hi everyone,
I have a nh3 refrigeration project which need to use a thermosiphon evaporator. I made a calculation but I'm not sure with the result.so I need someone can make a check on my calculation.
Qe=2300KW,Te=-38℃,cacl2 brine 29% by wt, -30/-35℃,
the calculation:
area=656m2, ¢20*2, l=8000, number=1310,tube pitch=26, shell id=1010mm, recirculation rate=4,
fouling resistence:shell/tube 0.00017/0.000088 m2.k/W
it's the first time to do this so i need your help.
many thanks!
