How It Works
The earth's atmosphere is not only essential for breathing, but
important among its many functions is the ability to trap the sun's heat or
solar energy.
To prevent over heating there is a natural "atmosphere to space"
window through which some heat escapes into space under clear skies.
It is this natural heat-release window in the earth's greenhouse
which SkyCool uses to radiate a large portion of its heat directly into
space. In bypassing the heating of the nearby atmosphere it acts like a
"passive heat pump" removing heat from hot buildings
day and night.
As the University of Technology, Sydney discovered:
"SkyCool has been proven by our tests to be generally
capable of eliminating those heat gains through a roof associated with the
heating of the roof by the incident solar radiation. Such gains dominate the
heat inflow from traditional metal roofs even with batt type insulation
installed.
"It achieves this by a combination of two properties, high solar reflectance and high thermal emittance, which we have verified by direct measurement."
