An air vent includes a housing, an air guide surface, an air flow adjusting element, and a vane. The air guide surface at least partially defines an air duct configured to convey a volumetric flow of air through the housing so that the volumetric flow of air exits the air duct in a direction that at least partially defines an air discharge direction perceived outside of the air vent. The air flow adjusting element is moveable to vertically change the perceived air discharge direction, and the vane is movable to horizontally change the perceived air discharge direction. The vane is not visible to a user of the air vent when the air vent is viewed from an air outlet end of the housing.

Provided are an air duct assembly and an integrated air conditioner, wherein, the air duct assembly includes a fixed shell and a rotating air duct body, a first air duct and a second air duct are formed in the rotating air duct body having a first position and a second position; when the rotating air duct body is in the first position, the indoor air inlet duct is connected with the indoor air outlet duct, the outdoor air inlet duct is connected with the outdoor air outlet duct, the indoor air inlet duct is disconnected from the outdoor air outlet duct and the outdoor air inlet duct; the indoor air outlet duct is disconnected from the outdoor air outlet duct and the outdoor air inlet duct; when in the second position, the indoor air inlet duct is connected with the first air duct and the outdoor air outlet duct to form a turbid wind exhaust duct, the indoor air outlet duct is connected with the second air duct and the outdoor air inlet duct to form a fresh air inlet duct, the turbid wind exhaust duct is separated from the fresh air inlet duct.

A house/building fresh air to air cross flow heat exchanger includes an inner elongate conduit disposed longitudinally within an outer elongate housing thereby defining a first air passageway through the inner conduit and a second air passageway between the inner conduit and the housing. A portion of the inner conduit is constructed with a sorption paper wall/assembly between the passageways. The sorption paper assembly is cylindrical shaped and includes a plurality of longitudinally extending folded pleats thereby increasing the surface area between the exhaust and incoming fresh air passageways. A cylindrical air permeable screen extends longitudinally through and radially supports the sorption paper wall/assembly. The passageways can be connected to a furnace duct using air scoops to thereby forcibly direct air through the passageways. Alternatively, a fan assembly is aligned with the passageways for forcibly directing air therethrough.

A device and corresponding method for ventilating a space is provided. The device includes an air conditioning system that is adapted for conditioning recirculated and/or fresh air to be used for the ventilation of the space. The device also includes at least one air treatment means adapted for exposing the recirculated and/or fresh air to one or more of UVC, ozone and/or atomized detergents. Relative to an air stream, the air treatment means is positioned prior to the air conditioning system receiving the recirculated and/or fresh air, and/or prior to the air conditioning system releasing the air into the space.

A building sheltering structure is configured to facilitate the shielding of domicile or building into an underground foundation before an emergency environmental condition arises. The foundation includes a cover plate and/or a second plate that translate horizontally to occlude the at least one domicile upon retraction into a secure cavity of the foundation by a lift assembly in the foundation cavity. The cover plate and second plate offer optimal protection to the domicile thereunder for various extreme conditions. Mounted atop the lift assembly, the at least one domicile can be fully retracted into the foundation cavity and completely shielded. The operation of the lift assembly is commanded and powered by a supply system, of which a processor facilitates emergency warnings and panic transmissions to signal for help. Further, a plurality of solar panels mounted atop the at least one domicile keeps the system charged for the use in emergency.
