Chilled water is produced by an evaporative cooling process. The chilled water is then circulated through a liquid-air heat exchanger to produce a primary air supply of cool-dry air wherein no water is introduced into the cool dry air stream. The primary air supply can be used to cool a space, such as an office, where low humidly is desirable. Additionally, the cool, wet air which is a byproduct of the water-cooling phase can be used as a secondary air supply. The secondary air supply can be used to cool a space where higher humidity is tolerated, such as a warehouse, a garage, a barn, etc. The indirect evaporative cooling system can also be used in conjunction with an air conditioning system to reduce operating costs and increase efficiency.

1. A dual usage cooling system, comprising: a wet portion comprising an evaporative cooler that chills a supply of liquid and outputs a secondary air supply cooled by the evaporative cooler to a first room; anda heat exchanger which uses the chilled liquid to transfer heat from air inputted into the heat exchanger thereby cooling the air, the cooled air output as a primary air supply to a second room;wherein the first room and the second room are situated in different parts of the same building;wherein the primary air supply has a substantially lower moisture level than the secondary air supply;wherein the heat exchanger includes a coil wherein the chilled liquid passes through and the inputted air contacts outer surfaces thereof; andwherein the wet portion further comprises a housing, a plurality of drifts and a water disperser having at least three water dispersing heads capable of producing mist; wherein each of the drifts extend from the ceiling of the housing to just above the water level of a reservoir rising from the floor of the housing, and the water disperser is disposed between a pair of the drifts and the at least three water dispersing heads are situated at different heights to each other relative to the floor. 2. The dual usage cooling system of claim 1, wherein the liquid is water. 3. The dual usage cooling system of claim 1, wherein the primary air supply has substantially the same moisture level as the air inputted into the heat exchanger. 4. The dual usage cooling system of claim 1, further comprising an opening for returning air to the heat exchanger. 5. The dual usage cooling system of claim 1, further comprising a pump which circulates the liquid. 6. The dual usage cooling system of claim 1, wherein the coil includes an anti-siphon loop that keeps the liquid in the coil while the cooling system is not running. 7. The dual usage cooling system of claim 1, wherein an outside water line includes a view filter allowing a user to visually inspect the filter. 8. The dual usage cooling system of claim 1, wherein an air conditioning system is installed for the first room. 9. The dual usage cooling system of claim 8, wherein the cooling system is controlled according to preset values for one or more of dry temperature and relative humidity. 10. The dual usage cooling system of claim 9 wherein the air conditioning system is further controlled by activating the air conditioning system according to a preset value for carbon dioxide. 11. A system for cooling at least a portion of a building, the building including at least a first room and a second room; comprising: a two-stage indirect evaporative cooler comprising (a) a direct evaporative cooler that chills a supply of liquid and produces a secondary air supply cooled by the evaporative cooler, and (b) a heat exchanger comprising a coil wherein the chilled liquid passes through and air inputted into the heat exchanger contacts outer surfaces thereof thereby cooling the air, the cooled air used as a primary air supply;wherein the primary air supply has a substantially lower moisture level than the secondary air supply;a first duct attached to a first port of the two-stage indirect evaporative cooler and extending to a first opening to the first room, the first duct carrying air of the primary air supply to the first room;a second duct attached to a second port of the two-stage indirect evaporative cooler and extending to a second opening in the second room, the second duct carrying air of the secondary air supply to the second room;an air conditioning system having an air supply connected to the first room; andan a controller that turns the air conditioning system on based on preset values for temperature and carbon dioxide level;wherein the direct evaporative cooler further comprises a housing, a plurality of drifts and a water disperser having at least three water dispersing heads capable of producing mist; wherein each of the drifts extends from the ceiling of the housing to just above the water level of a reservoir rising from the floor of the housing, and the water disperser is disposed between a pair of the drifts and the at least three water dispersing heads are situated at substantially different heights to each other relative to the floor. 12. A system, comprising: the cooling system of claim 11, whereinan air conditioning system having an air supply is connected to the first room; andthe cooling system is activated to supplement the air conditioning system only when one or more predetermined threshold value is reached. 13. The system of claim 12, wherein the air conditioning system is activated based on preset values for one or more of dry temperature, relative humidity level, and carbon dioxide level. 14. The system of claim 12, wherein the air conditioning system is activated based on a preset value for carbon dioxide level. 15. The system of claim 11, wherein the two-stage indirect evaporative cooler is situated on a roof of the building.
