A wet surface air cooling system is disclosed and includes a primary cooling unit having a bundle of heat exchanger tubes. Water is directed over the bundle of heat exchanger tubes and is collected in a collection basin. A secondary cooling tower is provided and a closed circulatory loop draws a portion of the water from the collection basin and directs the water to the secondary cooling tower to increase the cooling capacity of the system. The secondary cooling tower is rendered operative automatically upon sensing a particular temperature of the water in the circulation system of the primary cooling unit. |

DETAILED DESCRIPTION OF THE INVENTION Referring to the FIGURE in greater detail, a wet surface air cooling system is illustrated and generally designated 10.
The system includes a primary cooling unit, generally designated 12, and a secondary cooling unit, generally designated 14.
The primary cooling unit 12 includes heat exchanger means 16, such as a bundle of heat exchanger tubes, and a spray head, generally designated 18, for directing water downwardly onto the bundle of heat exchanger tubes.
A shell 20 defines a collection basin 22 for collecting water directed over the heat exchanger tubes.
A pump 24 draws water from collection basin 22 and recirculates the water through a line 26 to spray head 18.
A fan 28, disposed within a flue 30, discharges air from the interior of shell 20 and causes an airstream from atmosphere past the heat exchanger tubes.
The airstream is indicated by arrows A-D.
The flue can comprise a prismatic stack, as is known.
At this point it should be noted that primary cooling unit 12 is somewhat conventional and its capacity is generally determined by the size of the bundle of heat exchanger tubes and the volume of air which is passed over the tubes for evaporation purposes.
These units are relatively expensive, and increasing the capacity of such a unit requires more heat transfer surface and correspondingly increasingly expensive equipment, such as larger or more fans, larger motors, gears, etc.
to force a higher volume of air through the unit.
Conventionally, such units are designed for a predetermined full cooling load, such as maximum summer wet bulb temperatures.
However, such maximum load requirements occur only approximately 1 to 5 percent of normal summer hours.
Therefore, such units as described above are relatively inefficient if they are designed to accomodate maximum cooling loads for a given locality.
In essence, increasing the capacity of such units normally requires more heat exchanger surface in addition to more air moving equipment, along with increased energy consumption
