opening 44, the second diffuser 36 may extend along a second length 53 of the opening 44, and the device module 48 may be situated between the first diffuser 34 and the second diffuser 36. As shown, the diffusers 20 are linear slot diffusers, although aspects of the present disclosure may apply to other ty pes of diffusers 20, such as bar grille diffusers and plaque diffusers. Other embodiments of the integrated diffuser assembly 50 may include more or fewer diffusers 20 and / or device modules 48.

[0036] As shown, each diffuser 20 includes a main body 52 (e.g., frame), an air flow controller 54 (e.g., pattern controller, flow pattern controller, air adjusting component) disposed within the mam body 52, and border flanges 56 coupled to the main body 52. The main body 52 may be formed from a metal extrusion or other suitable material. In some embodiments, the main body 52 may include additional features configured to accommodate mounting hardware, spline clips, airflow manipulating accessories, and so forth. The air flow controller 54 may an adjustable flap, panel, plate, or other component configured to adjust flow of air through the diffuser 20 (e.g., and into the room 30). For example, the air flow controller 54 may be shaped and / or oriented (e.g., adjustably positioned) to diffuse the air flow discharged by the diffuser 20 in a particular manner. In some embodiments, the air flow controller 54 maybe adjusted according to an installer’s or user’s preference. In an installed configuration, the border flanges 56 may be positioned flush against the ceiling 46. such that the border flanges 56 encase a border of the opening 44 and conceal components disposed therein. The borderflanges 56 may define a slot 57 in the space between the border flanges 56 through which the air flow exits the diffuser 20. That is. the diffuser 20 may direct the air flow into the conditioned space (e.g., the room 30) through the slot 57 between the border flanges 56. As such, the main body 52 of the diffuser 20 may be partially or entirely recessed into (e.g., above) the ceiling 46. To the occupant 42, visible evidence of the integrated diffuser assembly 50 may be generally limited to the apparent slot 57 or multiple slots in the ceiling 46, encased by the border flanges 56. Thus, the ceiling 46 may appear to have a generally continuous surface with minimal visual appearance of the diffuser 20 other than the encased opening 44. In this way, the presence of the diffusers 20 and the device module 48 may be inconspicuous or otherwise aesthetically compatible with a design of the environment and / or the room 30.

[0037] Each diffuser 20 may include two framing members 120 extending along the length of the diffuser 20 and spaced apart from one another by a spacer 122 (e.g., spreader). The spacer 122 may be a rigid component (e.g., plate) extending between the two framing members 120 to hold them apart. The diffuser 20 is configured to direct an air flow from the plenum or ductwork 14 through the space between the framing members 120 and into the conditioned space. The diffuser 20 (e.g., each framing member 120) has a profile (e.g., cross-section) that enables attachment of the diffuser 20 to the ceiling 46, to other diffusers 20, to the spacer 122, and / or to the device module 48. For example, the diffuser 20 may include boss features (e.g., inset surfaces, recesses, rails, channels) configured to engage with other components and / or structures to couple the diffuser 20 therewith. The boss features may include a channel 124 (e.g., joining slot, rail) formed by protrusions 125 (e.g., ledges, rails) extending along the length of each framing member 120. The channel 124 may receive (e.g., via insertion) various clips or supports that facilitate attachment of the first channel 124 to other structures. For example, the channel 124 may be configured to receive one or more ceiling clips. The ceiling clip may slide into the channel 124 and include a flange through which the ceiling clip may be screwed into a ceiling frame (e.g., support beam, stud) above the ceiling 46. The diffuser 20 may include additional channels 128 configured to receive other components, such as hanger clips 158, as shown in FIG. 10.

[0038] Each framing member 120 may include a corresponding border flange 56 positioned below the channel 124. A bottom surface (e.g., an exposed surface, a surface exposed to the room 30) of the ceiling 46 (e.g., ceiling tile) may abut a top surface of the border flange 56. A top surface of the ceiling 46 may abut one of the ledges 125 or other boss feature of the framingmember 120. Indeed, the framing member 120 may be retained to the ceiling 46 by a cavity (e.g., mounting channel, gap) formed between the border flange 56 and the ledge 125. In this way, the diffuser 20 may be supported above the ceiling 46.

