Abstract
Abstract An air-conditioning system for a building including a diffuser built into the floor around the periphery of the building''s exterior walls to supply air whose humidity, temperature, and purity has been precisely regulated into the room. A tapered duct supplies the air to the diffuser for constant flow through the diffuser at every point along the length of its outlet. In one embodiment, the diffuser is formed as part of a concrete slab floor and provides a screed rail for the finishing of this floor. In another embodiment, the diffuser is built into a wooden floor and forms an integral structural part thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
An air-conditioning system for a building having a poured concrete floor and a plurality of exterior walls, comprising a source of conditioned air, a supply duct extending from said source and including an elongated discharge portion extending below the top of said floor and continuously adjacent at least one of said exterior walls, an elongated diffuser extending within the floor substantially directly above said duct and parallel to said one exterior wall, said diffuser including inner and outer panel members disposed in laterally spaced relation to define a discharge slot extending substantially continuously along said one exterior wall and from said duct through said floor to produce an upward flow of conditioned air continuously along said one exterior wall, and means disposed at longitudinally spaced intervals along said diffuser for rigidly connecting said inner and outer panel members and for forming structural ties between said floor and said one exterior wall.
Claim 2
Dependent Claim
151 words
An air-conditioning system for a building having a poured concrete floor and a plurality of exterior walls, comprising a source of conditioned air, a supply duct extending from said source and including an elongated discharge portion extending below the top of said floor and continuously adjacent at least one of said exterior walls, an elongated diffuser extending within the floor substantially directly above said duct and parallel to said one exterior wall, said diffuser including inner and outer panel members disposed in laterally spaced relation to define a discharge slot extending substantially continuously along said one exterior wall and from said duct through said floor to produce an upward flow of conditioned air continuously along said one exterior wall, and means disposed at longitudinally spaced intervals along said diffuser for rigidly connecting said inner and outer panel members and for forming structural ties between said floor and said one exterior wall.
Claim 3
Dependent Claim
35 words
An air-conditioning system as defined in claim 1 wherein an adjustable damper is mounted on said diffuser and is adapted to slide across said discharge slot to vary the rate of flow through said slot.
Claim 4
Dependent Claim
38 words
An air-conditioning system as defined in claim 2 wherein said adjustable damper includes a slide, a support for said slide, and means connecting said slide to said support for horizontal movement of said slide across said discharge slot.
Claim 5
Dependent Claim
42 words
An air-conditioning system as defined in claim 1 wherein said supply duct is tapered so that its cross-sectional area gradually decreases from said source to produce a substantially constant flow of air along the entire length of said slot in said diffuser.
Claim 6
Dependent Claim
26 words
An air-conditioning system as defined in claim 1 wherein said diffuser includes an abutment walL adjacent said slot adapted to have the floor covering abutted thereto.
Claim 7
Dependent Claim
30 words
An air-conditioning system as defined in claim 1 wherein said duct is defined between parallel rows of concrete blocks and has a bottom surface which slopes downwardly toward said source.
Claim 8
Dependent Claim
41 words
An air-conditioning system as defined in claim 1 wherein a plurality of longitudinally disposed adjustable dampers are mounted on said diffuser adjacent said discharge slot to provide for varying the flow rate of air through said slot at longitudinally spaced intervals.
Claim 9
Dependent Claim
49 words
An air-conditioning system as defined in claim 1 wherein said inner and outer members of said diffuser each includes vertically spaced horizontal flanges, and said lower flanges are effective to position said diffuser so that said upper flanges are positioned substantially flush with the top surface of said floor.
Claim 10
Dependent Claim
21 words
An air-conditioning system as defined in claim 1 wherein said connecting means comprise longitudinally spaced sets of upper and lower bars.
Claim 11
Dependent Claim
26 words
An air-conditioning system as defined in claim 1 wherein said diffuser and said slot extend substantially continuously around all of the exterior walls of said building.
Claim 12
Dependent Claim
47 words
An air-conditioning system as defined in claim 1 wherein said diffuser has a flat horizontal surface on the inner member thereof, and said floor has its corresponding exterior peripheral edge supported by said diffuser with said horizontal surface serving as a screed rail for smoothing the concrete.
