多管路熱交換器の自動制御(第1報) : 2管路熱交換器の動特性

抄録

Two tube-pass, one shell-pass type heat exchangers are analysed exactly. The heat exchangers of this type contain both parallel and counter flow heat exchange processes. System parameters are combined and arranged in dimensionless forms, and for the typical combinations of these system parameters the transfer functions are obtained. An examp1e of frequency response is given and compared with simp1e parallel and counter flow heat exchanger in equal flow conditions. These dynamic characteristics show that the heat exchangers of this type may be conditionally stable and that its control is delicate.