[0039] In some embodiments, the diffusers 20 may define or include a plenum box (e.g., housing 38) having an air inlet opening. A fan or blower may be operated to force an air flow to pass from the ductwork 14 to the plenum box via the air inlet opening. Subsequently, the air flow may exit the plenum box via the attached diffusers 20. In other words, the plenum box may receive air from the ductwork 14 and direct the received air into the main body 52 of the diffuser 20.

[0040] In another embodiment, the diffusers 20 may be bar grille diffusers having a grille configured to extend across a length of the opening 44. Like the linear slot diffuser, a bar grille diffuser may occupy and distribute air along a length of the opening 44 (e.g., a portion of the ceiling 46). Bar grille diffusers may also have the border flanges 56 configured to be flush against the ceiling 46 around the opening 44 in an installed configuration. The grille may cover the opening 44 and include multiple bars and / or multiple slots extending the length and / or width of the bar grille diffuser. The multiple bars across the grille may obstruct solid objects from passing through the diffuser. To the occupant 42, visible evidence of the integrated diffuser assembly 50 having bar grille diffusers may be generally limited to the sight of the grille extending along the ceiling 46. In this way, the presence of the bar grille diffuser may be inconspicuous or otherwise aesthetically compatible with a design of the environment and / or the room 30 having the integrated diffuser assembly 50.

[0041] As mentioned above, the device module 48 may be integrated as a component of the integrated diffuser assembly 50. That is, the device module 48 may be integrated with (e.g., coupled to, mounted to) the diffusers 20, such that the integrated diffuser assembly 50 may be mounted within the ceiling 46 and may be exposed to the room 30 via the opening 44 (e.g.. a common opening). Additionally, the integrated diffuser assembly 50 may be installed as a common or integrated unit, which may enable common (e.g., simplified) installation of the diffusers 20 and device module 48 together (e g., at the same time).

[0042] In the illustrated embodiment, the device module 48 includes a device housing 60 and an integrated device 61 located within the device housing 60, such as one or more lights, sensors, cameras, sprinklers, speakers, and so forth. The device housing 60 may be anystructure (e.g., box. container, extrusion) suitable for housing components of the device module 48. The device housing 60 may have walls enclosing one or more cavities in which the components (e.g., integrated device 61) of the device module 48 may be housed. The device module 48 may also include a driver component 62 configured to act as an interface between the integrated device 61 and other components in the system. For example, the driver component 62 may be communicatively coupled to a control system, feedback system, user interface, and / or other components associated with the room 30 and / or occupants 42 of the room 30.

[0043] Additionally, the device module 48 may include a power connector 64 configured to enable supply of power to the device module 48 from a power source (e.g., plug outlet, power utility, building power system). Power for the device module 48 may be of a different voltage or current than power for the HVAC system 32. For example, the device module 48 may operate using low-voltage power. Accordingly, electrical installation of the device module 48 may be performed by an HVAC technician instead of an electrician (e.g., a master electrician). In some embodiments, the diffusers 20 and apparatuses associated therewith may be installed during installation of the ceiling 46. The device module 48 may likewise be installed when the diffusers 20 are installed. Indeed, the integrated diffuser assembly 50 of the present disclosure enables joint installation of the diffusers 20 and device module 48, which may reduce installation complexity and / or costs associated with installation. For example, the integrated diffuser assembly 50 may be assembled prior to installation within the ceiling 46. In another embodiment, the device module 48 may be installed (e.g., attached, detachably coupled) to the diffusers 20 after the diffusers 20 and / or ceiling 46 are installed. In this way, the device module 48 may be more conveniently installed, maintained, repaired, removed, and / or replaced, such as without involvement of an electrician.

