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.
