Ammonia Circulation rate - by Frick/ Vitler
We are working on a project where in the capacity of total plant is 100TR at -40 Deg C. We are having Four compressors & Two Independent systems. i.e. TWo Hp / TWO Lp Vessles. to have an 100% stand by plus to offset the non peak conditions.
The flow rate for the pumps ( Again total 4 pumps- 2 S.B.) is coming out to @ 5.3 Cmt/ Hr. I remember that Frick has given some specific figure for 4:1 Circulation rate. I do not have that chart now. Bit I believe that our calculations are almost 40% above the figures given by Frick? What could be the reason. has any one those Frick/ Vitler charts?