[0044] In existing systems (e.g., without the device module 48), the first diffuser 34 may be configured to couple to the second diffuser 36 via one or more spline clips 58 (e.g., connectors, brackets, links). Each spline clip 58 may be a structural bracket (e.g., straight bracket) or brace configured to slide, clip, bolt, screw, insert, or otherwise attach to respective surface of the first diffuser 34 and / or the second diffuser 36. For example, one end of the spline clip 58 may be inserted into a channel 124 (e.g.. joining slot) of the first diffuser 34, while the other end of the spline clip may be inserted into a channel 124 of the second diffuser 36. such that the diffusers 20 are secured to each other and aligned in a desired fashion via the splineclip 58. The channels 124 of each diffuser 20 may be a boss or extrusion feature of the diffuser 20 designed to accommodate (e.g., receive, capture, retain) the spline clip 58. In this way, a series of diffusers 20 may be joined end-to-end to provide a desired a path of air flow distribution along the ceiling 46.

[0045] An advantage of the present disclosure is the integration of the device module 48 in the integrated diffuser assembly 50 using existing accessories and features of the diffusers 20, such as the spline clips 58. In some embodiments, spline clips 58 used to connect diffusers 20 in existing systems may be dual-purposed to connect the device module 48 to diffusers 20 or other device modules in addition to connecting the first diffuser 34 and the second diffuser 36, as discussed above. Like the diffusers 20. the device module 48 may be configured to couple to one or more diffusers 20 via the one or more spline clips 58. The device housing 60 may similarly include a joining slot, channel, pocket, cavity, aperture, or other structural feature (e.g., boss feature) into which the spline clips 58 may slide or clip to couple to the device module 48. For example, the device housing 60 may include boss features similar to those of the framing members 120 of the diffuser 20. Indeed, additional boss features of the device housing 60 may include a corresponding channel 126 (e.g., joining slot) configured to receive the one or more spine clips 58. The spine clip 58 may slide partially (e.g., substantially halfway) into the channel 124 of the framing member 120 at one end of the spine clip 58 and partially into the corresponding channel 126 of the device housing 60 at the opposite end of the spine clip 58. In this way, the spine clip 58 may join the device housing 60 to the diffuser 20. The device housing 60 may further include border flanges similar to the border flanges 56 of the diffusers 20. When the diffuser 20 and the device module 48 are coupled via the spine clip 58, the border flanges of the device housing 60 may align with the border flanges 56 of the diffuser 20 to provide the appearance of a continuous surface. In this way, the segmentation between diffusers 20 and the device module 48 may be less discernable when viewed from the room 30.

[0046] Generally, spline clips 58 may be inserted into the channels 124 and 126 to join one diffuser 20 to another diffuser 20, the diffuser 20 to the device module 48, or the device module 48 to another device module 48. The spline clips 58 may support, align, and attach each of these components to one another by providing end-to-end couplings that can be readily customized (e.g.. reconfigured) based on a particular design of an installation.

[0047] In some embodiments, the device housing 60 may receive, at one end of the device housing 60, one end of a first spline clip 58, such that the other end of the first spline clip may extend into the channel 124 of the first diffuser 34. Then, the device housing 60 may further receive, at the other end of the device housing 60, one end of a second spline clip 58, such that the other end of the second spline clip 58 may extend into the channel 124 of the second diffuser 36. In this way, the device module 48 may be interposed between the diffusers 20 and coupled to each diffuser 20 using respective spline clips at each end of the device module 48.

[0048] In another embodiment, the spine clip 58 may extend entirely through a joining slot of the device module 48, such that a sufficient length of the spine clip 58 remains on each side of the device module 48 when the spine clip 58 is coupled to the device housing 60. Then, one end of the spine clip 58 may be coupled to the first diffuser 34, while the other, opposite end of the spine clip 58 may be coupled to the second diffuser 36. Indeed, one spine clip 58 may extend into corresponding channels 124 and 126 of the first diffuser 34. the device module 48, and the second diffuser 36 to couple the first diffuser 34, the device module 48, and the second diffuser 36 to one another. It should be understood that additional spline clips 58 (e.g., third and fourth spline clips), although not show n in FIG. 4, may be utilized along the side of the integrated diffuser assembly 50 facing away from the illustrated perspective view.

[0049] In yet another embodiment, the spline clip 58 may be a fixture (e.g., integrated component) of the device housing 60. That is, the device housing 60 may include spine clip 58 or other attachment features built-in on one or more ends of the device housing 60, such that the device module 48 may be coupled to one or more diffusers 20 without using additional spine clips. In this way, the device module 48 may additionally function as a connecting module configured to adjoin the first diffuser 34 and the second diffuser 36.

