This model validates the model Buildings.Fluid.HeatExchangers.CoolingTowers.Merkel by comparing against results obtained from EnergyPlus.
The EnergyPlus results were obtained using the example file
CoolingTower:VariableSpeed, with the cooling tower evaluated as
the CoolingTower:VariableSpeed:Merkel model from EnergyPlus.
The difference in results of the cooling tower's leaving water temperature
(tow.TLvg and TLvg.EP)
during the middle and end of the simulation is because the mass flow rate is
zero. For zero mass flow rate, EnergyPlus assumes a steady state condition,
whereas the Modelica model is a dynamic model and hence the properties at the
outlet are equal to the state variables of the model.
