U.V LED light strip sticker - HVAC energy saver by SAADITHYA

Your proposal sounds thrilling and offering quite a bit of impact. Especially in tropical and sub-tropical regions, there must be lots of HVAC in use, so the proposal can be scaled.
Bringing an invention to innovation, and wide use can be quite a challenge.

Thanks Ralf for your feedback.
Partnership with HVAC manufacturers will be useful, if the product once developed can be sold with the HVAC units and it can be integrated in new models of HVAC. The Consortium Advanced UV for Life along with MIT media lab is a good partner for research & development.
U.V LEDS have been used for various purpose but not used as mentioned in the proposed idea in HVAC. Currently there is no way to stop spore & fungal growth in HVAC units this will lead to blockade of HVAC units and is responsible for airborne diseases, also it affects the efficiency of HVAC units.
Thanks again for your support.
Thanks & regards

This is a great proposal, it provides a simple yet elegant solution to a problem that I have otherwise experience to be quite difficult to deal with first hand.
Thank you so much for your participation! Keep up the great work.

Hi Teerth Brahmbhatt,
Thanks for your feedback & support I really appreciate it.
Dosages for a 90% kill of most bacteria and viruses range from 2,000 to 8,000 µW·s/cm2. Larger parasites such as cryptosporidium require a lower dose for inactivation.
We can assume 24* 7 operation but in reality it can be scheduled with a timer. It will also depend on number of U.V LEDs used & type of U.V LIght used. I propose U.V LED lights. Say I use TopTech UV light then 26.4 Watts * 24 hours/day * 10.5 cents kWh = $24.28 per year ($2.00 per month).
However I propose U.V LED lights which consume much lesser energy compared to TopTech UV light.
I only ask because I have worked with a product recently that is light scattering based lab instrument and it had to go through such an approval by regulatory agencies, something much closer to everyday residents would possibly face even more scrutiny.
Yes you are correct, U.V LED light is dangerous to humans but it can be used safely without direct exposure to skin from water filters to hospital sterlizers. Here in the proposed application, U.V LED is used inside the HVAC and it is no way causing direct exposure to human skin so it is safe for this application. Also U.V LEDs do not have good penetration capabilities so the disinfection of HVAC can happen in a closed environment.
Thanks & regards

How is your project doing now? Is it being implemented in the industry?
