[ EN ]

WHAT IS CLAIMED IS:

1. A method of ice making comprising:

delivering an emulsion to an oleophilic surface of a heat exchanger;

forming an oil layer on the oleophilic surface of the heat exchanger from oil in the emulsion;

growing ice on the oil layer from water in the emulsion; and

harvesting the ice.

2. The method of ice making of claim 1, further comprising: curtailing the delivering of the emulsion to the oleophilic surface of the heat exchanger; and

subcooling the ice on the oil layer after curtailing the delivering of the emulsion to the oleophilic surface of the heat exchanger.

3. The method of ice making of claim 1, wherein delivering the emulsion to the oleophilic surface of the heat exchanger includes flowing the emulsion down the oleophilic surface of the heat exchanger.

4. The method of ice making of claim 1, wherein harvesting the ice utilizes gravity such that the ice falls away from the oleophilic surface of the heat exchanger.

5. The method of ice making of claim 1, further comprising pumping the emulsion from an emulsion tank to deliver the emulsion to the oleophilic surface of the heat exchanger.

6. The method of ice making of claim 5, further comprising returning a portion of the emulsion to the emulsion tank after delivering the emulsion to the oleophilic surface of the heat exchanger.

7. The method of ice making of claim 6, further comprising delivering additional water to the emulsion tank.

8. The method of ice making of claim 1, further comprising forming the emulsion through combining oil and water.

9. The method of ice making of claim 8, wherein forming the emulsion through combining the oil and the water includes utilizing suction in an emulsion tank to bring the oil and the water together to form the emulsion.

10. The method of ice making of claim 8, wherein forming the emulsion through combining the oil and the water includes pumping the water to an ejector that forms suction with respect to the oil to bring the oil and the water together to form the emulsion.

11. The method of ice making of claim 8, wherein forming the emulsion through combining the oil and the water includes utilizing a mechanical mixer to combine the oil and the water.

12. The method of ice making of claim 1, wherein the oleophilic surface of the heat exchanger is vertically oriented such that the emulsion flows down the oleophilic surface of the heat exchanger .

13. The method of ice making of claim 1, wherein the oleophilic surface of the heat exchanger includes at least PTFE, FEP, Polyethylene, Nylon, Acetal, PVDF,

Silicone, or an oleophilic plastic.

14. The method of ice making of claim 1, wherein the oil includes at least a hydrocarbon oil, a fluorocarbon oil, and a silicone oil.

15. An ice making system comprising;

an emulsion tank; and

a heat exchanger that includes an oleophilic surface configured such that an emulsion from the emulsion tank flows down the oleophilic surface to form an oil layer on the oleophilic surface and to form ice on the oil layer.

16. The ice making system of claim 15, further comprising a pump that delivers the emulsion from the emulsion tank to the oleophilic surface of the heat exchanger.

17. The ice making system of claim 15, further comprising a water tank coupled with the emulsion tank to provide water to the emulsion tank.

18. The ice making system of claim 16, further comprising a suction port positioned with respect to the emulsion tank and the pump to remove water and oil from the emulsion tank to form the emulsion delivered to the oleophilic surface of the heat exchanger.

19. The ice making system of claim 16, further comprising an ejector positioned with respect to the emulsion tank and the pump to mix water and oil from the emulsion tank to form the emulsion delivered to the oleophilic surface of the heat exchanger.

20. The ice making system of claim 16, further comprising a mixer positioned with respect to the emulsion tank and the pump to mix water and oil from the emulsion tank to form the emulsion delivered to the oleophilic surface of the heat exchanger.

21. The ice making system of claim 15, further comprising the emulsion, wherein the emulsion includes water and oil.

22. The ice making system of claim 15, wherein the oleophilic surface of the heat exchanger is vertically oriented such that the emulsion flows down the oleophilic surface of the heat exchanger.

23. The ice making system of claim 15, wherein the oleophilic surface of the heat exchanger includes at least PTFE, FEP, Polyethylene, Nylon, Acetal, PVDF, Silicone, or an oleophilic plastic.

24. The ice making system of claim 15, wherein the oil includes at least a hydrocarbon oil, a fluorocarbon oil, and a silicone oil.
