Abstract

Abstract An apparatus for productively utilizing the heat from waste liquids discarded by industrial plants, such as power plants, for heating and cooling buildings, such as, greenhouses, and to prevent thermal pollution of bodies of water, such as rivers and lakes, into which the waste liquid is ultimately discharged at a low temperature. For heating a building, the heated liquid is discharged directly onto the building roof at the ridge thereof to flow down the sloping roof sides and is then deflected against the side walls of the building for heating the roof and said walls. The liquid is then collected in troughs for recycling through the industrial plant and back to the apparatus, or may be discharged to waste. For cooling the building the heated liquid is discharged by the apparatus upwardly from above the roof to effect evaporative cooling of the droplets. The cool liquid falling on the roof flows down its sloping sides for cooling the building, and is thereafter cascaded over louvers for recooling the liquid, heated by contact with the roof, before the liquid is discharged into the trough from which it can be recycled or carried off to waste.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 73 words
An apparatus for heating and cooling a building comprising a conduit system for receiving a heated liquid from a supply source, a plurality of spray nozzles constituting the outlet of the conduit system and disposed above the longitudinal extent of the sloping roof of a building, and means adjustably positioning the nozzles to face either upwardly or downwardly whereby the liquid discharged therefrom onto the roof will either cool or heat the roof.
Claim 2
Independent Claim 73 words
An apparatus for heating and cooling a building comprising a conduit system for receiving a heated liquid from a supply source, a plurality of spray nozzles constituting the outlet of the conduit system and disposed above the longitudinal extent of the sloping roof of a building, and means adjustably positioning the nozzles to face either upwardly or downwardly whereby the liquid discharged therefrom onto the roof will either cool or heat the roof.
Claim 3
Dependent Claim 77 words
An apparatus as in claim 1, wherein said conduit system includes a header pipe disposed longitudinally above a topmost portion of the roof, means swivelly supporting said header pipe, said spray nozzles being supported by, communicating with and extending laterally from the header pipe, and said means adjustably positioning the nozzles comprising means for rotating the header pipe a half revolution for moving the nozzles from positions projecting upwardly to positions projecting downwardly from the header pipe.
Claim 4
Dependent Claim 47 words
An apparatus as in claim 2, wherein said means adjustably positioning the nozzles includes a power source having a reciprocably movable part, and a rack and pinion means connecting said movable part to the header pipe for oscillating the header pipe through an arc of approximately 180*.
Claim 5
Dependent Claim 54 words
An apparatus as in claim 1 and said means for cooling the liquid discharging from the roof comprising an adjustable baffle disposed beneath an eave of the roof for receiving and deflecting the heated liquid from the roof against a side wall of the building for heating the wall and for cooling the liquid.
Claim 6
Dependent Claim 25 words
An apparatus as in claim 1 and said means for cooling the liquid discharging from the roof comprising louvers over which the liquid is cascaded.
Claim 7
Dependent Claim 36 words
An apparatus as in claim 5 and means for receiving and conveying the cooled liquid back to the supply source or to the waste including a foundation member having a channel into which the liquid discharges.
Claim 8
Dependent Claim 69 words
An apparatus as in claim 1, comprising a gutter, means adjustably positioning the gutter in an extended position for receiving the liquid discharging from the roof or in a retracted position beneath the roof, a discharge conduit leading from the gutter, a liquid reservoir contained in the building and connected to the discharge conduit, and means for controlling the discharge of the liquid from the reservoir into the building.
Claim 9
Dependent Claim 24 words
An apparatus as in claim 1, wherein said conduit system includes a pump for supplying the heated liquid under pressure to the spray nozzles.
Claim 10
Dependent Claim 16 words
An apparatus as in claim 1, and means for cooling the liquid discharged from the roof.
Claim 11
Dependent Claim 30 words
An apparatus as in claim 1, and means for receiving and conveying the liquid back to the supply source for reheating and recycling or for discharging the liquid to waste.
