Ice machine water guide
An ice machine is a refrigeration machinery that generates ice from a water refrigeration system. The water is continuously distributed to the evaporator, and the compressor operates to keep the evaporator at a low temperature of -10 to -18 °C. The water continuously condenses into an ice layer on the surface of the low-temperature evaporator, when the ice layer condenses to a certain thickness. Turn on the defrost solenoid valve to introduce ice from the evaporator into the ice storage tank, and then proceed to the next cycle.
At present, the domestic ice machine market dominates the domestic ice machine, and the share of imports is relatively small. Major domestic brands include Beijing Changliu, Beijing Lebo, and Changzhou Xueke.
The influent of the ice machine usually requires the use of water that meets the national standard for drinking water hygiene (GB 5749-2006) and a hardness of not more than 450 mg/L of CaCO 3 . Calcium and magnesium ions in hard water will precipitate and form scale, which will damage the pump, evaporator and other components of the ice machine. China's hard water areas are mainly distributed in the Loess Plateau, the North China Plain and the Liaohe River Basin, the western Sichuan and Qinghai-Tibet Plateau, the central and southern Guizhou, and the Inner Mongolia Plateau. Among them, Hebei and Shanxi are serious areas with hard water. Taking Beijing as an example, the hardness of the western and central regions is about 400-450 mg/L CaCO 3 , and the hardness of the southern zone is 450 - 800 mg/L CaCO 3 . Long-term use of such water as influent will greatly reduce the life of the ice machine.
RephiLe's fully automatic softening system can reduce the calcium and magnesium ions in raw water by more than 95%, effectively reducing the hardness of the influent. The fully automatic softening system replaces Ca 2+ and Mg 2+ in raw water with a built-in sodium cation exchange resin to achieve the purpose of softening water. After the resin replacement capacity is saturated, the system automatically regenerates without special maintenance. The automatic softening system can handle up to 1000 L/h, which is far from the water consumption of the ice machine. The treated soft water can not only provide water for the ice machine, but also provide safe and stable water for pure water, distilled water, rotary evaporator, water bath and circulating water pump. For particularly demanding ice machines, RephiLe also offers Direct-Pure RO water purification system, which uses tap water as the influent water to produce RO pure water with a water conductivity of less than 20 μS/cm, which can better meet the ice machine. Waiting for the demand.