[0050] Keeping this in mind, the device module 48 may be interposed between the diffusers 22 to secure the device housing 60 in place and to maintain proper alignment between the diffusers 20. In other embodiments, the device module 48 may be attached to one end of the first diffuser 22 without coupling to the second diffuser 36, or vice versa. In still further embodiments, the device module 48 may be coupled to one or more additional device modules 48, such that multiple device modules 48 may be interposed between the first diffuser 34 and the second diffuser 36. In any case, the device module 48 may be concealed in the ceiling 46, situated within the integrated diffuser assembly 50 and above the encased opening 44. Indeed,the device module 48 may be generally hidden from view of an occupant of the room 30, which may provide a desired ambience or architectural quality of the room 30.

[0051] In some embodiments, the diffusers 20 and the opening 44 may include other, nonlinear shapes. For example, the diffusers 20 may be shaped to follow a curved (e.g., bending, undulating, curling, spiraling, etc.) path along the ceiling 46 to create an aesthetic effect. Additionally, some diffusers 20 may be a comer piece (e.g., a mitered comer) or a cross piece having segments of the main body 52 extending in cross-wise directions. In this way, the diffuser 20 may connect additional diffusers 20 at a comer or an intersection of an air flow path defined by the diffusers 20.

[0052] FIG. 5 is a bottom view of an embodiment of the integrated diffuser assembly 50, illustrating the device module 48 integrated with the first diffuser 34 and the second diffuser 36. In the illustrated embodiment, the device module 48 is a lighting module 70. It should be appreciated that, in other embodiments, the device module 48 may additionally or alternatively include other integrated devices 61, such as a speaker, a sensor, a camera, a network connectivity device (e.g., router), a sprinkler, or other suitable device. For example, the device module 48 may include a speaker configured to project sound from the opening 44 into the conditioned space. Additionally or alternatively, the device module 48 may include a camera configured to collect image data of (e.g., photograph or record) at least a portion of the conditioned space from within the opening 44.

[0053] As discussed above, the diffuser 20 may extend within or along the opening 44 in the celling 46, such that the opening 44 may facilitate air flow from the ductwork 14 and a conditioned space (e.g., the room 30) or between a plenum space and the conditioned space. In an installed configuration of the integrated diffuser assembly 50, the lighting module 70 may be recessed within the opening 44, such that the lighting module 70 does not visibly protrude from the ceiling 46. As discussed above, the border flanges 56 of the diffusers 20 encase the opening 44 and may abut the ceiling 46 about the opening 44 (e g., rest flush against the underside of the ceiling 46). In some embodiments, the border flanges 56 may be secured or fastened to the ceiling 46. The main body 52 of the diffusers 20 may be disposed above the ceiling 46 and may be generally hidden from view by occupants 42 within the room 30. In some embodiments, the lighting module 70 or other device module 48 may similarly include flanges 72 that are aligned with the border flanges 56 of the diffusers 20 to cooperatively define a border (e.g., continuous border, seamless border) of the integrated diffuser assembly 50.

[0054] A lighting element 74 (e.g., light output device) disposed within the lighting module 70 may output light through the opening 44 to illuminate the conditioned space (e.g., the room 30). The lighting element 74 may include one or more light-emitting diodes (LED), halogen lamps, florescent light bulbs, neon lights, incandescent light bulbs, image projectors, holographic projectors, or other suitable lighting elements. As illustrated, the lighting element 74 is configured to emit light directly out of the opening 44. In other embodiments, the lighting element 74 may provide indirect lighting by directing the light at a different angle, such as into the opening 44, and the emitted light may reflect, scatter, or otherwise redirect into the environment.

