How Industrial Chillers Handle Temperature

Date:Jan 08, 2019

The temperature of the industrial chiller is controlled by the compressor. The main cause of the temperature change is the refrigerant inside the compressor. The refrigerant is compressed by the compressor into the condenser for heat exchange to become a low-temperature and high-pressure gas, and then through the capillary to the cold-discharge tube. The liquid to be cooled is subjected to heat exchange, and after the heat exchange is completed, the refrigerant becomes a high-temperature and high-pressure gas and returns to the compressor. Generally, the temperature of cold water in industrial chillers is controlled by a compressor, and the compressor controls the refrigeration by controlling the refrigerant. In fact, temperature control has nothing to do with your refrigeration, just an indicator.


The chiller is applied to the cooling of plastic processing machinery forming molds, which can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, so that the products do not shrink or deform, facilitate the demoulding of plastic products, accelerate the product stereotype, and thus The earth improves the production efficiency of plastic molding machines. The chiller is used in CNC machine tools, coordinate boring machines, grinding machines, machining centers, combination machine tools, and 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 lines, anodizing, etc. are all cooled for the plating solution inside the plating bath. How to choose a chiller? There are two cooling methods, direct cooling and indirect cooling.


Water-cooled chiller directly freezes 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 industrial chiller through the water pump to cool the condenser, and then flows back to the cooling tower to pass through the spray. The fan on the top of the cooling tower cools 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.
