Your talking about the mattresses now. I as only talking about HVAC prior. They are two different applications. But again you like to argue and think you right when you have no idea what your talking about. The mattress aspect has been on the news and used in Europe for 30 years. Th UV-C Light will penetrate a mattress deep enough to kill, mold, mildew, viruses, bacterias, dust mite eggs and it alters the DNA of the dust mites as in other micro- organisms so that they are unable to reproduce and eventually will die as well. The vacuum is to extract as much as possible so the UV-C light is more effective and to rid the areas of as many dust mites as possible. The spray is produced by a major corporation that is use as maintenance between cleaning for control. You might want to read more about a topic before you present such strong opinions. You might want to read more on my website to learn more about real studies, since you were so kind enough to point it out. I never said it turns the bad stuff to dust is will disintegrate them. You really do need some help.
BELOW ARE THE WEBSITES THAT YOU LISTED ABOVE. BELOW EACH OF THE WEBSITES IS THE INFORMATION THAT I HAVE READ THERE. CAN YOU READ? DO YOU KNOW HOW TO? YOU JUST KEEP GOING MAKING IGNORANT STATEMENTS AND CLAIM THAT I NEED TO READ UP ON THE SUBJECT. NOT THE PROBLEM, THE PROBLEM IS THAT YOU NEED HOW TO READ AND EXPRESS AN OPINION WHEN AND ONLY WHEN YOU KNOW WHAT YOU ARE TALKING ABOUT NOT JUST BLAH BLAH BLAH BLAH. FIRST USE YOU BRAIN THEN SPEAK OR TYPE. UNTIL THEN STOP STATING THINGS ABOUT ME THAT ARE NOT TRUE. I HAVE RESEARCHED AND I CONTINUE TO DO SO AND I DON'T PASS COMMENTS OR MAKE STATEMENTS UNLESS I AM 100% THAT I KNOW WITH FACTS ABOUT WHAT I SAY. YOU MIGHT TRY THE SAME.
These systems only treat the evaporator coil and either down stream air or mix air chambers. The condenser coil is mounted outsidein the condenser, to discharge heat. I NEVER said I know more about HVAC than any of you. I said I wanted to learn from you more.
That's some more of your notmagicscience. Most of what's in it AFTER it's dead is still food for the mold. UV can't completely break down bacteria, et.al.., at the residence time your lights have to work on them. It mostly just kills them, as much from oxidization action of the ozone generated as from the direct incidence of the light. Even breaking up the proteins and carbohydrates like cellulose still yields compounds that are "organic" in nature (ever heard that term? No, I didn't think so). Many of even the simplest organic compounds can still be processed as food for molds and bacteria.
So... you don't eliminate _anything_ that causes all these problems except for living molds on the surface of the evaporator; and there are many places in the air stream where they can live that your silly lights can't reach -- like on the _other_side_ of the evaporator. (it have two side?)
Yes the UV-C light will kill them and break them down. Organic are one that are most easily killed by the UV-C light. If a typical HVAC system has 6 - 7 air exchanges per hour, everything will have been circulated once the cfm of a system has been completed. Most HVAC systems on bring in 10% of fresh air to maintain their efficiencies. The rest is fouled air full of contamination recirculated over and over again. Engineers, scientists, EPA, Gsa, McGill Study, 3rd party case studies, petri sample test, etc. all confirm the effects of the UV-C light. These are not my opinions, forget everything I have said and argue with experts in the field that have developed, tested, and evaluated UV-C Light. They are
Well, photoactivation and the resultant oxidation will fundamentally change the food source, so the food source is (possibly) less toxic, less allergenic. But you are spot on, "reinfection" downstream is only prevented by ozone and NOx formed by the lights. And mold is the problem usually, not the food source. If anything the oxidation makes the food supply even more tasty and desirable.
Think cube. It has six sides in 3D space, "1.5" of which can be bathed in UV-C light from a single source/bulb (which doesn't reflect too well). The "0.5" face is the fins at a very steep angle, which is really not very good coverage.
UV lamps are not a bad idea, but they really need to be used to periodically treat all the areas in contact with the air, and the condensation sump too. And they have to be cleaned, along with all the treated surfaces. They might stretch out the period between cleanings though... "silly" might not be the best thing to call them. Or the worst.
Glad you pointed these areas out. Aluminum is the best reflective source for UV-C Light so the light will be reflected and bounce in many areas (including the 0.5 fin) of the HVAC and Clean areas that from conventional cleaning techniques as in power washing that will add water (moisture) to allow the mold to grow a faster rate than it was prior to the cleaning. or uncloogers that contain chemicals that will add VOC's to the already fouled air that is being circulated throughout the HVAC system.

Gotcha! Earlier you said that condensate (water...duh!) was what flushed the "dead" materials off the evaporator. Now you're saying the presence of water worsens the situation.
Yeah, "certain" uncloogers(sic) contain VOCs. Ordinary water solutions of surfactants don't.

I see, now! I didn't understand your notmagicscience! They're ozone lamps that are non-producing!
These lamps have a short enough wavelength output to destroy organics, but not enough energy to pump O2 up into O3.
Ahhhhh....It's all clear now.
(At what distance did you say they were effective? And, for what linear rate of airflow within that range?) (Oh... you might be interested to know that in small concentrations, ozone is a mood elevator, and not irritating.)
Condensation is going to happen on the coil period. Even with the UV-C application the condensation will still be present, but it will prevent mold, etc. I said if you were to power wash a coil you will add large amounts of water that will not cure a problem but in fact add to the problem. Condensation is just a little bit different than a pressurized wand spaying gallons of water.
Loyd UV-C Light is non producing ozone in it self, generally you need to implement some sort of metal (or a combination of metals) in liquid form (to coat the bulb) or a plate (actual pieces of the metal in contact with the bulb) of it to get the UV-C Light to interact with it and then it will produce ozone. The bulbs have an output of 254 nm, which is the ideal range for the germicidal spectrum of UV-C Yes, ozone is pretty much oxygen in a plasma state, so it will elevate a persons mood but people can be irritated (respiratory system, eyes, throat) by it as well. If used it needs to be monitored and sized for the correct application. There are factors that are needed, and depending on what pathogen(s) you want to target. Let's say irradiate a coil for mold; you would need to know the size of the coil, the cfm of the unit and the size of the plenum - typically you would add 2-3 above and below the coil and 3 1/2 for each side for the bends extending off the coil. Then this is put into a software program to determine how much UV-C will be needed to treat the area. You will given an installation diagram; how many units, where to mount the units, at what height and the horizontal position of the units.
No aluminum is the best reflective source for UV-C it will not allow the UV-C to produce ozone. But you getting close it is a metal, but Titanium for an example in contact with the UV-C would work to produce ozone.

Aluminum *at best* compton scatters UV-C into less-energetic-than-UV- C, which means the first reflection is less effective at sterilizing than the incident radiation was. That is why I "rated" it as 0.5 effective.

not the severe decrease in reflectance of aluminum at shorter wavelengths. And this is *polished* aluminum, not that tortured and roughened stuff in an A/C unit.
Sorry, no. The reflected UV does not "scour" the fin surface. Only "elbow grease" can do this. All the light can do is keep it bright and fully oxidized.
