Mobile air decontamination and purification unit
First Claim
1. A transportable air treatment system comprising:
- an air intake;
a treated air outlet, there being an air flow path between the air intake and the air outlet;
a fan arranged to convey air along the air flow path;
an air treatment unit located downstream of the fan and the prefilter, the air treatment unit including a plurality of stacked trays; and
a duct that directs air from the air treatment unit towards the treated air outlet, wherein the duct is operable to clamp the stacked trays to help seal the stacked trays.

Abstract
A variety of transportable air treatment system improvements are described. In one aspect of the invention, the system is designed to significantly reduce the noise generated during operation. In another aspect, an easily removable cooling unit is provided. In still another aspect, an air treatment unit (as for example a plasma reactor) is provided that is arranged to filter the air stream, inactivate biological organisms and/or reduce or eliminate volatile organic compounds (VOCs) that are carried in the air stream. The air treatment unit may take the form of a plurality of stacked trays. In yet another aspect of the invention, the air treatment system further includes a duct unit that directs air from the air treatment unit to the treated air outlet. The duct unit is operable to clamp the stacked trays to help seal the stacked trays.

14. A mobile air treatment system comprising:
-
a housing having a door; an air intake located near a bottom end of the housing; a treated air outlet located near a top end of the housing, there being an air flow path between the air intake and the air outlet; a prefilter positioned within the air flow path and arranged to filter air drawn into the air flow path; a first chamber located downstream of the air intake and the prefilter, the first chamber having side walls and being sealed relative to the door, wherein a first one of the side walls of the first chamber has an access opening that faces the door and the first chamber further includes a removable plate that covers the access opening to seal the first chamber relative to the door; and a fan arranged to convey air along the air flow path; an air treatment unit located downstream of the first chamber and the prefilter; a removable cooling unit positioned within the first chamber, the cooling unit being arranged to pre-cool at least some of the air that passes through the air treatment unit, wherein the removable cooling unit is positioned as a free standing unit within the first chamber; and an electrical control system carried by the housing, the electrical control system being arranged to provide power and any required control to at least the fan and the removable cooling unit; and wherein the removable cooling unit has a first electrical connector that may be coupled to the electrical control system, a water input coupling and a water outlet coupling, and whereby the cooling unit may be installed by placing the cooling unit as a freestanding unit in the first chamber and coupling the electrical with a second electrical connector associated with the electrical control box and coupling the water input coupling with an associated water supply and coupling the output couplings with an associated water drain.

15. A transportable air treatment system comprising:
-
a housing having a door; an air intake located near a bottom end of the housing; a treated air outlet located near a top end of the housing, there being an air flow path between the air intake and the air outlet and the distance between the air intake and the air outlet being at least 150 cm; a prefilter positioned within the air flow path and arranged to filter air drawn into the air flow path; a first chamber located downstream of the air intake, the first chamber having side walls and being sealed relative to the door; a second chamber located downstream of the first chamber, the second chamber having side walls and being sealed relative to the door; a fan support plate that defines a boundary between the first and second chamber; a fan mounted on the fan support plate, the fan being arranged to convey air along the air flow path, wherein the fan is located substantially centrally relative to the side walls of the first chamber and the side walls of the second chamber, and a ratio of the hydraulic diameter of the second chamber to the diameter of the fan is at least 1.4; an air treatment unit located downstream of the second compartment, the air treatment unit being arranged to further filter air conveyed along the air flow path; and wherein the second chamber is substantially balanced aerodynamically from side-to-side and from front-to-back as seen by the fan in order to help reduce the probability of air pressure imbalances on the fan that contribute to noise generation. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
