After installing that the heat
pipe technology on the air handler on the first
floor, we have been able to maintain a relative
humidity on the first top floor here on this stack
area of about 55% which is totally acceptable.
The interesting thing that in creating that problem
the solution to it costed us about $7,000 to put
the air handlers to have the heat pipes installed
in the air handler. Since that time and 5 years
after that , we’ve saved approximately $15,000
per year on a $7,000 expenditure.
The potential financial savings is mind-boggling.
You have heard about heat piping using increasing
humidification and you have seen several installations.
The potential of heat piping that particular application
varies between 20 % and 50 %. 50% is when you
are using the heat pipes to replace reheat which
is an ideal application. But we had the machine
tested at the University of Arizona at Tucson.
Side by side we have the major manufacturers high
efficiency air conditioner. Our machine with the
heat pipe run on 51% less electricity.
We have lowered our tonnage HVAC which lowers
the amount of electric usage that we have on the
total building by about 22% and we’re extremely
excited about this feature.
We designed heat pipes in our patented curve.
Heat pipes simply slide in to that curve. It takes
literally two to three minutes to slide them in.
It’s just like sliding a dresser door. Very very
simple. So, we designed the heat pipes into our
curve assembly. On a new store, the stores automatically
take a curve for the air conditioning unit to
sit on. So, it is just a matter of us building
the racks inside that curve which slide the heat
pipes make very very simple. Our retrofit application,
we designed what we call a curve adaptor. You
can simply go out to the existing store, lift
the air conditioning unit up off the existing
curve set the curve adaptor in place with heat
pipes put the unit back on it and within thirty
minutes retrofit is done. We put together a test
with EPRI (Electric Power Research Institute)
and Alabama Power and Mississippi Power, a test
for the K-mart corporation and the test site was
chosen along with Mississippi. And we put heat
pipes in five of the existing seventeen units
on the roof there. Just to see how the building
would react for as a moisture control. That is
under test right now. EPRI is doing the monitoring
on it which is the research foundation for EEI
(Edison Electric Institute). So EPRI is going
to be doing the documentation as for as the follow
up and see how the heat pipes are actually performed.
