Techical Corner: The Science of Loafing Time

Life presents all of us with choices and decisions. When it comes to work responsibilities, machines have been increasingly valuable, giving us more time to accomplish other tasks. In addition to machines, our own ingenuity allows us to modify even our procedures to lessen work and time.

Human ingenuity has provided us with many devices that take away burdensome tasks, for example dishwashers or self-lubricating equipment or “automatic” temperature controls and so on. There is no question that such devices improve our quality of life, freeing us up to accomplishing other tasks or alternately just giving us “loafing” time where we can relax.

There are many jobs that are necessary but we don’t particularly care to do, like washing dishes or cleaning air conditioning coils often are put off until the last minute. Some of us might even like to put up a curtain to cover dirty dishes so we don’t have to look at them until we run out of dishes.

It is easier to put off cleaning with coil cleaning because the coils are already inside an area that we can not see anyway. No curtain is required here!

Tales of wasted energy efficiency from dirty coils and bacteria/fungus buildup (which are true by the way) do not seem to entice the average guy to clean coils more frequently. In this case the out-of-sight and out-of-mind concept applies.

Adding to the reluctance of cleaning coils in general is the rather significant fact that almost all facilities do not have the manpower to do it. So that pretty well seals the deal of only cleaning coils when the pressure drop is so high the air flow has dropped by 30% or even more.

While no one has yet to develop an in-place automatic machine to clean coils at the push of a button, human ingenuity has provided a solution.

It is more than just “nice” thing to do than cleaning coils – the benefits are there, and are proven accurate. Less back pressure on the fan system, less restrictions by fungus or mold and bacteria on the coils make significant differences in not only energy consumption, but air quality from the odors that dead and decaying microorganisms emit. Topping those factors off, wouldn’t it be just great to look inside of the HVAC air handler unit and see a glistening interior free from odors, free of any drain pan deposits along with crystal-clear water? And most importantly, with no extra work on your part?

A dream you say? No, it is simple and economical to have this now.

At CRT, our emphasis over the past 25 years has been in developing advanced products that keep air handlers looking nice where it counts – in the interior.

The development in our in-house R&D lab of these products using the latest technology we develop and manufacture in-house insures that any air handler using CRT solutions will be and continue to be clean. Benefits of increased efficiency, freedom for microbial odors, unexpected overflows and overall cleanliness are real. It has been said you could set up your office inside the air handler it is so clean. Can you say you could do that now with your existing air handler?

Whether you can or not, it will benefit you to look at the many unique products we have created at our website http://www.cleanac.com.

Technical Corner: The Value of Coating HVAC Insulation

Most air conditioning systems built over the last thirty years have air distribution pathways, or ducts, lined with fiberglass insulation. Unfortunately, insulation absorbs dirt and other matter, including microbial spores, greases and even oils. These particles penetrate the insulation, becoming entrapped and inaccessible for removal.

Due to particle entrapment, it is common for insulation to get dirty, and downright nasty in some cases. Even a slight bang on the duct work or unit sidewalls could send a cloud of dust and other matter into occupied areas. Listed below are a few of the problems commonly experienced:

1. Mold entering through the air stream is responsible for most objectionable odors encountered in systems. Entrapped mold spores eventually grow, due to the presence of humidity and nutrients within the insulation, causing undesirable consequences for building owners.

2. Organics, such as oil, can enter duct work if an air handler is located near a truck loading dock. The incoming air from around the dock usually contains diesel exhaust and other fumes. Some of these particulates, or fumes, may become lodged within the porous insulation, eventually becoming a source of odors.

3. Over the years fiberglass may lose its integrity. This results in small fiberglass particles being released into the air stream. In some cases, building owners can actually see black specs on desktops, which are later identified as being fiberglass particles.

Because of these problems HVAC contractors and NADCA duct cleaners often recommend cleaning and coating the duct work and insulation. As stated above, uncoated fiberglass insulation contains dirt and other matter that cannot be successfully cleaned. However, coated duct work is smooth and easily cleaned just by wiping the surface of the material. Additionally, sealing ducts with a coating eliminates the release of fiberglass emissions into the airstream.

Purchasing and recommending coatings can go a long way towards protecting your, or your customer’s investment, significantly reducing odors and emissions into occupied areas. For most building owners and contactors alike, it’s a win-win situation.
