A safety system implemented within a structure includes a source of breathable air, and a fixed piping system to supply the breathable air from the source to each interior region of a number of interior regions across the structure. The fixed piping system is implemented in a ringed architecture including a first portion of the fixed piping system proximate the each interior region and a second portion thereof farther away from the each interior region. In accordance with the ringed architecture, the first portion and the second portion are implemented as a continuous ring with respect to the source of the breathable air such that, even during a compromise of a first sub-portion of the first portion, unaffected by the compromise, the breathable air continues to be supplied to a second sub-portion of the first portion by way of the second portion.

Examples of the present disclosure include an enclosure. The enclosure includes a floor. The floor includes a first surface, a second surface opposite the first surface, and floor apertures. The enclosure includes a ceiling having ceiling apertures. The enclosure includes interior walls extending, along a length of the interior walls, from the ceiling to at least the floor. The enclosure includes an exterior wall. The exterior wall includes a first portion extending from at least the ceiling of the enclosure to at least the first surface, a second portion extending below the first surface at least one exterior wall aperture. The at least one exterior wall aperture extends through a thickness of the exterior wall and is located no more than a distance, from at least one of the first surface and the second surface of the floor, equal to twenty percent of a total length of the exterior wall.

An under-floor HVAC system for a building includes a pliable air duct lying upon a subfloor. A matrix of pedestals resting upon and extending upward from the subfloor supports a set of floor panels, which thus creates a plenum between the subfloor and the set of floor panels. The air duct extends through the plenum to convey conditioned air from a supply air duct to a series of registers in the floor panels. The registers disperse the conditioned air to a room or area just above the panels. To help keep the air duct from repeatedly extending, retracting, and otherwise sliding freely along the subfloor in response to changes in air duct pressure, the air duct is held taut by anchoring a distal downstream end of the duct to one or more of the floor-supporting pedestals. Various air duct configurations can be assembled from a predefined assortment of duct components.

Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.

Provided are a system of highly clean rooms capable of continuously maintaining high cleanliness of air of class 1 or above and supplying enough oxygen inside the room for several persons to live in and a wall adapted to the structure of such a system. The system of highly clean rooms 10 is provided with a living space 6 and a space 5 between the roof and the ceiling as subspaces of an enclosed space formed by a room 1a. One of the lateral walls of the room 1a is constituted of a wall 9 with an internal space 7, which is a hollow wall. The internal space 7 and the living space 6 are in contact via an inner wall 9a of the wall 9, and a gas exchange membrane 26 is stretched in the inner wall 9a. Furthermore, a gas flow path 24 is provided inside the inner space 7 and the gas flow path 24 allows airtight communication between an opening 23 provided on the lowest part of the internal wall 9a and a gas entry opening of a fan filter unit 21 provided on a ceiling wall 2a inside the space 5 between the roof and the ceiling.

The present disclosure relates to air conditioning systems and methods. An aspect of the present disclosure is a device that includes a housing having an external surface and defining an interior volume, a heat exchanger positioned within the interior volume, a fluid line partially positioned within the interior volume, a sleeve extending from the external surface and terminating at a distal end of the sleeve, and a fluid connector. The sleeve has an outside wall spanning a length of the sleeve and defining an internal cavity, the fluid connector is positioned at or near the distal end, a portion of the fluid line is positioned within the internal cavity, and the fluid line provides a fluid connection between the heat exchanger and the fluid connector.

An air conditioning module including a thermo electric cell having a first side and a second side; an conditioning duct attached to the first side of the thermo electric cell; and an exhaust duct attached to the second side of the thermoelectric cell; wherein the conditioning duct receives and conditions air from a room, and the exhaust duct vents unwanted thermal energy.

A disclosed air control system includes a tent having at least one air flow compartment integrated with the tent fabric and configured to define openings in the tent fabric for an air flow interior to the tent. The disclosure also includes at least one flexible tubing having a releasable attachment on a first end to an external air control unit and a releasable attachment on a second end to a complementary attachment integrated on an outside wall of the tent. The disclosure additionally includes at least one releasable attachment for an air inlet hose integrated with the tent fabric and in communication with the at least one air flow compartment. The disclosure further includes at least one releasable closure for the at least one releasable attachment, the at least one releasable closure configured to seal the tent wall in the absence of an air pressure.

A bracket that is mounted in a wall or ceiling, and cooperates with an insert that can be adjusted flush with the wall or ceiling surface. Slots in the flange, and dimples in the insert facilitate the flush adjustment.
