An integrated system and process provides integrated control of the environment within a personal space. A tent or other structure suitable for forming a personal space, is in contact with, and may enclose, a user station. The system includes a control system, main controller, control modules, sensors, environmental units and other controllers that operate in an integrated fashion to provide a controlled environment within the personal space. The tent may enclose all or portions of the control system, main controller, control modules, sensors, environmental units and other controllers. Portions of the control system, main controller, control modules, sensors, environmental units and other controllers may reside outside tent. A process for providing environmental control of the personal space includes learning capabilities.

A method for providing personalized comfort to occupants of an environmentally conditioned space includes sensing a pre-adjustment pressure within a variable air volume diffuser, remotely adjusting a position an individually-adjustable directional outlet of the variable air volume diffuser, sensing a post-adjustment pressure within the variable air volume diffuser, and modifying the airflow through the variable air volume diffuser such that the post-adjustment pressure is equal to the pre-adjustment pressure. The variable air volume diffuser includes individually-adjustable directional outlets and a controller configured to regulate air pressure within the variable air volume diffuser when an individually adjustable directional outlet is adjusted. A user device in operative communication with the variable air volume diffuser includes a user interface to remotely adjust an adjustable directional outlet of the variable air volume diffuser to provide personalized comfort for the user. In embodiments, the variable air volume diffuser responds to spoken commands.

An air-conditioned booth for accommodating a small number of people. The air-conditioned booth includes a transparent wall structure extending from a base to a top and enclosing an interior space. The booth includes a duct system and connected air conditioner for cooling air and directing the cooled air into the interior space of the booth. A damper system is operatively connected with the duct system and is positionable to place the booth in a non-cooling mode and a cooling mode. Air cooled by the air conditioner is directed to the ambient air surrounding the booth by the damper system when the booth is in the non-cooling mode and air cooled by the air conditioner is directed into the interior space of the booth when the booth is in the cooling mode. A vending unit is operatively connected to the damper system and controls the damper system.

An air filtering shelter 100 comprising a shelter frame 110 comprising a plurality of frame members 112 defining a sheltered area 102. Filter media 120 extends across the plurality of frame members 112, where the filter media 120 is disposed over the sheltered area 102. An airflow guide 130 extends across the plurality of frame members 112 between the sheltered area 102 and the filter media 120. The airflow guide 130 is impermeable and the filter media 120 and the airflow guide 130 define an airflow channel 125 between them. An airflow generator 140-1 is coupled to the shelter frame 110. The airflow generator 140-1 has an inlet 142 in the airflow channel 125 and an outlet 144 in the sheltered area 102.

A headgear is described that includes a first air purifier, a second air purifier, a first microphone, a second microphone, and a control unit. The control unit analyses a first signal output by the first microphone and a second signal output by the second microphone to determine a direction of wind. The control unit then controls the relative flow rates of the first air purifier and the second air purifier in response to the determined direction of wind.

An air purification and disinfection system includes an apparatus having a housing, an ultraviolet disinfection chamber, an air mover, and an air distribution unit in communication with the disinfection chamber. Air is passed through the disinfection chamber where it is purified and disinfected before it is delivered to the user of the apparatus through the air distribution unit. The apparatus can be configured as an open or a closed circuit system. The system may be configured to purify air in an airplane, a conference room, a classroom, or as a portable unit for an individual user. As a portable unit the disinfection chamber can be incorporated into a back pack, a vest, a purse, a briefcase, a shoulder bag, a cervical collar, or any other format for being carried by the user.

A local cleaned air supply device includes: a power supply unit, a control unit, and a freely rotatable cleaned air supply unit. The cleaned air supply unit, which includes a fan driven by driving electric power, and of which a height position, a swing angle in a left-right direction, and a tilting angle can be freely adjusted, is configured so that air drawn therein is cleaned by passing through a pre-filter and a main filter and is then discharged toward a front side thereof from an air discharge opening. The cleaned air supply unit also includes a sighting unit that visualizes a range in which high cleanliness is guaranteed in a space on the front side of the cleaned air supply unit. The sighting unit includes a plurality of laser emitting units that output laser beams, to surround the range, toward a front side of the air discharge opening.
