How are chillers being used in industrial process cooling?

The theory behind industrial cooling circuits is generally well understood: A cooling medium absorbs heat from a process and then needs to transfer that heat out of the system via a combination of refrigeration and/or heat exchangers. This coolant then returns to the heat source and the cycle starts again. Typical cooling media include: Demineralized water, water-glycol mixtures, water-based emulsions, and oil-based emulsions.

Which cooling medium is used where?

Demineralized water is well suited for cooling components and machines. Server racks, frequency converters, and other types of electronic equipment, for example, are often cooled with demineralized water. However, because this cooling medium is highly corrosive, all cooling lines must be made of stainless steel or other non-corrosive materials. Water-glycol mixtures enable the rapid removal of process heat. They are used, for example, for cooling milling spindles. Water-based emulsions are also frequently used to cool spindles and other machine components. Water-based emulsions have a heat capacity that is somewhat lower than that of water-glycol mixtures. As compared with demineralized water, a positive for systems with water-based mixtures/emulsions is that the piping does not require any special corrosion precautions. Oil-based emulsions are sometimes referred to as “cutting oils” and are primarily used as a lubricant in the interface between the chips and a machine tool’s cutting edge. The oil helps to reduce friction and aides in chip flow away from the cutting surface. Cutting oils are also employed as a cooling agent to remove any process-generated heat. The lubrication and cooling of the process can improve the surface finish of machined work. The use of oil emulsions requires pumps that can handle such highly viscous media.
