Heat Exchanger Technology

Monday, August 20, 2007


Basic heat transfer relationships is apply to Air-Cooled Heat Exchanger (ACHE). The fundamental heat ransfer equation :

Q = U. A. LMTD.F

where
U = overall heat transfer coefficient
A = Heat transfer area
LMTD = Log mean temperature difference
F = Correction factor

Typical heat transfer coefficient for Air-Cooled Heat Exchangers
