Ice making artifact-calcium chloride

Although calcium chloride itself does not have a refrigeration effect, it plays an important cooling role in the refrigeration system. The secondary refrigerant relies on sensible heat to carry cooling capacity and is an intermediate medium used to transfer cooling capacity in indirect refrigeration systems. It is cooled by the refrigerant in the evaporator and then sent to the cooling equipment. It absorbs the heat of the object or space being cooled and then returns to the evaporator to be cooled again.

Such cycle; to achieve the purpose of refrigeration. It is widely used in ice cream factories, ice cream factories, ice warehouses, etc. for ice making and condensation.

In our daily life, we often use water to achieve a cooling effect. For example, when we were children, in the summer we would soak watermelons in cold well water to cool down. Water is our common universal refrigerant. But water can only be used in conditions above 0°C. When required to be below 0°C, sodium chloride aqueous solution, magnesium chloride aqueous solution, and calcium chloride aqueous solution are generally used. Because the freezing point of sodium chloride is generally -15℃; the freezing point of magnesium chloride can reach -30℃; the freezing point of calcium chloride can even reach -50℃ without freezing. A professional description: Calcium chloride aqueous solution is an intermediate medium used to transfer refrigeration capacity in indirect refrigeration systems, and is also called the second refrigerant - secondary refrigerant. It is cooled by the refrigerant in the evaporator and then sent to the cooling equipment. It absorbs the heat of the object or space being cooled and then returns to the evaporator to be cooled again.
