What is an Industrial Chiller?

Date: 12-25-2017

  • Industrial chillers are classified as a refrigeration system that cools a process fluid or dehumidifies air in commercial and industrial facilities.  A chiller will use either a vapor compression or absorption cycle to cool.  Chilled water has a variety of applications from space cooling to process uses. 

     

    Types of Industrial Chillers
    A chiller is rated between one to 1000 tons of cooling energy.  There are three different types of chillers:(1) air, (2) water, and (3) evaporative condensed chiller.  There are four subcategories in each of the above categories for industrial chillers:  (1) reciprocating, (2) centrifugal, (3) screw driven (4) and absorption chillers.  The first three types are mechanical chillers which are powered by electric motors, steam, or gas turbines.  An absorption chiller is powered by a heat source such as steam and uses no moving parts. 

     

    Components of an Industrial Chiller
    The mechanical compression cycle has four basic components through which the refrigerant passes: (1) the evaporator (2) the compressor (3) the condenser (4) the expansion valve.  The evaporator in the chiller will operate at a lower pressure and lower temperature than the condenser.
