Air-wall room system

Abstract

An air-wall room system, suspended from a room ceiling, having a compressed air discharge duct. The air discharge duct is used for circulating compressed air into a hollow, four sided, upper air-wall frame with air openings. The air from the upper air-wall frame is circulated into a work space. The hollow upper air-wall frame includes air discharge ports for creating an air-wall. The air-wall, similar to a curtain, prevents toxic gases from escaping outside the work space. Corners of the upper air-wall frame are attached to vertical frame members. A bottom of the vertical frame members is attached to corners of a hollow, four sided, lower air-wall frame. The lower air-wall frame includes vacuum ports for receiving the bottom of the air-wall. A side of the lower air-wall frame is connected to a vacuum air exhaust duct. The air exhaust duct is used for drawing a vacuum in the hollow lower air-wall frame and exhausting the air-wall out a vacuum air exhaust duct.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) In FIG. 1, a perspective view of the subject air-wall room system is illustrated and having general reference number 10. The air-wall room system 10 is suspended from a room ceiling 12. The system 10 includes a compressed air discharge duct 14 for circulating compressed air, indicated by arrows 16, into a hollow, four sided, upper air-wall frame 18. One side 17 of the upper air-wall frame 18 includes air openings 20 for receiving the compressed air therein. Also, the air 16 is circulated outwardly through the air openings 20 into a work space 22 and between the sides of the frame 18. The work space 22 is used for cannabis oil extraction and other applications.

(6) The hollow upper air-wall frame 18 includes air discharge ports 24 along it's length and in the bottom of the frame 18 for creating an air-wall, shown as vertical arrows 26. The air-wall 26, extending downwardly and similar to a curtain, eliminates the need for a hard wall structure and prevents toxic gases and the like from escaping outside the work space 22.

(7) Extending downwardly from corners of the upper air-wall frame 18 are vertical frame members 28, typically 8 to 10 feet in length for providing a sufficient height for the workmen in the work space 22. The bottom of the vertical frame members 28 are attached to corners of a hollow, four sided, lower air-wall frame 30. The lower air-wall frame 30 includes vacuum ports 32 for receiving the bottom of the air-wall 26. A side of the frame 30 is connected to a vacuum air exhaust duct 34 for drawing a vacuum in the hollow lower air-wall frame 30 and exhausting the air-wall 26 out the duct 34.

(8) The lower air-wall frame 30 surrounds an elevated floor 36 with air exhaust vents 38. One side of the elevated floor 36 is connected to the exhaust duct 34. The toxic air, shown as arrows 40, is shown being drawn into the exhaust vents 38 and into the exhaust duct 34, thus providing a safe environment for the work space 22. A portion of the floor 36 and the lower air-wall frame 30 is cut away in this drawing.

(9) In FIGS. 2 and 3 a cut-way perspective view of a portion of the lower air-wall frame 30 is shown with the elevated floor 36 and air exhaust vents 38.

(10) In FIG. 4, a perspective view of a gas sensor 42 is shown disposed next to the air exhaust vents 38 in the top of the elevated floor 36. As the toxic air 40 exits the work space 22, the gas sensor 42 will detect the level of gas-air mixture in the workspace and alert the workman when a high level of gas has been detected during the oil extraction operation. This gas sensor will allow for increased air flow or air pressure into the air curtain to be activated at the time of sensing a toxic or flammable gas. The variable air flow will minimize the costs of the HVAC costs for heating and cooling the room and adjacent spaces. This variable air flow is incorporated by reference to U.S. Pat. No. 10,232,286 to Havelick.

(11) While the invention has been particularly shown, described and illustrated in detail with reference to the preferred embodiments and modifications thereof, it should be understood by those skilled in the art that equivalent changes in form and detail may be made therein without departing from the true spirit and scope of the invention as claimed except as precluded by the prior art.
