Water-cooled direct freezing in the electroplating (oxidation) industry refrigeration principle: the water in the cooling tower bottom basin is sent to the condenser of the chiller through the water pump to cool the condenser, and then flows back to the cooling tower to spray down and through the cooling tower top. The fan on the upper part cools down the water and then flows back to the bottom of the cooling tower, so that it runs back and forth.

The effect of chiller cooling is very good. Now it is used in many industries. What is the difference between direct freezing and indirect freezing in the electroplating industry?

Water-cooled direct freezing in the electroplating (oxidation) industry refrigeration principle: the water in the cooling tower bottom basin is sent to the condenser of the chiller through the water pump to cool the condenser, and then flows back to the cooling tower to spray down and through the cooling tower top. The fan on the upper part cools down the water and then flows back to the bottom of the cooling tower, so that it runs back and forth. The condenser dissipates heat while the refrigerant inside is liquefied, and then flows into the evaporator in the cold gun to evaporate, and absorbs heat when evaporating, so that the sulfuric acid (tank) in the cold gun is cooled, and the sulfuric acid after cooling is transported by the water pump. To the plating (oxidation) tank, this is a cyclic process.



Water-cooled indirect freezing The refrigeration principle in the electroplating (oxidation) industry: the water in the bottom tank of the cooling tower is sent to the condenser of the chiller through a water pump to cool the condenser. When it flows back into the cooling tower and sprays down, the water is cooled by the fan on the top of the cooling tower, and then flows back to the bottom of the cooling tower, so that it runs again and again. The condenser dissipates heat while the refrigerant inside is liquefied, and then flows into the evaporator in the water tank for evaporation, and absorbs heat during evaporation, thereby cooling the water in the water tank, and the cooled water is transported to the heat exchanger through the water pump (middle) Separating, one side of the water, one side of sulfuric acid, and then cooling the sulfuric acid by the process of heat transfer, is such a cyclic process. The advantage of this product is that it is easy to install, the service life is relatively longer than that of direct freezing, and the acid and alkali are not easy to corrode the chiller.
