1. When the frozen water in the food workshop is a pure water medium, when the water temperature is required to be 0 degrees Celsius or minus 10 degrees Celsius, we should pay attention to the selection of units. Generally, frozen water will not freeze at 0°C. When the unit stops working, we should not stop the chilled water pump immediately. Let the chilled water circulate for about 2 minutes before turning off the chilled water pump (to prevent freezing of the chilled water).
2. When the frozen water requirement of the food workshop is minus 5℃ or 10℃, we should pay attention to that the frozen water medium is still pure water. When the temperature of the frozen water exceeds 0℃, serious freezing will occur. What should we do when? It is necessary to use the plate exchange for exchange. The chilled water and medium of the unit are chemical potions. When the temperature of our chemical potion is minus 10℃, the temperature of the pure water can directly reach 0℃, the chemical potion in the unit is not It is completely separated from the pure water (frozen water) in the food workshop, or it can be said to be two kinds of irrelevant liquids.
