- 2. The livestock cooling system of claim 1 further comprising means for injecting water droplets into the air stream of each fan.
- 3. The livestock cooling system of claim 1 further comprising a clock connected to the oscillation means.
- 4. The livestock cooling system of claim 3 wherein the clock is contained within a local control panel.
- 5. The livestock cooling system of claim 1 wherein the rotational position of each fan is sensed by a position indication device.
- 6. The livestock cooling system of claim 5 wherein the position indication device produces a signal in response to the rotational position of the fan.
- 7. The livestock cooling system of claim 1 wherein the oscillation means comprises an oscillation motor connected to the plurality of fans by a linkage means.
- 8. The livestock cooling system of claim 7 wherein the rotational position of each fan is sensed by a position indication device mounted at the oscillation motor.
- 9. The livestock cooling system of claim 2 wherein the means for injecting water droplets into the air stream of each fan comprises a mist ring attached to each fan and water is delivered to each mist ring through a high pressure water line.
- 10. The livestock cooling system of claim 9 further comprising means for adjusting the flow rate of water droplets injected into the air stream of each fan.
- 11. The livestock cooling system of claim 10 wherein the means for adjusting the flow rate of water droplets injected into the air stream of each fan comprises a pump connected to the high pressure water line, the speed of the pump being controlled by a variable frequency drive.
- 12. A livestock cooling system comprising:
(a) a plurality of fan support members; (b) a plurality of fans, each fan creating an air stream and each fan rotatably coupled to a fan support member; (c) oscillation means connected to each fan for rotating the fan through a plurality of rotational positions, the plurality of rotational positions defining an arc of rotation, said oscillation means causing each fan to be at the same rotational position at the same time; and (d) means for injecting water droplets into the air stream of each fan.
- 13. The livestock cooling system of claim 12 further comprising timing means connected to the oscillation means whereby each fan oscillates through the arc of rotation at the same time each day.
- 14. The livestock cooling system of claim 12 wherein the means for injecting water droplets into the air stream of each fan comprises a mist ring attached to each fan and water is delivered to each mist ring through a high pressure water line.
- 15. The livestock cooling system of claim 14 further comprising means for adjusting the flow rate of water droplets injected into the air stream of each fan.
- 16. The livestock cooling system of claim 15 wherein the means for adjusting the flow rate of water droplets injected into the air stream of each fan comprises a pump connected to the high pressure water line, the speed of the pump being controlled by a variable frequency drive.
- 17. A livestock cooling system comprising:
(a) a plurality of fan support members; (b) a plurality of fans, each fan creating an air stream and each fan rotatably coupled to a fan support member; (c) oscillation means connected to each fan for rotating the fan through a first plurality of rotational positions and for rotating the fan through a second plurality of rotational positions, the first plurality of rotational positions defining a first arc of rotation and the second plurality of rotational positions defining a second arc of rotation, said oscillation means causing each fan to be at the same rotational position at the same time; and (d) means for injecting water droplets into the air stream of each fan.
- 18. The livestock cooling system of claim 17 further comprising timing means connected to the oscillation means whereby each fan oscillates through the first arc of rotation at the same time each day and each fan oscillates through the second arc of rotation at the same time each day.
- 19. The livestock cooling system of claim 17 wherein the means for injecting water droplets into the air stream of each fan comprises a mist ring attached to each fan and water is delivered to each mist ring through a high pressure water line.
- 20. The livestock cooling system of claim 19 further comprising means for adjusting the flow rate of water droplets injected into the air stream of each fan.
- 21. The livestock cooling system of claim 20 wherein the means for adjusting the flow rate of water droplets injected into the air stream of each fan comprises a pump connected to the high pressure water line, the speed of the pump being controlled by a variable frequency drive.
