Abstract

A room comprise of localized region (10) for air conditioning wherein conditioned air or totally fresh air can be directed to certain region of the room. A path of air flow may comprised of a ceiling air collector/distributor (80) joining with a floor air collector/distributor (41) by a duct (18) having the localized air conditioning region (10) link the floor air collector/distributor to the ceiling air collector/distributor to complete the circuit while maintaining the characteristic of air conditioning specific portion of the room only but not the whole room.

Claims7

Dependent claims

Air conditioning delivery apparatus comprising:

a) a region enclosing a volume of air within a space at least partially defined by an upper surface and a lower surface;
b) an air flow system associated with said region forming one or more air flow loops including;
i) means for redirecting floor air to said region vertically disposed within said space, said means for redirecting floor air located substantially directly beneath said region at said lower surface and further comprising a plurality of downward-facing elongated channel members laid side by side on a supporting surface such that the channels and supporting surface form a plurality of passageways, each of said channel members including a plurality of aperture means on at least one side of the channel member for redirecting air through said region;
ii) at least one air collection means for collecting air from said region;
iii) ducting means for transferring air between said means for redirecting and said air collection means;
iv) means for moving air being located within said one or more air flow loops of said air flow system;
v) means for air temperature adjustment situated within at least one of said air flow loops;
vi) means for fresh air ingress communicating with the air flow system;
wherein said air collection means comprises an overhead hood extending downward from the upper surface, including:
A) a top portion, wherein said top portion forms an envelope joining an aperture in the upper surface, and
B) a flexible lower portion, said lower portion being of a flexible material joined at an upper edge thereof to the top portion with an outer ring and further including:
an outer portion, and a mobile inner portion joined at a lower edge thereof to an inner ring, said inner portion being formed from the lower portion by folding the lower portion inside itself;
and
C) plural lines attached to the inner ring and passing through at least two pulley means located above the lower portion for raising the lower edge to a desired height.
