can someone explian how steam is used to create chilled water.

thanks

You could drive the compressor with a steam turbine or use an absorbtion machine.

If you don't mind doing a little reading this is a good explanation:

Are you looking for an explanation on absorption chillers; how they work? Or are you looking for a way to create chilled water with steam?

 

[asme3470]

looking to see how they work

also here is a link on steam turbine chillers

These are not generally recommended unless you are using waste heat to make steam or you can get steam real cheap due to the inefficiencies of these type of machines.

I just designed a project with a Yazaki hot water absorption units using 2-30ton units.

I'm an old hand and absorption chillers were used mostly in hospitals where they had med temp steam (220F and up) all the time and sizes were from 100 tons on up which made them impractical for anything but large cooling loads with campus-style heating plants.

Cogeneration has caused manufacturers to produce small tonnage units which will operate from 150F-220F. Absorption now can be used for local small loads and absorption has lots of advantages.

Attached link describes how absorption cooling works:

If you have lots of low pressure steam you can use a vacuum chiller. Rummage around on this site; they have this type equipment.
