The present disclosure relates to air filters. More particularly, it relates to adjustably sized air filter systems capable of use in a window opening. Some embodiments relate to a filter media assembly configured in a roll. In some embodiments, the filter media assembly includes a filter media having a leading end opposite a trailing end and first and second opposed side edges extending between the leading end and the trailing end.

The present disclosure generally relates to adjustably sized air filter systems capable of use in a window opening. The present disclosure also related to methods of making and using these adjustably sized air filter systems.

The present disclosure relates to powered window air filters. More particularly, it relates to air filter systems capable of use in a window opening. Some embodiments relate to an adjustably sized air filter. Some embodiments include a filter assembly including filter media and a fan and/or control unit that forces air through the filter media in the filter assembly.

The present disclosure relates to air filters. More particularly, it relates to adjustably sized air filter systems useable in window opening. Some exemplary window air filter assemblies include two u-shaped frame members that can be coupled to form an adjustable frame assembly; and a filter media assembly that is attachable to the frame assembly and that includes an adjustable length media. The window filter assemblies are capable of moving between a collapsed state to an expanded state.

The Green Energy Smart Window of Wireless Window 5R System W5RS is constituted of the Multimedia panel, the Electrochromic panel and the transparent Solar panel, etc. The Green Energy Smart Window harvests solar energy with transparent solar panel to be electric energy to provide power to smart Multimedia panel and smart Electrochromic panel, etc. W5RS is the Green Energy Smart Window of the next generation smart home standard. W5 represents Wireless Wireline Weave Wishful Window. 5R represents Recycling Resonant Resynchronization Rectifying Regulator. The novel 5R can have the AC/DC power efficiency 95% which is the highest for the wireless power supply standards. 5S represents Smart Solar Supply Silicon System. W5RS is the killer application and 5R is the killer core technology. To integrate the W5RS technology to be the Green Energy Smart Window, the W5RS adopts the 23Less Green Technology. The 23Less Green Technology are the Noiseless Field System On Chip FSOC, Curtainless Window, Bladeless Turbofan, Brakeless Vehicle, Sawless LNA, Resistorless, Capless, Inductorless, Diodeless Random Number Generator, Xtaless Clock Generator, Clockless Switch Mode Power Supply, Ground-Bounceless I/O, Switch Lossless Rectifier, Power-Lossless PA, Rippleless and EMI-Less Battery Charger, Overshootless and Rippleless LDO.

Provided is an intake-exhaust unit that easily controls the flow of air in an intermediate cavity of a double skin structure window glass, and a double skin system using the same. The intake-exhaust unit is comprised of: a first distribution port of passage of the air; a second distribution port of passage of the air, the second distribution port being separated from the first distribution port; a third distribution port of passage of the air, the third distribution port being separated from the first distribution port and the second distribution port; a fan for sending out the sucked air; a negative-pressure passage provided on the air-sucking side of the fan, the negative-pressure passage having intake holes that communicates with the first, the second, and the third distribution ports; and a positive-pressure passage provided on the air exhausting side of the fan, the positive-pressure passage having an exhaust hole that communicates with the first, the second, and the third distribution ports, wherein the air is sucked from any of the first, the second, and the third distribution ports; and the air is exhausted from any of the distribution port other than the port in use for sucking the air among the first, the second, and the third distribution ports.

A supply air apparatus for producing outdoor air into an indoor space assisted by an auxiliary powered blower by simultaneously mixing the outdoor air with air from the indoor space. In connection with an outdoor air flow way in a structure in a building between the indoor space and outside air, a flow space and flow connections for outdoor and indoor air for mixing with each other, the blower and a blow flow arrangement for leading a mixed flow of air into the indoor space in the building. In connection with a supply air device in an outer wall of the building, an air distribution device including: a frame; a flow space in the frame; an inflow outdoor and indoor air that joins with the flow space and opens into an internal space in the building; the blower; and a blow flow leading the mixed air into the indoor space.

A door sealing system includes a door seal for sealing either an upper or a lower side of a building door wing, and an air channel which enables, when the door seal is in the sealing position, air to circulate from a longitudinal side of the door seal to an opposite longitudinal side of the door seal. The door sealing system also includes at least one ventilator that guides air through the air channel. The door sealing system enables sufficient air to be exchanged even when the door wing is closed.

A modular rail component is described, e.g., as a modular rail accessory (MRA) that is configured to enclose a plurality of modular components, with the MRA structurally constituting one of: a bottom rail or a top rail of the modular door system.
