Chillers

Liquid coolers (chillers) are increasingly used in a wide range of industries and production. Liquid coolers are an indispensable element in closed circuits for cooling production machines but also for various types of air conditioning systems. Coolers allow you to maintain the right temperature of the coolant fluids in machine tools, electrodes, welding equipment, which rely on efficient heat exchange. Chillers are found in brewing and food processing, in foil packaging, electroplating, electro-mechanical and power industry, footwear, laundries, printers and even in specialized medical technology such as in MRI scans. Principle of operation of the liquid cooler Liquid coolers do not differ from conventional refrigeration systems. Standard features of chilled water chillers are heat exchangers such as evaporators and condensers, compressors, or their entire assembly, thermostatic expansion valve or electronically controlled. The operation of liquid coolers is based on a simple heat transfer process. Generators usually work in closed circuit loops. In simple terms, the refrigerant (pacifier) ​​is pumped into the evaporator, where, by means of fans, the refrigerant exchanges its heat with air or coolant. Then the steam medium arrives at the compressor, where it is heated by compression and then condensed in the condenser. At the end, the refrigerant and the reduced pressure on the expansion valve travel to the evaporator, where the circuit starts again. Essential division of chillers Due to the type of condenser (condenser), chillers are air-cooled and water-cooled. Their construction and principle of operation is similar to each other. When selecting a suitable liquid cooler, we should be guided by both the working condition and the purpose of the device itself. Chillers air-cooled due to their smaller dimensions, they will be used wherever there is not enough space available. Liquid cooled air coolers require the use of additional components such as distribution pumps for cooling liquids, condensers and cooling towers. Liquid chilled water chillers are also much more expensive.
