AIR. CIRCULATORY SYSTEM
William E. S. Strong, New York, N. Y., assignor
to John B. Pierce Foundation, New York, N. Y.,
I a. corporation of New York

form the air-collection chamber of the system.
This invention relates to an air circulatory sys
Such dwelling houses may be designed without
basement and have de?ned between the floor and
tem.
More particularly the present invention relates
to an air circulatory system for heating and venti
% lating and otherwise air conditioning the in
terior of a structure such as a dwelling house.
The present system effects a forced flow of air
over a central thermal and/or other conditioning
unit and distribution of the thereby treated air
3% through appropriate chambers, such as the rooms
of a dwelling house, for utilization, and provides
for the return of such used air, thereafter, to an
appropriate chamber, followed by a re-?ow of
such air over the thermal and/or other condi
tioning unit or units to afford. continuous condi
an insulated false floor, the plenum chamber of
the system. The conditioning conduit may ex- U5
tend vertically between such plenum chamber
and the attic i. e., air-collection chamber, at any
convenient location in the house, and the remain
ing space between side-walls, ?oor, and ceiling
of such house may- be divided as desired into
rooms, 1. e. the utilization chambers of the system.
The ‘floor of each room is preferably provided
with one or more air inlets from the, plenum
chamber, and the ceiling of each room is prefer
ably provided with one or more air outlet open
tioning of air in the system and continuous cir
culation of such conditioned ‘air distributively
throughout the utilization chambers of the sys
tem.
'
Advantageously, the air collection chamber is
provided with means for admitting fresh air from
the outer atmosphere, and regulating the admis
sion of such fresh air into the circulatory system.
Desirably, also, one or more of the utilization
25 chambers are provided with means affording
partial cut-01f for such chamber or chambers
from other component chambers of the system,
such‘ means allowing admission of conditioned air
from they system to such partially cut-off chamber
or chambers but effecting discharge of 'used air
ings into the attic, such ceiling openings being
preferably at locations in the room remote from
that of the floor openings. Air is drawn from
the attic, by suitable air circulating means, and
?ows down through the conditioning conduit over M0
a suitable heater, humidi?er, cooler, or other con
ditioning unit or units positioned therein, into the
‘plenum: chamber for distribution .through the
variantly located floor openings of the room of
the house. The used air from the'rooms passes
into the attic through the variantly located ceil
ing openings, and, as thus collected, isv re-condi
tioned and re-‘circulated continuously, as desired.
Further features and objects of the present in
vention will be apparent from the following de- 30
therefrom .into the outside atmosphere rather
tall description, together with the accompanying
than the return of such air into thesystem for
drawings, in which
re-circulation.

ditioning' conduit extending between the air-col
lection chamber and the plenum chamber, and
communicating therewith at its ends, outlets from
the plenum chamber into the utilization cham
bers, outletsfrom the utilization chamber‘ into
the air-collection chamber, a thermal or other

‘ Referring to the drawings which represent an
application of the present air circulatory system
to one type of dwelling housefor heating and 40
ventilating and otherwise ‘air conditioning the
same; illustrated therein is a dwelling house pref
erably one story and without basement. Such
dwelling house has an, attic as at lllde?ned be-l

conduit into the plenum chamber, and thence, lection chamber for the‘house. '
distributively through, the utilization. chambers ' The floor l5 of such dwelling house'is provided
back to the air-collection chamber. ‘

The ‘plenum chamber i8 is spaced below the
air-collection chamber iii a distance equal to the

desired height of the space _to be provided with
conditioned air. ‘Such space is bounded by the
plenum chamber [3 for distribution through the
exterior 'side walls I8, 20, 2i and 22, respectively

One or more of the rooms, i. e. utilization
chambers, may be provided with a vent‘such as
structure 2611 de?ning a combustion chamber, and
an outer hood 26b de?ning, together with the
25 inner structure 26a, a thermalizing passage 260
between open and closed position. Such room
or rooms may be partially cut o? from the air
for air. A smoke pipe 21, communicating with
the innerv structure 26a, cooperates with the
draft-opening 23 to promote, in the usual man
ner, combustion within the furnace. Such draft
30 opening 23 may communicate with the plenum
chamber IS.
The conditioningconduit 234s provided at its
upper end with an air inlet port 29 a?ording
passage for air, thereinto from the air-collec
that indicatedat 31, Fig. 2, variably adjustable
circulatory system proper by closure of the proper
outlet opening or openings; in the illustrated
case,.the outlet opening 34. Consequently, when
it is desirable to eliminate used air, such as air
tainted with cooking odors as in thelcase of the
kitchen, the. vent 31 may be opened and the
outlet opening 34 closed. Conditioned air may
then be admitted to such room from the plenum
chamber l8 through the opening 32, the dis
35 tion chamber ll. Passage from the conditioning
charge of'used, tainted air being to the outside
conduit into the plenum chamber l3 may be_ atmosphere through the open vent 31, rather
a?orded the air by an outlet opening 30 at the, than back into the system for recirculation. At
lower end of such conditioning conduit. Ad
such time the air inlet 35, controlling admission
vantageously, such outlet opening 30 forms the ofv air to the system from the outside, may be

that air, forced by suitable air-circulating means
as for instance by the suction fan 3|, to enter
the conditioning conduit 23 through the inlet
port 23, will be forcedv through such thermaliz
45 ing passage 23c in heat exchange relation with
the thermal surfaces of the furnace 23, and will
be discharged into the plenum chamber II as
