The principle of the supercooled water dynamic ice making is as follows: the water is cooled to a supercooled state in the supercooler, namely, the water in the supercooled state is lower than the freezing point temperature but does not freeze, after the water flows through the ice slurry generator, the supercooled state of the water is eliminated into an ice water mixture, finally, the water and the ice slurry with higher concentration are separated through the filtering device, wherein the separated water is recycled in the system, and the rest ice is stored in the ice storage tank.

Referring to fig. 4, in one possible embodiment, the de-crystallization device 320 further includes a second heat exchanger tube bundle 325, an inlet end of the second heat exchanger tube bundle 325 is connected to a second inlet 3203 of the de-crystallization device 320, and an outlet end of the second heat exchanger tube bundle 325 is connected to a second outlet 3204 of the de-crystallization device 320; the second heat exchanger tube bundle 325 is in a bent configuration and passes through the first baffle 322 and/or the second baffle 323 at least once. The heat exchange path can be effectively prolonged, and the heat exchange effect can be improved.

In this embodiment, the specific configuration of the decrystallization device 320 is further optimized. Specifically, the crystal removing device 320 is configured as a combined member at least including a casing 321, a first baffle 322, a second baffle 323, a filter 324, and a second heat exchange tube bundle 325, wherein the second heat exchange tube bundle 325 is distributed inside the casing 321 in a serpentine shape, an inlet of the second heat exchange tube bundle 325 is connected to a second inlet 3203, an outlet of the second heat exchange tube bundle 325 is connected to a second outlet 3204, and the second outlet 3204 is located above the second inlet 3203. The refrigerant flows through the crystal removing device 320 through the second heat exchange tube bundle 325, and exchanges heat with supercooled water in the crystal removing device 320, so that the water temperature of supercooled water is increased to a small extent, and ice crystal particles in supercooled water are melted, and meanwhile, the supercooled water is not heated to a large extent.

In one possible embodiment, the ice making module 300 further includes a water replenishing device 340 and a fifth pipe member 350, wherein the water inlet end of the water replenishing device 340 is connected to the cold water outlet 104, and the water outlet end of the water replenishing device 340 is connected to the first inlet 3201 of the crystal removing device 320; the fifth pipe member 350 communicates the water replenishing device 340 and the ice storage device 310, and a fifth valve body 351 is provided on the fifth pipe member 350. By the arrangement, the supply of liquid water in continuous ice making can be ensured, and ice melting operation is convenient.

As shown in fig. 1, as the refrigerating cycle proceeds, water is gradually converted into ice, the ice concentration in the ice storage device 310 is gradually increased, and the water content is gradually decreased. When the ice concentration in the ice storage device 310 reaches a certain amount, the ice crystal content in the cold water flowing out of the outlet end of the ice storage device 310 increases, and if the cold water enters the de-crystallization device 320, the difficulty of de-crystallization of the de-crystallization device 320 increases, and the icing risk of the evaporator 110 increases. Based on this, a water replenishing device 340 is disposed between the ice storage device 310 and the evaporator 110/the de-crystallization device 320, when the ice concentration in the ice storage device 310 is too high, the fifth valve 351 is opened, water is replenished into the ice storage device 310 by the water replenishing device 340, the ice concentration in the ice storage device 310 is reduced, the ice crystal content in the cold water flowing out from the outlet end of the ice storage device 310 is reduced, the water outlet state temperature of the ice storage device 310 is ensured, and the ice making cycle is continuously performed.
