The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

In a roof window system, the housing (6) of the ventilation unit (5) is prepared for accommodation of a standard ventilator and/or a regenerator allowing an air current through a ventilation passage (28), from an exterior grating (18) to a ventilation panel (3) integrated into or in continuation of a lining panel of a room in the interior of the building in which the roof window is installed.

A portable air conditioner unit window installation system having a closure plate, a vent opening through the closure plate, a clamp fixture located adjacent to the vent opening in a longitudinal direction of the closure plate, and a clamp movably mounted to the clamp fixture.

A window air conditioner installation system comprising a top rail, a bottom rail, a first vertical rail configured to connect to the top rail and the bottom rail, and a second vertical rail configured to connect to the top rail and the bottom rail. A clamp fixture is connected to the top rail, and a clamp is movably mounted to the clamp fixture. The clamp is movable between a first clamp position in which a clamp face is a first distance from the top rail in a depth direction, a second clamp position in which the clamp face is a second distance from the top rail in the depth direction.

An air conditioner including: a housing communicating with a space in which a window covering is installed, and including a suction port through which air is suctioned from the space and a discharge port through which air is discharged into an indoor area; a heat exchanger configured to exchange heat with the air suctioned through the suction port; a blower fan allowing air to be suctioned through the suction port or allowing air to be discharged through the discharge port; and a guide panel provided at the suction port to guide the window covering to prevent the window covering from covering the suction port.

A clamp for securing an air conditioning unit in a window without the need for any modification and/or damage to the air conditioning unit or window. The clamp includes a plurality of planar members forming two oppositely facing channels. A first channel engages the air conditioning unit rail while a second channel engages the window sash of the window. The clamp further includes two fasteners to abut the window sash and the air conditioning unit rail. The clamp therefore prevents the window from being opened and the air conditioning unit from being pushed through the window.

An air conditioner includes an indoor unit, an outdoor unit, and an inductor assembly. The indoor unit includes an indoor air duct component. The outdoor unit includes an outdoor air duct component. The indoor air duct component and the outdoor air duct component are spaced apart. The inductor assembly is located between the indoor air duct component and the outdoor air duct component, and includes an inductor box shell, an inductor and an inductor box cover. The inductor box shell has an accommodating space and includes a shell side plate, a first heat dissipation opening, a first water blocking portion, a shell top plate and a second heat dissipation opening. The inductor is disposed in the accommodating space. The inductor box cover is disposed on top of the inductor box shell, and includes a cover top plate, a third heat dissipation opening and a second water blocking portion.

The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

An anti-tip bracket assembly for a window air conditioning unit is disclosed, and more particularly, an anti-tip bracket assembly that pertains to securing a window air conditioning unit within a window assembly while allowing a user to open and close the window assembly in a safe and convenient manner is disclosed.

A box which is expandable vertically and horizontally is disclosed. The box can be expanded both vertically and horizontally simultaneously, or in only one of these directions. This is accomplished by pulling/pushing opposite sides further/closer to each other. Rails which at least partially extend between respective opposite sides allow such an expansion/or contraction, the rails, in embodiments, having a pin of one section of the box held within a slot of an adjacent section of the box. The box, in embodiments, is made up of four separate pieces, each being one quadrant (top & left, top & right, bottom & left, bottom & right) of the box. Such a box can be expanded/collapsed to fit within a window and hold an air conditioner there-in.
