The refrigeration principle of Jimes chiller direct cooler in the electroplating (oxidation) industry

There are two types of chillers: air-cooled chillers and water-cooled chillers. Water cooled chillers are referred to differently based on their compressor, structure, or cooling temperature, such as water-cooled screw chillers, water-cooled box chillers, water-cooled low-temperature chillers, etc. Each chiller has its own unique characteristics. For industries such as electroplating, electrophoretic coating, electroplating production lines, anodizing, etc., cooling is aimed at the plating solution inside the plating tank. There are two cooling methods for the electroplating industry using water-cooled chillers: direct cooling and indirect cooling.

The refrigeration principle of water-cooled chillers and direct coolers in the electroplating (oxidation) industry

The water in the bottom basin of the cooling tower is pumped to the condenser of the industrial chiller to cool it down, and then flows back to the cooling tower for spraying. When it goes down, the water is cooled by the fan on the top of the cooling tower and flows back to the bottom basin of the cooling tower, and this cycle continues. At the same time as the condenser dissipates heat, the refrigerant inside liquefies and flows into the evaporator inside the cold gun for evaporation. During evaporation, heat is absorbed, which cools the sulfuric acid (tank solution) in the cold gun. After cooling, it is transported to the electroplating (oxidation) tank through a water pump, and this is a cyclic process.
