Embodiments disclosed herein relate to air flow control blinds or tents useful for controlling scents emitted therefrom. The air flow control blinds can include walls, a roof, windows in the walls, and at least one directional vent disposed on the walls, where the at least one directional vent includes an inlet on the inner surface of the blind and an outlet fluidly connected to the inlet, the outlet facing downward on the outer surface of the blind to direct fluids flowing therethrough towards the ground. The air flow control blinds may include one or more roof vents adjacent to the walls on the roof. The air flow control blind includes at least one oxidant generator mount on one or more of the roof or the walls to mount an oxidant generator thereon. Blind systems can include a portable oxidant generator positioned in the blind.

The air flow control blinds may include one or more roof vents adjacent to the one or more walls on the roof to remove air from an interior of the blind therethrough. 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.

According to an aspect of the present disclosure, an air quality management system may include a mobile application distributed to at least one user device, at least one air quality management device, and at least one computing resource, wherein the at least one computing resource operates a first networking layer configured to receive input from the at least one mobile application. Also, the at least one computing resource operates a second networking layer that receives input from the at least one air quality management device. The air quality management system may further comprise a data connection between the first and second networking layers to transfer commands of the at least one mobile application from the first networking layer to the second networking layer, and to transfer device information of the at least one air quality management device from the second networking layer to the first networking layer.

A refrigeration cycle apparatus includes: a casing; an air handling unit accommodated in the casing and including a first duct and a first outlet, a second duct and a second outlet, a first fan and a second fan; and a refrigerant circuit configured to circulate refrigerant in the refrigerant circuit and including a first heat exchanger and a second heat exchanger.

An exhaust and filtration assembly includes: a housing; an exhaust vent configured to guide unfiltered air out of the exhaust and filtration assembly; a filter assembly configured to filter air and guide the filtered air out of the exhaust and filtration assembly; an exhaust assembly configured to direct raw air from an entry port of the exhaust and filtration assembly and direct air out of the exhaust vent without the air having been filtered; and a controller comprising computing logic configured to control so that only one of air filtration and raw air exhaust occurs at any given time.

Extremely lightweight device which hangs from the ceiling by 1 point (2 screws), used for absorbing/pulling in air, smoke and vapors and gets it out to the ceiling duct or window.

Made of 2 extensible sticks, having 1 point of support and 2 points of pushing on the ceiling. The hood (tip of the device) can be rotated/moved in the room 360 degrees, basically anywhere needed for the air extraction.

An exhaust vent cap assembly can be installed in a roof deck of a building to allow a one-time connection of the insulated duct to the roof from exhaust fans within the building.

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.

Disclosed is a method of operating an air purifier by executing an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a fifth generation (5G) environment connected for the Internet of Things. A method for operating an air purifier comprises determining whether an indoor situation is a situation in which protection of a filter is necessary based on sensor information from at least one sensor, in response to a determination that the indoor situation is the situation in which protection of the filter is necessary, suspending an air purifying function, and operating one or more ventilation devices. According to the present disclosure, it is possible to protect the air purifier from a situation in which a life of the filter of the air purifier can be drastically shortened.