[0055] FIG. 6 is a schematic side view of an embodiment of the lighting module 70, taken along line 6-6 of FIG. 4, which may be an integrated component of the integrated diffuser assembly 50. That is, the lighting module 70 is an example of the device module 48 that may be incorporated with the integrated diffuser assembly 50. As similarly discussed above, the lighting module 70 includes the lighting element 74 (e.g.. LED, florescent light bulb, halogen lamp, neon light, optical projector, etc.) situated within a lighting device housing 80. As discussed above regarding the device housing 60 for the device module 48, the lighting device housing 80 may formed from extruded material, such as metal, polymer, or other suitable material. In some embodiments, the lighting device housing 80 may include ajoining slot 82 or other joining structure (e.g., boss pattern, extrusion, hook, etc.) to facilitate the attachment of one or more spline clips 58 or other connects configured to couple the lighting module 70 to the diffuser 20. In this way, the lighting module 70 may be coupled (e.g., in alignment) with the diffusers 20 as an integrated component of the integrated diffuser assembly 50.

[0056] As shown, the lighting module 70 may include a lens 84 configured to diffuse, filter, or otherwise modify light emitted by the lighting element 74. In an embodiment, the lens 84 may be a translucent (e.g., plastic) cover having a texture or shape that diffuses the emitted light to provide a desired effect, such as a softer appearance and / or more evenly distributed lighting to the environment. Alternatively, the lens 84 may focus the light toward a concentrated point, such as a spotlight. Another embodiment of the lighting module 70 may include a reflector in addition to or instead of the lens 84. The reflector may reflect the emitted light in one or more desired directions to suit or provide an environmental aesthetic. The material of the lens 84 or the reflector may be plastic, glass, metal, or other suitable material.

[0057] The lighting module 70 may further include the driver component 62 configured to regulate power to or otherwise control the lighting module 70 (e.g.. to control operation of the lighting element 74). For example, the driver component 62 may receive a power from a power source, such as via a cable 86. In some embodiments, the driver component 62 may be configured to receive control signals or instructions (e.g., from a control system), and the driver component 62 may operate the lighting element 74 based on the control signals. For example, the driver component 62 may include processing circuitry or other circuitry configured to control operation of the lighting element 74.

[0058] The lighting device housing 80 may include a metallic material, which may function as a heat sink for the driver component 62. In other words, heat generated by the driver component 62 may be dissipated via the lighting device housing 80. The power source may be a wall outlet, utility grid, a battery', a generator, a solar panel, or other suitable source of electrical power. The driver component 62 may transform (e.g., rectify) received power into power suitable for use by the lighting element 74. As mentioned above, the lighting module 70 may be configured to utilize low voltage power, which may enable installation via a general technician, such as an HVAC contractor.

[0059] The lighting module 70 may include or be a component of a light control system configured to receive instructions and perform operations to activate or modify the characteristics of the light output by the lighting element 74. The light control system may include a light controller having a memory' and processing circuitry. The light controller may be disposed within the lighting module 70 (e.g., within the driver component 62), or the light controller may be disposed outside and communicatively coupled with the lighting module 70. The processing circuitry may include one or more microprocessors, which may execute software (e.g., executable instructions, code) for controlling components of the light control system. The processing circuitry may include multiple microprocessors, one or more “general- purpose” microprocessors, one or more special-purpose microprocessors, and / or one or more application specific integrated circuits (ASICS), or some combination thereof. For example, the processing circuitry may include one or more reduced instruction set (RISC) processors.

[0060] The lighting module 70 (e.g.. the driver component 62) may also include a memory (e.g., a memory device), which may store information, such as instructions, control software, look up tables, configuration data, code, etc. The memory may include a volatile memory, such as random access memory' (RAM), and / or a nonvolatile memory', such as read-onlymemory' (ROM). The memory may store a variety' of information and may be used for various purposes. For example, the memory may store processor-executable instructions including firmware or software for the processing circuitry to execute, such as instructions for controlling components of the light control system. In some embodiments, the memory is a tangible, non- transitory , machine-readable medium that may store machine-readable instructions for the processing circuitry to execute. The memory may include ROM. flash memory, a hard drive, or any other suitable optical, magnetic, or solid-state storage medium, or a combination thereof. The memory' may store data, instructions, and any other suitable information. In some embodiments, the memory' may store instructions to enable control of the lighting module 70, such as adjusting an intensity' of light emitted by the lighting element 74 based on instructions, data, or feedback received by the light controller. For example, the light controller may receive user inputs via a user control device (e.g., control device 14, infrared transmitter, Bluetooth, Wi-Fi) to change one or more parameters of the light, such as intensity7, color, color change pattern. In an embodiment, the controller may enable a music-synchronization mode, wherein behavior of the light is correlated with music. It should be noted that the light controller may be a dedicated controller of the lighting module 70, or the light controller may control multiple lighting devices including other lighting modules 70 and traditional lighting devices.

