English Abstract





ABSTRACT OF THE DISCLOSURE

There is provided a method and apparatus for
preheating ventilation air for a building. A solar
collector is provided along a south-facing wall of the
building, having a bottom entry for outside air, and an
upper exit to a fan or other air-moving means. The fan
withdraws air from the collector, after it has been
heated by the sun's energy and also by picking up some of
the heat normally lost through the building wall, and
then ejects the air into the building through a duct
located preferably at ceiling level.


Note: Claims are shown in the official language in which they were submitted.

CLAIMS
What we claim is:
1. A method of preheating ventilation air for a building
comprising the steps:
a) providing a vertical, air-heating solar collector
surface on a south facing wall of the building, in such
a way that heat being lost from the interior through the
south-facing wall is available at said surface and can
contribute heat to air passing through the solar collector
panel means,
b) providing glazing spaced outward from said surface,
c) passing outside air through the solar collector
panel means in a generally vertical direction from a lower
inlet, the air passing between said surface and said glazing,
and heating the air with a combination of solar heat and
the heat being lost from the interior through the south-facing
wall, and
d) withdrawing the heated air from the solar collector
panel means at a location near the top thereof and using
air-moving means to expel the heated air into the interior
of the building.
2. The method claimed in claim 1, in which the heated
air is expelled into an interior space of the building
near the top of such interior space.
3. The method claimed in claim 1 or claim 2, which includes
the further step of shading the solar collector means
from the sun's rays when the sun is higher in the sky,
by providing a permanent hood means at the top of the
collector means, the hood means overhanging the collector
means.
4. Apparatus for preheating ventilation air for a building,
comprising: air-heating solar collector means provided
on a south-facing wall of the building, the solar collector
means including a blackened surface in heat-transfer contact
with said wall, and glazing means spaced from said blackened
surface, an air inlet along the lower edge of said solar
collector means, and an air exit adjacent the top thereof,
air-moving means and duct means arranged to allow heated

air to be withdrawn from the collector means and expelled
into the interior of the building, the air exit communicating
with said air-moving means.
5. The apparatus claimed in claim 4, which further includes
hood means overhanging said solar collector means and
shading the same from the sun's rays when the sun is high
in the sky.
6. Apparatus for preheating ventilation air for a building
having a south-facing wall, comprising:
a blackening material applied to a portion of said
south-facing wall,
glazing spaced from the blackened portion to define
an air passageway between the glazing and the wall, through
which outside air can pass from an inlet at the bottom
edge thereof to an exit adjacent the top edge thereof,
duct means within and adjacent the top of an interior
space of the building, and
fan means for withdrawing air from said exit and expelling
it into said duct means, the duct means including aperture
means through which air can escape from the duct means
into said interior space.
7. The apparatus claimed in claim 6, which further includes
a hood overhanging the glazing at the top thereof, to
shade the same from the sun's rays during late spring
and early summer when the sun is higher in the sky.
8. The apparatus claimed in claim 6 or claim 7, in which
the duct is made of a flame retardant fabric, and in which
the aperture means includes openings in the fabric of
the duct.
