Abstract

A pre-chill system for reducing the temperature of air entering a cooling system includes a wicking material sheet and a series of frame segments. The frame segments are operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system, each of the series of frame segments including one or more magnets magnetically attachable to the cooling system. A misting system is capable of directing moisture adjacent an outer face of the wicking material sheet. The frame segments are magnetically attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing.

Claims

1. A pre-chill system for reducing the temperature of air entering a cooling system, comprising:

a wicking material sheet;

a series of frame segments, operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system, each of the series of frame segments including one or more magnets magnetically attachable to the cooling system; and

a misting system capable of directing moisture adjacent an outer face of the wicking material sheet;

the frame segments being magnetically attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing;

wherein at least one of the frame segments includes retaining notches for retaining tubes of the misting system.

2. The pre-chill system of claim 1, further comprising a controller operably coupled to the misting system, the controller operable to selectively control when water is supplied to the misting system.

3. The pre-chill system of claim 2, further comprising an operation sensor, operably coupled to the controller, the operation sensor operable to sense movement of the cooling system to enable the controller to control supply of water to the misting system when the cooling system is in operation and to stop the flow of water to the misting system when the cooling system is not in operation.

4. The pre-chill system of claim 3, wherein the operation sensor is operable to sense relative humidity and temperature.

5. The pre-chill system of claim 3, wherein the operation sensor is magnetically attached to the outer casing of the cooling system.

6. The pre-chill system of claim 3, wherein the misting sensor is electronically isolated from the cooling system.

7. The pre-chill system of claim 1, wherein the system can be installed and operated without access to any internal components of the cooling system.

8. A pre-chill system for reducing the temperature of air entering a cooling system, comprising:

a wicking material sheet;

a series of frame segments, operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system; and

a misting system capable of directing moisture to the wicking material;

a controller, coupled to the misting system and being operable to selectively control when water is supplied to the misting system; and

an operation sensor, operably coupled to controller, the operation sensor operable to sense movement of the cooling system to active the controller to supply water to the misting system when the cooling system is operating.

9. The pre-chill system of claim 8, wherein the frame segments include one or more magnets attached thereto, the frame segments being attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing.

10. The pre-chill system of claim 8, wherein the operation sensor is operable to sense relative humidity and temperature.

11. The pre-chill system of claim 8, wherein the operation sensor is electronically isolated from an electrical system of the cooling system.

12. The pre-chill system of claim 8, wherein at least some of the frame segments include retaining notches for retaining tubes of the misting system.

13. A method for reducing the temperature of air entering a cooling system, comprising:

positioning a wicking material sheet in a path along which air enters the cooling system;

securing the wicking material sheet to an outer casing of the cooling system with at least one frame segment, the at least one frame segment including one or more magnets that magnetically engage the outer casing of the cooling system;

sensing motion of the cooling system when the cooling system is in operation;

selectively directing a water mist adjacent an outer face of the wicking material sheet when the cooling system is in operation to thereby cool air passing through the wicking material sheet prior to entering the cooling system, and selectively ceasing application of the water mist when the cooling system is not in operation to.

14. The method of claim 13, wherein sensing motion of the cooling system is accomplished using a motion sensor magnetically coupled to an outer casing of the cooling system.

15. The method of claim 14, wherein the motion sensor is electronically isolated from an electrical system of the cooling system.

16. The method of claim 13, wherein at least one of the frame segments includes retaining notches for retaining tubes of the misting system.

17. The method of claim 13, wherein the method is accomplished without accessing any internal components of the cooling system.