[0061] FIG. 7 is a schematic cross-sectional side view of an embodiment of the integrated diffuser assembly 50. In the illustrated embodiment, the integrated diffuser assembly 50 is a ceiling-mounted assembly including a plaque diffuser 90 and an embodiment of the device module 48 (e.g., the lighting module 70). The plaque diffuser 90 may include a plaque 92 which is shaped and oriented to alter an air flow through the plaque diffuser 90. For example, whereupon the plaque diffuser 90 receives the air flow from the ductwork 14. the air flow may impinge against the plaque 92, disperse the air flow as a diffused air flow having altered velocity and pressure properties, and laterally discharge the air flow in various directions from sides (e.g., side outlets 94) of the plaque diffuser 90 into the environment. In the illustrated embodiment, the plaque 92 is square-shaped. In other embodiments, the plaque 92 may be a different shape, such as a circle. The plaque diffuser 90 may further include a back pan 96 coupled (e.g., mounted) to the ceiling. The plaque 92 may be coupled to the back pan 96, such that the plaque 92 and the back pan 96 are spaced apart, forming the side outlets 94.

[0062] In one embodiment, one or more lighting modules 70 (e.g., lighting elements) may be coupled to a ceiling-facing side 98 of the plaque 92, such that light generated by the one ormore lighting modules 70 is directed toward the back pan 96. The back pan 96 may then reflect the light toward the environment (e.g., room 30) having the plaque diffuser 90 (e.g., via the side outlets 94). In this way, the lighting modules 70 may illuminate the environment via indirect lighting. In another embodiment, the one or more lighting elements 74 may be coupled to a room-facing side 100 of the plaque 92 and / or may be coupled to the back pan 96 and may direct light through an opening (e.g., side outlets 94) of the plaque diffuser 90. In such embodiments, the lighting modules 70 may supply direct lighting to the environment. The lighting modules 70 may be mounted on a surface of the plaque diffuser 90, such as the plaque 92, the back pan 96, or another suitable surface, using any suitable technique, such as adhesives or mechanical fasteners. In other embodiments, the plaque diffuser 90 may be include additional or alternative embodiments of the device module 48, such as an audio speaker, a WiFi router or access point, a camera, and so forth.

[0063] FIGS. 8 and 9 illustrate perspective and cross-sectional views, respectively, of an installation of an embodiment of the integrated diffuser assembly 50 in the ceiling 46. The diffuser 20 (e.g., first diffuser 34) includes the two framing members 120 through which an air flow from the ductwork 14 and / or the plenum enters the conditioned space. Each framing member 120 includes boss features, such as the channel 124. The diffuser 20 may include ceiling clips 130 having an insertable portion 132 and a flange portion 134. The insertable portion 132 may be inserted (e.g., slid) into the channel 124 of one frame member 120 to secure the ceiling clip 130 to the diffuser 20. The flange portion 134 may be positioned beneath a ceiling frame 136 and / or above a ceiling panel 138. The flange portion 134 may be fastened to the ceiling frame 136 and / or the ceiling panel 138 using a fastener 140. In this way, the ceiling clip 130 may couple the diffuser 20 to the ceiling 46. A top surface of the border flange 56 may abut a bottom surface of the ceiling 46 (e.g., ceiling panel 138). The border flange 56 may be relatively thin, such that the bottom of the diffuser 20 is essentially flush with the bottom of the ceiling 46.

[0064] The device module 48 may have a similar cross-sectional profile as the diffuser 20, including corresponding channels and border flanges aligning with the channel 124 and the border flanges 56 of the diffuser 20 to give the appearance of a continuous surface. Each corresponding channel of the device module 48 may be aligned with a channel 124 of the framing members 120. such that a diffuser clip 58 may extend partially into both channels to join the device module 48 to the diffuser 20.

