13 Heat exchange cell m H h HI m H h HO m C h CI m C h CO Cell model: detailed picture Cell model: icon representation Q CELL Definition Two perfectly stirred tanks, exchanging heat only with each other through a dividing wall H=Hot, C=Cold; HI=Hot Inlet, HO=Hot Outlet CI=Cold Inlet, CO=Cold Outlet Assumptions Perfect mixing in the fluid cells Constant fluid densities The tanks are completely full Constant specific heat capacities The thermal resistance of the wall is neglected The wall heat capacity is taken into account

Slide 18

18 Summary on the cell model Distributed models become inefficient for complex heat exchangers From the lumped mostly cell models are employed The cell parameters need to be carefully estimated accounting for the underestimation of the temperature differences A method for direct identification of the number of cells has been developed Mostly applicable to shell-and-tube heat exchangers A useful visualisation of the cell number identification procedure is provided The method can be further extended to the other kinds of heat exchangers
