The outer pipe has a wall provided with at least one nozzle to jet the refrigerant into the space. The nozzle has a jet port. The jet port may allow the refrigerant to jet in a radial direction including at least an axial direction and a circumferential direction of the inner pipe. A shielding plate may be provided ahead of the jet port in a jetting direction such that the refrigerant hitting the shielding plate expands along a surface of the shielding plate in a radial direction.

An icemaking system includes a circulation circuit configured to circulate icemaking solution, at least one icemaker provided in the circulation circuit, a cooling mechanism, a first detector and an adjuster.

The cooling chamber has an inflow port and an exhaust port of solution, and the cooling chamber allows the solution to flow in the cooling chamber. The scraping mechanism scrapes ice generated on an inner surface of the cooling chamber. The cooling mechanism cools the solution in the cooling chamber. The first detector detects whether the inflow port of the cooling chamber has an ice nucleus. The adjuster adjusts a cooling temperature of the solution in accordance with a detection result of the first detector.

A method for solidifying a polar substance, in particular water, is presented which comprises the steps of: providing a coolable, hydrophobic, preferably super-hydrophobic, condensation surface within an interior of a container; partially filling the container with a polar substance, preferably in liquid form, and an immiscible additive, preferably in liquid form, so that the condensation surface remains at least partially unsubmerged; cooling the hydrophobic condensation surface to a temperature T.sub.cond below a solidification temperature T.sub.solid of the polar substance; and removing solidified polar substance from the container.

an ice making system includes a tank that stores a medium to be cooled, an ice making machine that cools the medium and makes ice, a pump that circulates the medium between the tank and the ice making machine, a de-icing mechanism that heats the medium and melts the ice in the ice making machine, and a control device that controls operations of the ice making machine, the pump, and the de-icing mechanism. The ice making machine includes a cooling chamber that cools the medium, an inflow port through which the medium flows into the cooling chamber, and a discharge port through which the medium is discharged from the cooling chamber. The control device activates the de-icing mechanism when a pressure difference between a pressure of the medium at the inflow port and a pressure of the medium at the discharge port exceeds a predetermined value.