[0065] FIG. 10 is a perspective view of an embodiment of the integrated diffuser assembly 50. The illustrated integrated diffuser assembly 50 is configured as a linear slot diffuser, although aspects of the present disclosure are also applicable to other types and configurations of diffusers. In the illustrated embodiment, the integrated diffuser assembly 50 includes a plenum housing 150 (e.g., plenum box) having an inlet 152 surrounded by a flange 154. The ductwork 14 may be configured to extend into, extend about, couple to. and / or otherwise be fluidly connected to the inlet 152. In some embodiments, an adapter may be disposed between the flange 154 and the ductwork 14, whereby the adapter facilitates a fluidic and / or sealed connection between the plenum housing 150 and the ductwork 14. As such, the ductwork 14 may direct a conditioned air flow (e.g., a cooled air flow, a heated air flow, a dehumidified air flow) that may be generated by the HVAC system 32, for example, through the inlet 152 and into an interior volume of the plenum housing 150. The integrated diffuser assembly 50 may discharge the conditioned air flow received from the ductwork 14 via the diffuser 20 positioned beneath the plenum housing 150. Thus, the integrated diffuser assembly 50 establishes an air flow path from the ductwork 14, to the inlet 152, into the plenum housing 150, out through the diffuser 20. and into the conditioned space. A lower end 156 of the integrated diffuser assembly 50 may align with a lower surface of the ceiling 46. In this way, the lower end 156 of the integrated diffuser assembly 50 (e.g., border flanges 56) may be flush with the ceiling 46 or protrude minimally from the ceiling 46. The integrated diffuser assembly 50 may be supported by hanging clips 158 attached to the framing members 120. For example, the hanging clips 158 may include insertable portions 160 configured to be inserted into the channels 124 or the additional channels 128 of the framing members 120. Then strings, cables, and / or wires 160 attached to a support structure above the ceiling 46 may suspend the integrated diffuser assembly 50 from the hanging clips 158. In this manner, the integrated diffuser assembly 50 may facilitate distribution and / or dispersion of the conditioned air flow received from the duct 14 into the conditioned space.

[0066] FIG. 11 is a perspective view of an embodiment of the integrated diffuser assembly 50 having multiple device modules 48 coupled to the diffusers 20. Each device module 48 may have the boss features (e.g., corresponding channels) that may be aligned with the channels 124 of the diffusers 20, such that the spline clips 58 may connect an end of a diffuser to an end of a device module 48, as described in detail above. Additionally, the spline clips 58 may be used to join one device module 48 to another device module 48 in a similar fashion. For example, a first spline clip 58 may connect an end of the first diffuser 34 to a first end of a firstdevice module 48 via their corresponding channels 124 and 126. Additionally, a second spline clip 58 may connect a second end of the first device module 48 to a first end of a second device module 48 via their corresponding channels 124 and 126. Further, a third spline clip 58 may connect a second end of the second device module 48 to an end of the second diffuser 36 via their corresponding channels 124 and 126. In this way, multiple device modules 48 may be joined end-to-end using spline clips 58. Although two device modules 48 and two diffusers 20 are illustrated, it should be recognized that the diffuser assembly 50 may include any number of device modules 48 and diffusers 20 joined end-to-end in any order using the spline clips 58 inserted into the channels 124 and 126. The device modules 48 may have the same or different functions. For example, the first device module 48 may be a lighting module 70, and the second device module may be a speaker, an alarm, a sprinkler, a camera, a router, or another auxiliary electronic device.

[0067] As described in detail above, embodiments of the present disclosure are directed to an assembly that integrates a device module with one or more diffusers of an HVAC system. The diffusers may be mounted in a ceiling having an opening that connects the room to ductwork configured to deliver an air flow. The device module may be attached to the diffusers to form an integrated diffuser assembly, which may be disposed within an opening that exposes the diffusers and the device module to a conditioned space within the opening. In this way, the device module may be generally hidden from view by occupants of the conditioned space.

[0068] While only certain features and embodiments have been illustrated and described, many modifications and changes may occur to those skilled in the art, such as variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, such as temperatures and pressures, mounting arrangements, use of materials, colors, orientations, and so forth, without materially departing from the novel teachings and advantages of the subject matter recited in the claims.
