A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.

The exhaust vent cover produces a few purposes: The exhausting of air, heat, dust, lint, fumes and other unwanted elements from the dwelling's interior to the dwelling's exterior. 1) Provides a mechanical way of preventing outside air, dirt etc. from entering the interior space/area by utilizing a mechanical flap that swings outward by air pressure, electrical motor or pneumatic control hooked to an on/off control switch. 2) Prevents birds, rodents and other small critters from entering the interior space/area. This exhaust cover is designed in three (3) parts: First part: is a molded plastic or metal hood cover with slots on sides. Second part: is an attachable frame with metal spikes surrounding the opening of the hood cover. Third part: a backdraft cover that opens outward can be made of metal or plastic, this cover which attaches with a hinge like mechanism at the top inside opening of the exhaust vent cover.

A process of fabricating a static structure including an interior volume that includes the steps of mixing coal combustible residual (CCR) with structural reinforcing materials to form a construction material and utilizing the construction material to fabricate exterior enclosure-forming components of the static structure. The enclosure-forming components are sufficiently reinforced, enhanced and/or thick to provide protection against exterior forces directed against the structure.

Smoke is removed from a building interior by a system in which a controller is activated upon a signal from any of one or more smoke detectors connected thereto. A conduit, with an air-receiving end located in the building and an air-exhaust end located outside the building, has an associated air mover arranged to exhaust air from the building through the conduit. A first and second valve in the conduit are normally closed, preventing air flow. On a smoke detection signal from the controller, the first valve and second valve open, the air mover actuates and air/smoke is withdrawn from the building until a “reset” signal is received. On reset, the air mover shuts down and the first and second valves close. The air-receiving end is preferably directly connected through a forced-air HVAC system of the building to avail use of its ducts and air movers.

A wall exhaust vent (e.g., for a dryer or other HVAC system) can include a housing defining a vent opening, and one or more bumpers on or at least partially within the housing and configured contact a door of the wall exhaust vent in a closed position. The one or more bumpers can include a bumper body, and a magnet disposed at least partially within the bumper body that is configured to magnetically interact with the door of the wall exhaust vent to bias the door to the closed position.

A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.

A common vent application and an independent fan coil are disclosed for improved heating, cooling and water making in a building. The independent fan coil obviates the common boilers and chillers in addition to all the common heating and cooling distribution piping used in known systems. Instead, the fan coils contain all the hydronic heating components and all the components needed to provide AC without the use of common boilers and chilled water systems. The fan coils utilize common vent shaft ducting to exhaust the products of combustion generated for the independent tankless water heater. In addition, the common vent shaft may utilize a negative static pressure environment to exhaust the heat of rejection from the AC portion of the fan coil unit.

A ventilated enclosure includes a vortex baffle to harness the turbulence of air in a way that uses less exhaust air while still providing ample protection to the user. The vortex ventilation system uses the total interior shape and proportion of the ventilated enclosure to direct the motion of air flow in a manner that improves efficiency. The vortex ventilation baffle can enhance the way air naturally curls, or rolls, as air flows through the enclosure. The vortex baffle can cause a mono-stable vortex to from in the enclosure. This vortex is resilient to disturbances that cause ventilated enclosures, such as chemical fume hoods, to spill. The stable vortex is above the work surface and less affected by the way apparatus is loaded inside the enclosure. The vortex baffle achieves better containment (improved safety) at lower exhaust flow (improved energy consumption) as compared to conventional ventilated enclosures.

A valved cover is described for controlling air flow through perforated-strip-type soffit vents surrounding houses. The narrow, continuous vents are completely enclosed except for valved portholes in the cover, the flap valves being stiffly hinged to stay open (and quiet) in most weather to allow two-way ventilating air flow between outdoors and attic/roof space. The valved covers “harness” very strong winds: those on the the windward have their valves blown closed, blocking potentially destructive wind/rain entry into the attic/roof space, while those facing lee sides remain open so that the attic/roofspace is connected only to the wind-depressurized lee-side air and is therefore itself depressurized, helping hold the roof envelope together. The valved covers can be factory-mounted on the soffit panels and flat-folded for compact shipping and handling.

A novel and versatile vertical ventilation diffuser system to reduce transmission of airborne particles provides an harmful airborne particle nearly free indoor environment for one or multiple person to breathe, and to isolate and protect the personal space of a person by means of reducing the horizontal flow of air inside an enclosed space and transporting any possible harmful airborne particles, such as viruses, by means of a top down air flow. Thereby, a continuously clean environment is maintained by generating an air curtain around each person by means of a vertical ventilation diffuser system, which may be custom designed and sized for multiple types of suspended ceilings, or in standard sizes, with particular application in office, school, restaurant or concert hall settings. The versatile vertical ventilation diffuser system may further be implemented in a matrix configuration to promote the use of multiple users in a single indoor space.
