The invention
- The
problem to be solved:
To reduce or
eliminate green-house effect in buildings
constructed with transparent roof.
|
- Definition:
In a hollow body
heat absorbing material is circulated,
into which light-absorbing material could
be dispersed if necessary. Colour and
light absorbing capability of light
absorbing material are adjustable.
|
- Presentation:
Multi-layer hollow
polycarbonate sheets, built in accordance
with the illustration, are filled with
liquid mixed with black or colour plastic
granules.
In basic state granules are floating on
the top, or sink to the bottom of the
liquid and hollow, depending on specific
gravity conditions. In this case
polycarbonate sheets are transparent.
But if we make the fluid circulate by a
pump granules will make the sheet partly
or entirely not transparent, depending on
their colour and quantity. Thus the sheet
will shade and pre-heat household warm
water just like a solar panel.
|
- Application:
Buildig industry
|
- Advantages:
Environment
protection: significant energy saving, as
under-roof space shouldn’t be cooled.
Active solar energy utilisation: 0.5
kWh/m2 household warm water can be
produced daily.
Better life quality: Colour and strength
of natural light are adjustable as
requested.
|
- Stage
of development:
Laboratory
experiments are completed. I have
selected the best heat and light
absorbing materials. (There are two
colour-changing (“chameleon”) light
absorbing materials available at present.
A popular application of them would be to
manifest the colours of two sport teams
during the match on the roof of the
stadium.) The best possible circulation
conditions in the roof are worked out.
Plans of the variations of equipment to
select or change the most applicable
light absorbing material are completed as
well. Pilot tests of that had been
carried-out.
