The question begs a "how would you do this or I know it can be done but what are the consequencies"? My question is " have you heard of this being done and who makes these cond for centrifugal application"
No problems as such. An evaporative condenser is hybridized model of cooling tower and a condenser and technically there is no difference. You have to have a correct sizing.
Yes, surging could be a problem. Are you planning to construct a centrifugal chiller from scratch, or is the evaporative condenser a modification to an existing chiller?
Currently the centrifugal chiller is using a water cooled condenser. I am investigating the advantage of using an evap. condenser (cooling tower) to increase efficiency but was concerned about possible problems with lower head pressure.
Thanks for your help!
You will have to talk to mfg because of the possibility of pressure drop on the lift which is rather small compaired to Pos Disp comp, thats why I questioned weather it was being done.
Actually I never did it so far nor seen it for centrifugals. Imok2 raised a valid point about lift and I think this can be overcome by placing compressor at a heigher elevation(just out of theory).
Surge problems can be taken care by a liquid receiver.
