Industrial chillers

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,

(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)  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.
