.BuildingSystems.Fluid.HeatExchangers.BaseClasses.lmtd

Information

This function computes the log mean temperature difference of a heat exchanger.

Note that the implementation requires the temperature differences Ta1 - Tb2 and Tb1 - Ta2 to be not equal to each other.

Interface

function lmtd
  input Modelica.Units.SI.Temperature T_a1 "Temperature at port a1";
  input Modelica.Units.SI.Temperature T_b1 "Temperature at port b1";
  input Modelica.Units.SI.Temperature T_a2 "Temperature at port a2";
  input Modelica.Units.SI.Temperature T_b2 "Temperature at port b2";
  output Modelica.Units.SI.TemperatureDifference lmtd "Log-mean temperature difference";
end lmtd;
