Abstract

A system and method for cooling an air supply to a building. The system employs at least one stand alone cooling tower connected to either one stratified storage tank or multiple storage tanks. The water can be cooled during the cooler night time hours and stored for subsequent day time use.

Claims

received by the International Bureau on 13 July 2009 (13.07.2009)
WHAT IS CLAIMED IS:
An interconnected system for cooling the air supply to a building, the system comprising:
(a) a heat exchange element configured to receive cooled water and positioned in an air supply flow;
(b) a duct, a fan, and at least one bypass louver for forcing the air supply over the heat exchange element;
, (c) pump means for circulating water through the system;
(d) at least one cooling tower; and
(e) storage means selected from at least one stratified storage tank or at least two storage tanks; wherein the cooling tower is operated at night to produce cooled water that is stored in at least one of the storage tanks for provision to the heat exchange element for cooling the air supply during the day, the heat exchange element discharging warmed water to at least one of the storage tanks for storage and feeding to the cooling tower for cooling at night.
The system of claim 1 wherein the system is interconnected by conduits having valve means for selectively diverting the flow of water between components of the system.
The system of claim 1 wherein the storage means comprises at least one stratified storage tank.
The system of claim 1 wherein the storage means comprises at least two storage tatiks, one storage tank being used for storing cooled water and one storage tank being used for storing warmed water.
The system of claim 1 further comprising a second heat exchange element in series with the first heat exchange element, the second heat exchange element being interconnected to the system by conduits having valve mea s.

(a) cooling water during the night using at least one cooling tower;
(b) storing the cooled water in storage means selected from at least one stratified storage tank, or one of two storage tanks;
(c) during the day, selectively forcing the air supply across a heat exchange element, the heat exchange element being supplied with cooled water from either me stratified storage tank, or rae one of two storage tanks;
(d) storing warmed water being discharged from the heat exchange element in me stratified storage tank, or the second of two storage tanks until night; arid
(e) repeating steps (a) to (d) for at least one additional cycle.
An interconnected system for cooling the interior of a building, the system comprising:
(a) a heat exchange element selected from a chilled slab, a chilled ceiling panel, or a chilled beam, and disposed within the interior of the building;
(b) pump means for circulating water through the system;
(c) at least one cooling tower; and
(d) storage means selected from at least one stratified storage tank or at least two storage tanks; wherein the cooling tower is operated at night to produce cooled water that is stored in at least one of the storage tanks for provision to the heat exchange element for cooling during the day, the heat exchange element discharging warmed water to at least one of the storage tanks for storage and feeding to the cooling tower for cooling at night.
