Windows and Ventilators can have a Dust Frame or Solid Curtain. This can be fixed to windows like the Venetian Blinds but have to be leak proof on on the four sides. Mainly for Tropical and Equatorial Climates or Dusty areas near Roads etc.
Theory Points of Study
Layer-1 – Blocks most reptiles and Insects. Mosquitos to Fruit Flies. Aperture of Grid 1 sq mm. Material Aluminum.
Layer-2 – Another Layer similar to above, but facing the Outside Garden/Road. Aluminum Mesh 5 sq mm holes, resist Big Rats and others. It is thick and strong. Prevent Small Animals, Birds too.
The layers are as large as windows and are separated by 5-10mm by 12 nylon spacers. These may have small pins fixed in the gap in many places for “Action of Points” .
Layer-1 is anode, Layer-2 is cathode. Very High Voltage of Very Low Current, ionize air and coagulate dust, smells, pollen and other floating colloids. The plates when touched by Humans cannot cause any harm. Current less that 100 microamps. This ionizer powered by an isolated 24V adapter, draws very low power so it can be kept on all the times
Gaurd Layers –
Finger Gaurd layers on either side made of a decorative design with apertures smaller than fingers made of Environment Resistant Plastic or Epoxy. The layers are as large as the windows and can be the aesthetic part.
Solar Air Cleaner and Humidifier ACH Option
This is a Solar energy based Air Cleaner and Humidifier that covers 1/4 of the window like a Box-Slab at the Top of Window. It is optional and an addon internal module to the DustFrame.
The Solar Panel is as wide as window and fitted on top of windows at an angle outside. The length can be around 6 inches or less. The ACH fitted inside is 1/4th or less the height of window. The rest of window 3/4 is open for fresh air but the air is cleaned by ionizer frame like in explanation above.
The 1/4 ACH is a Box 6 inches deep on the inside, it is sealed but with a place to pour or guide water thru a mini water pipe, like the tubes used in Intravenous Systems used in hospitals.
The water collects at bottom of the box and drawn upward by a capillary action by an array of cotton wicks in matrix formation. The wicks grow from the floor of box to top.
Tiny row of low power fans powered by solar and rechargeable battery, draw air thru the ionizer layer and blows on the wicks array. The air exiting from this box is cool, clean and recharged with some humidity. it could also be one fan with long vertical geared turbine barrel plastic fin too, this sucks the air and blows on the wet wicks.
This system reduces dust, toxic colloids and allergy causants. It also prevents mosquito, flies, rodents and other small pests. It recharges the air with some humidity that keeps the room healthy and fresh. It consumes very low power and can be run on solar energy. The wet wicks also add a bit of cooling if the air is too warm.
