For example, the chilling temperature of supposing cooling space S drops to temperature lower than the phase transition temperature of 0 ℃ (phase transition temperature of water) or liquid L from normal temperature.When carrying out when cooling, want in the temperature (1 ℃ to-5 ℃) that---forms at this ice crystal and be maximized---lower than the brilliant district that forms of the maximum ice of water or form at the temperature of distinguishing lower than the maximum ice of liquid L is brilliant, water or liquid L are remained on supercooled state.
Liquid L evaporates in cooling procedure, makes steam W1 flow in gas Lg (or space) in container C.In the situation that container C is sealed by lid Ck, gas Cg may be because of steam W1 supersaturation.In this embodiment, container C can optionally comprise and covers Ck.Cover Ck if container C comprises, can prevent from flowing directly into from the cold air of cooling space S, prevent that perhaps the temperature of the gas Lg on the Surface L s of the temperature of Surface L s of liquid L or liquid L from reducing because of cold air.
When chilling temperature met or exceeded the brilliant temperature that forms the district of the maximum ice of liquid L, liquid L formed ice crystal nucleus F1 in gas Lg, perhaps formation ice crystal nucleus F2 on the inwall of container C.Otherwise, the contact site condensation of liquid L between the Surface L s of liquid L and the inwall of container C (almost identical with the chilling temperature of cooling space S).The liquid L of condensation can form ice crystal nucleus F3.
For example, when the ice crystal nucleus F1 in gas Lg descends and the Surface L s that passes liquid L when being penetrated in liquid L, liquid L breaks away from supercooled state, and causes that liquid L freezes.
In addition, because ice crystal nucleus F3 contacts with the Surface L s of liquid L, so liquid L breaks away from supercooled state, and cause that liquid L freezes.
As mentioned above, according to the process that forms ice crystal nucleus F1 to F3, when liquid L remains the temperature of distinguishing lower than the brilliant formation of its maximum ice, owing to evaporating from liquid L and being present in freezing of steam on the Surface L s of liquid L and freezing on the inwall of the Surface L s that is adjacent to liquid L of container C, liquid L breaks away from supercooled state.
Fig. 4 shows the view of the process that prevents that in supercooling apparatus according to the present invention ice crystal nucleus from forming.
In Fig. 4, freeze in order to prevent the steam W1 in gas Lg, namely, in order to keep continuously the state of steam W1, the Temperature Setting of the Surface L s of gas Lg or liquid L is become higher than the brilliant temperature that forms the district of the maximum ice of liquid L, preferably, higher than the phase transition temperature of liquid L.In addition, the Temperature Setting of the Surface L s of liquid L is become higher than the brilliant temperature that forms the district of the maximum ice of liquid L, preferably, higher than the phase transition temperature of liquid L, thereby even the Surface L s of liquid L contacts with the inwall of container C, can prevent that also the Surface L s of liquid L from freezing.
Therefore, the liquid L in container C is keeping supercooled state lower than its phase transition temperature or brilliant the formation at the temperature of distinguishing of its maximum ice.
Fig. 5 is the chart of supercooled state that the water of Fig. 4 is shown.The chart of Fig. 5 shows in the situation that liquid L is the temperature that water is measured under the principle of Fig. 4.
In Fig. 5, line I is the chilling temperature curve of cooling space S, and line II is the temperature curve of the lip-deep gas Lg (air) of water in container C, and line III is the temperature curve of the outer surface of container C.The temperature of the outer surface of container C equals the temperature of the water in container C substantially.
As shown in Figure 5, in the scope of chilling temperature in the situation that approximately-13 ℃ to approximately-14 ℃ (referring to line I), when the lip-deep gas Lg of water in container C keeps about 4 to 6 ℃ when---this temperature is higher than the brilliant temperature that forms the district of the maximum ice of water---, water in container C remains on approximately-11 ℃, lower than the brilliant temperature that forms the district of the maximum ice of water, and stably maintain the supercooled state that keeps liquid within longer a period of time.
