A New Perspective on Indoor Air Quality

Posted on Mon, Jun 04, 2012


    Hi! My name is Henry and I have recently begun working with UltimateAir.
This summer I will delve into health and energy efficiency in the context of the RecoupAerator: an Energy Recovery Ventilation system (ERV). Prior to joining this company, I had little knowledge of ERVs let alone the urgent need to ventilate my home. Doesn’t air conditioning bring in fresh air? Besides bugs and the occasional rogue bird, what’s wrong with opening a window? I had to take a deep breath and admit I was clueless to the issue. Parts of this blog will reveal how oblivious I was to the role of ERVs in ‘green’ home technology. By effectively filtering or diluting indoor toxins such as radon, pollen, and various formaldehydes, ventilation (via a RecoupAerator) is one of the most necessary yet easiest steps towards healthy living.

Mechanical Ventilation and Defrost

Posted on Mon, Apr 30, 2012
If you live in a cooling dominated or less than 4000 HDD climate - you might skip this article.  Else - in the world of heat/energy recovery mechanical ventilation there exists this nemesis known as dew-point temperature.....  and when this is associated with really cold outside conditions - this results in frost accumulation on a heat (energy) exchanger core.  You have warm moist air from inside the building exposed to a very cold surface.  There is no magic here- condensation at best, and frost at worst is going to happen.  Basically- the manufacturer must ensure that the core is not exposed to conditions that will result in frost accumulation on the core.  Every manufacturer has slightly different strategies based on the design of the core.  The UltimateAir RecoupAerator’s core is a random matrix fiber - and as designed does not start to frost until outside temperature drop below 12 F.  That is assuming that inside relative humidity at around 70 F is at or above 25%RH....  inside relative humidity plays a big role in whether or not frost occurs.  

The most common defrost strategy employed by manufacturers is known as ‘recirculation defrost’.  This strategy temporarily allows the leaving air to be redirected into the incoming air duct to warm it up enough to keep the core from frosting.  This cylce is generally 25-75% of an hour, every hour depending on outside temperature.  NOTE- that while this is happening - there is no (or very little) fresh outside air coming in.  This effectively lowers your fresh air ventilation rate... and turns your mechanical ventilator into a recirculation fan pushing air around for little reason.

UltimateAir has provided a pre-heat - pulse modulated solution that allows for no decrease in ventilation.  This is the most efficient solution which ensures the fresh air required for the health of the occupants in the home.  This is one of many other methods that best keep the incoming air at or above 12 F.

That is the short of it.  Defrost is a fairly complex notion to discuss with regard to the cost associated with it.  Know that UltimateAir has your health in mind first.

The Passive House Project

Posted on Thu, Mar 29, 2012

Enter the Passive House Project

Did you know that buildings are responsible for 48 % of greenhouse gas emissions per year and that 76 % of electricity generated goes to the building sector. In the past couple years, a new and innovative option has been brought about to establish a way to save our environment and save thousands of dollars in reduced energy usage. It goes by the name passive house which refers to the building style of buildings that are well insulated, air tight, and primarily heated by passive solar. In passive homes, energy losses are minimized and an airflow is provided through an energy recovery ventilator that purifies the air as well as prevents energy loss and keeps the air supply fresh and constant. This is where we come in as a company. Air ventilation systems such as the ones needed for a passive house are supplied by UltimateAir to ensure that the best air quality can be provided for any home, office, or school at an affordable cost. UltimateAir is one of the only companies that supplies air ventilation systems that are completely green and recover 95% of energy that would normally be lost. You don’t have to have a passive house to purchase our ventilation system called The RecoupAerator, but it makes it all the more affordable and healthy for your body, your home, and the environment.

Posted on Fri, Mar 23, 2012

Breathe Healthy

To be able to take a deep breath in your own home that you know is safe, pure, clean, and healthy is an assurance that you can’t pass up. At UltimateAir we have a product that will allow you to finally be able to trust the oxygen and air particles going in your body. The RecoupAerator, a top-of-the-line air filtration system, does all that and more! This ERV system recovers 95% of would-be lost energy as well as the filtration of air particles as small as 3.5 microns.
This month at UltimateAir we have created a webinar that will help you learn more about the RecoupAerator, your health and the many reasons why this product is for you. Each month we will come out with new and interesting topics that will relate to your life including tips for air safety, indoor air pollution, ways to improve your living, and green energy.
Make sure you visit our website at www.ultimateair.com/library/webinars/ to stay tuned for more of our webinars including our latest webinar on your health and ways to improve your health through your indoor air ventilation.

Thanks!

The Masking Tradition and Indoor Air Quality

Posted on Mon, Jan 23, 2012

Indoor air can be up to 5 times more polluted than the air outside

Today’s well-insulated and sealed homes trap odors and chemicals from rugs, furniture, and household cleaning products. Common sense and studies have shown that the by exhausting the pollutants and replacing this exhausted air with filtered, fresh air from outside, the quality of the home environment is uncommonly improved.  By adding heat and moisture recovery to this air exchange (in essence, recovering the energy already used to heat and cool the home), ventilation and filtration can be done for as little as 25 cents per day.
