An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

An air purifying system includes a robot cleaner configured to generate map information during vacuum cleaning and at least one air purifier that is operated based on the generated map information. Air purifying is performed using updated map information acquired by the robot cleaner during cleaning. The at least one air purifier includes two portable air purifiers mounted on a base air purifier. The two portable air purifiers are configured to be lifted from the base air purifier and moved to separate indoor rooms. The base air purifier includes a controller that determines, based on the generated map information and other information, which rooms the two portable air purifiers should be placed in so that air purifying may be efficient.

An electric component mounting unit for an air-conditioned garment, which is used in combination with a garment body having a fan opening and which is mounted on a body, includes a fan which takes air from outside into the garment body, a mounter which mounts the fan on the body, and a fan attacher which attaches the fan to the mounter. The fan includes a fan-side linker which links the fan with the fan opening.

Embodiments of the present disclosure are directed to collapsible hood for a heating and cooling system that includes a plurality of panels configured to couple to a housing of the heating and cooling system, wherein the plurality of panels is configured to be translated between a collapsed position and an open position, wherein the plurality of panels is substantially flush against the housing in the collapsed position to configure the heating and cooling system for transportation, and wherein the plurality of panels are configured to extend from the housing to protect openings in an air intake of the housing and to allow passage of air through the air intake in the open position.

The present disclosure relates to a portable air purifier. The portable air purifier includes: a fan case having a narrow width portion at the front thereof and a wide width portion at the rear thereof, the narrow width portion including a space the radiuswise width of which is less than the radiuswise width of the wide width portion, and a fan blade protruding centrifugally further than the space formed inside the narrow width portion while being disposed at the wide width portion.

A heater assembly for a heating, ventilation, and/or air conditioning (HVAC) system has a heater and a controller enclosure. The heater has a plurality of heating elements in a frame that has two opposing ends. The controller enclosure has two end walls and a plurality of side walls in a non-rectangular polygonal configuration. One of the two opposing ends of the frame is coupled to one of the two end walls such that an orientation of the heating elements may be changed based on respective locations of the plurality of side walls of the controller enclosure.

A method of a fan system directing an air stream at a target can include receiving, with a controller, a first image from an image capture sensor and analyzing the first image from the image capture sensor to determine a first location of the target. The method can also include receiving a second image from the image capture sensor and analyzing the second image from the image capture sensor to determine a second location of the target. The method can also include comparing the first location of the target and the second location of the target and sending a signal to a first motor to rotate a housing about a first axis respective to a base to direct an air stream exiting an outlet of a channel at the target.
