## Abstract

A portable enclosure is configured to mix room air with a controlled amount of exterior air via one or more flexible conduits disposed between the enclosure and an exterior window. At least one flexible conduit is connected to a barrier structure which is designed for sealable placement within the window. One or more mixing dampers are employed to control the amount of exterior air supplied to the enclosure. An air moving device delivers exterior air in controlled amounts to the enclosure which is designed to be moveable so that a more desirable (fresher, cooler, and more contaminant free) stream of air is deliverable to the personal space of an occupant to satisfy ventilation and temperature requirements.

## Claims

### Claim 1

A device for mixing air sources, said device comprising:
a portable enclosure having a first air inlet opening for receiving controlled amounts of outside air, a second inlet opening for receiving inside air, and an air outlet opening for exhausting a mixed volume of said outside air and said inside air from within said enclosure for direct delivery to an individual user's location;
an air moving device for moving air from within said enclosure through said air outlet opening, said air moving device adapted to provide a flow of air directly into said user's personal space at said individual user's location, said air moving device adapted to provide personal ventilation to a breathing zone of said user;
a first flexible conduit, exterior to said enclosure, attached to said first air inlet opening;
a barrier structure having an opening therein for receipt of said first flexible conduit, said barrier structure being suitable for sealable placement in an exterior window; and
a second flexible conduit, exterior to said enclosure, attached to said first air outlet opening in said enclosure, for direct delivery of said mixed volume of interior and exterior air to said individual user's location.

### Claim 2 (depends on 1)

The device of claim 1 further including a damper to modulate air flow between said enclosure and said outside air.

### Claim 3 (depends on 2)

The device of claim 2 in which said damper is disposed at said barrier structure.

### Claim 4 (depends on 1)

The device of claim 1 further including an air flow limiting device to modulate air flow through said second inlet opening.
