In addition, there are an air cleaning/ventilation device detachably installed in a window, used as a ventilation device, and used as an indoor air cleaning device.

An assembly type ventilation device for windows and doors is disclosed. The assembly type ventilation device for windows and doors comprises: a filter frame provided with an insertion part into which an air filter module is detachably inserted and fixed; a first fixing part installed on one side of the filter frame and fixed to a window; and a second fixing part installed on the other side of the filter frame and fixed to a window frame.

An architectural panel includes a mesh defining a plurality of openings and a plurality of flaps configured for attachment to the mesh within the plurality of openings, the flaps being movable to allow air flow through the openings.

An air purifier system characterized by a housing, a fan, and a motor, as well as a docking ring located at the outer edge of the inlet side of the air purifier system, a seat below the housing, a prefilter or barrier upstream of the fan, and a filter downstream of the fan. An air purifier system characterized by an upstream-to-downstream airflow path that includes an axial fan, a diffuser, and a filter, in that relative order, with an electric motor held along the centerline of the housing by one or more supports and/or guide vanes. A docking ring that facilitates attachment of a screen-like, mesh-like, cloth-like, or paper-like filter to a machine capable of air purification, characterized by having a large hole through which air passes and by attachment to the machine utilizing any tongue and groove system, for which installation and removal of the docking ring is achieved, in whole or in part, by rotation of said docking ring relative to the machine.

A ventilator door brings fresh outside air into a structure through an outside grill and a blower pulls outside air into a duct in the door and the air flows through the duct and into the structure through an inside grill remote from the outside grill. Heat is transferred from the flow of air to a heat sink disposed against the duct to cool the fresh air flowing into the duct. A regenerative heat sink may be used to capture heat from a flow of air from inside the structure and transfer the captured heat to a flow of outside air flowing into the structure. With the regenerative heat sink, a second blower is used to blow the inside air through the duct and outwardly through the outside grill before the outside air is pulled into the duct and blown past the regenerative heat sink to warm the air flow in to the structure. Several embodiments are included.

An improved double skin facade system for buildings is disclosed. In one embodiment, the double skin facade system is a multi-functional device that can be used in a variety of ways to provide heat, produce and store solar and wind electricity, take advantage of natural and biological properties of plants, and provide cooling and natural ventilation. In one embodiment, the device is comprised of a mounting structure, and multiple columns of interconnected modules. Through the interconnected movable modules, the double skin facade system can easily switch functionalities between a heater, ventilator and cooling system. The device is easy and inexpensive to operate and its functionalities can be changed with simple touches of buttons.

A recessed window assembly comprises a housing configured for recessed installation within a frame wall of a building adjacent a window opening and at least two sliding window components slidingly disposed within the housing such that the sliding window components are at least substantially disposed within the housing when in a non-deployed position and that fill the window opening when in a deployed position. The window components can comprise, for example, a transparent untinted window, a transparent tinted window, a translucent window, a window screen, a security plate, an electric fan, or an air filter.

A window structure is configured to form a principal chamber enclosing a first window pane installed in an exterior wall of a building. The window structure includes a first surface configured to absorb solar energy and a main frame including a second window pane. An axial hinge is configured to allow to the main frame to tilt between a first position and a second position. When the main frame is tilted in the first position, the first surface is positioned in a first orientation that allows the first surface to directly receive sunlight through the second window pane. When the main frame is tilted in the second position, the first surface is positioned in a second orientation in which the first surface is prevented from directly receiving sunlight through the second window pane. The window structure may be used for ventilating the structure and shading during the warm weather.

A device may include a first temperature/humidity sensor positioned on a room-side surface of the housing to sense a first temperature and a first relative humidity of ambient air within a room; a second temperature/humidity sensor within the cavity to sense a second temperature and a second relative humidity of air within the cavity; and a glass temperature sensor positioned on an internal surface the primary window to sense a third temperature of the glass. The device may include a first vent within the housing to allow the ambient air to draw in by a fan into the cavity. The device may include a second vent within the housing to allow the air within the cavity to pass to the room. A controller within the housing may read the first temperature, the first relative humidity, the second temperature, the second relative humidity, and the third temperature and activate the fan.

A construction thermoacoustic partition to isolate areas from external or internal environments, refrigeration, and vehicles. The partition consists of a frame with airtightly glued insulating panels, transparent or not. If glass pane, frame, and panels are glued, they create an airtight chamber where pressure, light and solar tracking sensors are located. In its internal perimeter it has photovoltaic cells and a blind whose sheets are photovoltaic cells that make it self-sufficient in energy. The profile of the frame has channels to circulate air, where electric resistance is located, which in winter raises the temperature of the panel edges, in another, fans, temperature sensors, micro-pump, wires and reinforcements are located. The horizontal planes that create these channels have coextruded thermoacoustic bridges. It has a microprocessor with automatic or digitally modified instructions, with voice and remotely, so that components act in real time, depending to changes in the environment, which can be with Artificial Intelligence.
