Abstract

Abstract A zig zag wire mesh, form/folded, non sag evaporative filter panel that provides an improved level of consistent airflow/temperature performance. This is due to the nil allowance of filter fibre movement, migration or displacement from the original optimal placement of the said fibre within the form/folded zig zag panel section, which results in cost savings and more effective air conditioning across the board.

Description

Ztg Zag Form/Folded Wire Mesh Non Sag Evaporative Filter Panel

The purpose of the present invention is to provide the evaporative air conditioning industry with an improved filter panel profile that does not allow for sagging or displacement of filter fibre

The traditional evaporative filter panel relies upon the placement of wood fibers between layers of net material that is then suspended vertically as pinned to metal or plastic pad frames. The frame is then placed vertically in a fan forced air flow with a continuous downward flow of water from a distributor supply at the top of the filter pad frame.

With the trickle flow of water over the filter fibre adding significant static weight to the fibre, coupled with the constant horizontal air flow through the filter pad, individual, unpinned fibres tend to migrate downwards, even when stapled or pinned to the frame, the inevitable result over a short period of time is an uneven spread of fibre with large air gaps forming in the filter panel profile, leading to a poor and in-efficient evaporative process. This is particularly the case when insufficient pinning of the new filter material is carried out at the point of filter fibre replacement by contract servicemen, which occurs seasonally as a rule.

By contrast, the zig zag form/folded wire mesh filter anel has wood fibres placed between two layers of 6.5 x 6.5 x 6 mm galvanized wire mesh, of a predetermined width, to a depth of 40 mm, that is form/folded, zig zag fashion, into a vertical panel. The cross section measurement of each complete zig zag form is 125 mm on a 45 degree plane, returning back at 90 degrees for 125 mm to form the next section. This zig zag process is continued till the predetermined length of the panel is achieved. The novel aspect of the invention means that the heavier the saturated fibre becomes, the more firmly the fibre, (now softened by water), is pressed in-situ, into the wire mesh that is lying on a 45 degree plane, making it virtually impossible for the filter fibre to sag or become displaced.

By applying the novel aspect of this invention to the conventional evaporative filter panel, the evident benefits are many, including, but not limited to: a) A consistently lower and more even temperature of the filtered air through the panel. b) An extended duty cycle because of the integrity of the filter material being maintained. c) Overall savings in maintenance and filter material replacement costs.

Claims (5)

1. Claims 1 A zig zag form/folded, wire mesh non sag filter panel frame for use in the evaporative air conditioning industry that eliminates filter fibre, sagging or displacement.
2. 2 A zig zag formed wire mesh non sag filter panel frame according to claim 1 wherein the said frame is constructed out of galvanized wire mesh of a predetermined length width and cross sectional area.
3. 3 A zig zag formed wire mesh filter panel frame wherein the wire mesh apertures may be 6.5 mm x 6.5 mm x.06 mm to effectively arrest migration of the filter fibre from its original optimal placement postion.
4. 4 A zig zag formed wire mesh filter panel wherein the individual wire mesh sections lie at 45 degrees to the horizontal plane for a predetermined length and cross sectional area and returning at a 90 degree angle to the preceding section, 'ad infinitum.'
5. 5 A zig zag, form/folded wire mesh, non sag filter panel according to claims 1-4 wherein the said frame allows for an improved and consistent airflow/temperature performance in evaporative cooling systems.
