Function of demister and labyrinth in centrifugal chiller
(OP)
Hi to all
I appreciate any responses from our group of experts. Can anybody explain the function of demisters and the labyrinths in the centrifugal chillers.
Thanks in advance

RE: Function of demister and labyrinth in centrifugal chiller
So special devices were developed to remove mist from gas streams. known as mist eliminators, these devices provide a large surface area in a small volume to collect liquid without substantially impeding gas flow. Unlike filters, which hold particles indefinitely, mist eliminators coalesce (merge) fine droplets and allow the liquid to drain back to the oil sump and to further maintain the oil integrity of the oil system. We need to make sure that all the oil used is returned to the oil sump, so a labyrinth seal, which is a mechanical seal that fits around a rotating shaft is installed to prevent the leakage of oil or other fluids

The main drawback with labyrinth seals is that they can't seal if the shaft is not rotating.

True but in a Centrifugal machineat rest the pressures equalize so the leakage is minimal at best.
