The air flow control blind includes at least one oxidant generator mount on one or more of the roof or the one or more walls to mount an oxidant generator thereon. Blind systems include a portable oxidant generator positioned in the blind. The blinds and blind systems are used to control scents therein or therearound.

A lightweight thermal barrier panel and anchor assembly for installation on a new or existing building envelope is disclosed. The system includes a modular panel with an infill barrier and structural anchors. The anchors are attached to the new or existing building envelope on at least one side of the building envelope to receive the thermal barrier panel to create an air cavity between the panel and the building envelope. The thermal barrier panel framing includes openings within rigid framing members to promote ventilation of the air cavity to the at least one side of the thermal barrier panel.

There is provided a wall port cover to be installed in building wall ports. Wall ports are simply openings in a wall or ceiling of a building which may be used to house electrical panels, HVAC systems, access panels, lighting switches, and the like. The wall port cover comprises an engagement means which is rotatable between an engaging position and a releasing position. In the engaging position, the engaging means extend beyond the wall port cover to engage a top surface of the wall or ceiling drywall panel to support and retain the wall port cover within the vent opening. In the releasing position, the engaging means are retracted within the wall port cover to disengage from the top surface of the wall or ceiling drywall panel to allow the wall port cover to be removed from the vent openings.

A method of installing a dryer vent in a building exterior foundation wall during construction of the building. The dryer vent installation method comprises mounting a rigid wall plate that includes a fastener tube, the fastener tube includes outwardly facing pins. The dryer vent installation method includes mounting a removable flapper housing with mounting slots, the housing including a flapper valve. The dryer vent installation method further includes removably fastening the flapper valve housing slots to the fastener tube pins.

Apparatus and method for ventilating a building structure, such as a residence. In some embodiments, a ventilation system includes a damper assembly which extends through an interior substrate (e.g., an interior wall) of the structure and an exhaust assembly which extends through an exterior substrate (e.g., an exterior wall of the structure and which is in communication with the damper assembly via a control circuit. The interior wall separates a conditioned space and an unconditioned space. The exhaust assembly is initially activated to vent exhaust air from the unconditioned space while a door of the damper assembly remains closed. The door is subsequently opened responsive to a measured environmental parameter, such as a differential pressure between the conditioned and unconditioned spaces, to generate a combined airflow that passes from the conditioned space to the unconditioned space and then to the exterior of the structure.

A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, and a water pump. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser. The primary condenser receives the flow of refrigerant and outputs the flow of refrigerant at a lower temperature through heat transfer with a flow of fluid. The flow of fluid is directed, by the water pump, to a heat exchanger or an external source, where heat is rejected from the flow of fluid.

A method for building a soundproof enclosure (10) in the form of an independent structure with acoustic properties for isolating noise and vibration is disclosed. The soundproof enclosure (10) comprised a plurality of acoustical wall panels (12) interconnectable each to another at opposing sides for enclosing an interior space (41) of various sizes. The soundproof enclosure (10) further comprised one or more modular multilayer ceiling unit(s) (13) assembled onto the top edges of the acoustical wall panels (12) to form the enclosure. The ceiling unit (13) comprised a plurality of ceiling layers (17), each ceiling layer (17) being vertically spaced apart with one another by brackets to topographically form the multiple guided spaces necessary for air flow circulation within the enclosure (10). These guided spaces can also house multiple implements such as circulation fan, air filter and sound silencer. Sound insulating material layer(s) are interposed between the contacting surfaces of the ceiling unit (13) and the acoustical wall panels (12) and/or all around the surfaces to isolate and decouple the ceiling unit (13) from the acoustical wall panels (12) from vibrations. A sound barrier cover (16a or 79) is interposed at the openings (25) of the air passages (24) to further reduce the sound level emitted into and exiting from the enclosure. In addition, a construction method by elevating the heavy acoustical wall panels (12) and the ceiling units (13) until they fall into precise assembly location for ease of assembly of the components of the enclosure (10) and a floor base unit 11 that enabled the enclosure (10) to about easily in whole is also disclosed. Furthermore, a method to ease assembly of the enclosure (10) by use of removable heavy-duty handles (87) is disclosed.

A vent assembly is configured to be mounted proximate to an air-flow portal defined by a surface of a wall of a building; this is done in such a way that the vent assembly presents outer surfaces that are exposable to exterior weather elements after the vent assembly is mounted proximate to the air-flow portal. An envelope assembly is configured to surround the outer surfaces of the vent assembly after the vent assembly is mounted proximate to the air-flow portal. The envelope assembly is positioned proximate to the vent assembly. The envelope assembly is configured to protect, at least in part, the outer surfaces of the vent assembly from undesirable exposure to the exterior weather elements.

A clothes dryer exhaust vent (dryer vent) and the method of installation in a residential or commercial building exterior foundation wall, during construction of a building, to save the expense and costs of a clothes dryer exhaust vent installation after a building has been constructed, to reduce repair and additional construction costs. The dryer vent has a rigid wall mounting plate (plastic or metal) that is mounted in the construction block array of an exterior building foundation wall while the wall is under construction. The clothes dryer exhaust vent includes a clothes dryer exhaust vent tube connected through the rigid, wall mounting plate (manually removable), an exterior (outdoors) hemispherical-shaped clothes dryer vent open end cover assembly, manually removable for cleaning and removing lint, said cover assembly including a clothes dryer exhaust vent flapper valve.
