The temperature of the industrial chiller is controlled by the compressor. The main cause of temperature change is the refrigerant in the compressor. The refrigerant is compressed into the condenser by the compressor to exchange heat into a low-temperature and high-pressure gas, and then passes through the capillary tube to the cold exhaust pipe. The liquid to be refrigerated performs heat exchange. After the heat exchange is completed, the refrigerant becomes a high-temperature and high-pressure gas and then returns to the compressor. Generally, the temperature of cold water in industrial chillers is controlled by the compressor, and the compressor controls the refrigeration by controlling the refrigerant. In fact, temperature control has nothing to do with your refrigeration, it just serves as an indicator.
The chiller is applied to the cooling of the molding die of plastic processing machinery, which can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, make the products do not shrink or deform, facilitate the demolding of plastic products, and accelerate product shaping. Greatly improve the production efficiency of plastic molding machines. Water chillers are used in CNC machine tools, coordinate boring machines, grinders, machining centers, modular machine tools, as well as various types of precision machine tool spindle lubrication and hydraulic system transmission medium cooling, which can accurately control the oil temperature, effectively reduce the thermal deformation of the machine tool, and improve the machine tool Precision.
For electroplating, electrophoretic coating, electroplating production line, anodizing, etc., the electroplating solution in the electroplating bath is cooled. How to choose a chiller? There are two cooling methods, direct cooling and indirect cooling.
The principle of direct freezing of water-cooled chillers in the electroplating (oxidation) industry: The water in the bottom basin of the cooling tower is delivered to the condenser of the industrial chiller through a water pump to cool the condenser, and then flows back into the cooling tower when sprayed down. The fan on the top of the cooling tower cools the water and then flows back to the bottom basin of the cooling tower, and it runs again and again. The condenser radiates heat while the refrigerant inside is liquefied, and then flows into the evaporator in the cold gun to evaporate, and the heat is absorbed when evaporating, so that the sulfuric acid (tank liquid) in the cold gun is cooled, and the cooled sulfuric acid is transported by the water pump To the electroplating (oxidation) tank, it is such a cyclic process.
The principle of indirect freezing of water-cooled chillers in the electroplating (oxidation) industry: The water in the bottom basin of the cooling tower is transported to the condenser of the industrial 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 basin of the cooling tower, and 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 to evaporate. When evaporating, it absorbs heat, so as to cool the water in the water tank. The cooled water is delivered to the heat exchanger (the middle Separate, water and sulfuric acid at the same time, and then through the process of heat transfer to cool the sulfuric acid, it is 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 acid and alkali are not easy to corrode. Chiller.
