THE PLENUM
SYSTEM
Cave
men lived in caves and enjoyed the normal earth temperature of 70 Degrees
Fahrenheit. I took this concept into the present in Phoenix, California over
two decades by using the crawl space of a home as its cooling chamber and
slowly circulating the cool air throughout the structure for a very efficient
system. We further installed underground ducts from underground to pull in
fresh air using the earth’s natural temperature to mix and cool down the intake
air. A great success in Arizona. However, in California, we were denied the use
of this Plenum system, citied as a Building Mechanical Code Violation. Go
Figure!
Earth
ducts are widely used in Germany and other parts of Europe. Warm air is drawn
into the duct using low-pressure mechanical fans, where it gradually cools as
it passes thru the ducts and is than routed into the interior space. The earth
ducts work in parallel with the conventional cooling and heating systems and
reduces energy costs. Studies have proven that virtually all heating and
cooling loads have been eliminated by this method.
