A device for treating the air in a confined space has a first module and a second module that are telescopically coupled, in such a way that the two modules can slide one respect to the other in order to adjust to a different thickness of a wall that separates the inside from the outside. The device has a heat exchanger disposed in the first module, a first fan disposed in the first module downstream a filter to extract air from the outside to the inside, and a second fan disposed in the second module to extract air from the inside to the outside. The device also has a radon detector connected to a control unit that controls the two fans.

The apparatus and method disclosed herein is a new system that can be used as windows air conditioner's accessary and its possible embodiments.

By first attaching base modules to the window air conditioner's housing and/or window frames, it can create an foundation with opening for attaching other functional modules. The functional modules attached on later are interchangeable and allow a variety of applications and combination of applications.

The invention also makes installing and remove window AC unit more safer and easier.

The invention had built a new ecosystem around the window air conditioner unit. It turns the current wasted spaces around windows AC housing into a unique area where users can design and customize for different functional uses. Because the functional modules are interchangeable, user can switch easily between different modules and designs with different possible combination from time to time to achieve different goals and meet different needs.

A modular return air plenum for HVAC systems is provided that can be used to support a base an air handler unit or furnace in an HVAC system. The modular return air plenum is customizable in its width due to the use of one or more corner pieces, that when coupled together, form a connected return air plenum that is modular and adjustable in size. The modular return air plenum may include additional modular pieces that are integrated between the corner pieces. More than one modular return air plenum can be formed together and then stacked onto each other in order to increase a height of the combined modular return air plenum and provide for a taller modular return air plenum to best suit the support base needed for an air handler unit or furnace in the HVAC system.

Embodiments of the present disclosure are directed to collapsible hood for a heating and cooling system that includes a plurality of panels configured to couple to a housing of the heating and cooling system, wherein the plurality of panels is configured to be translated between a collapsed position and an open position, wherein the plurality of panels is substantially flush against the housing in the collapsed position to configure the heating and cooling system for transportation, and wherein the plurality of panels are configured to extend from the housing to protect openings in an air intake of the housing and to allow passage of air through the air intake in the open position.

A heater assembly for a heating, ventilation, and/or air conditioning (HVAC) system has a heater and a controller enclosure. The heater has a plurality of heating elements in a frame that has two opposing ends. The controller enclosure has two end walls and a plurality of side walls in a non-rectangular polygonal configuration. One of the two opposing ends of the frame is coupled to one of the two end walls such that an orientation of the heating elements may be changed based on respective locations of the plurality of side walls of the controller enclosure.

The present technology is generally directed to appliance hubs and related systems and methods. In some embodiments, an appliance hub includes a frame assembly and one or more panel assemblies mounted thereto. Individual panels of the panel assemblies can be removably coupled to the frame. At least some of the panels can include one or more functional components, such as one lighting elements, acoustic controls, speakers, vents, mechanical/electrical/plumbing (“MEP”) components, and/or other devices. Accordingly, the frame assembly can be used to manufacture many differently configured appliance hubs with different arrangements of panels and devices positioned thereon. Further, the ability to remove or partially remove individual panels of the appliance hubs after the appliance hub is installed in a ceiling or other upper portion of a room allows for maintenance of existing devices of the appliance hub and/or replacement of devices or the panels themselves.

An air cleaning device is provided including a unit base, at least one support member coupled to the unit base, and a plurality of panels mounted to the at least one support member. At least one of the plurality of panels includes a filtering substrate. The air cleaning device is transformable between a retracted configuration and a deployed configuration. In the deployed configuration, the plurality of panels are separated from one another to define a plurality of flow channels.
