.Buildings.Fluid.HeatExchangers.CoolingTowers.DryCooler .Buildings.Fluid.HeatExchangers.CoolingTowers.DryCoolerModel for a steady-state or dynamic dry cooling tower with a variable speed fan using epsilon-NTU method for heat transfer.
To compute the thermal performance, this model takes as parameters the nominal cooling capacity, air dry-bulb temperature, and cooling fluid (water or glycol) inlet and outlet temperatures as specified in the data record Buildings.Fluid.HeatExchangers.CoolingTowers.Data.DryCooler.Generic. The cooling tower performance is modeled using the effectiveness-NTU relationship for a crossflow configuration.
Changes in convective heat transfer coefficient on the coolant-side and the air-side due to change in flow rate and temperature are taken into account using the model Buildings.Fluid.HeatExchangers.BaseClasses.HADryCoil. This correction can be configured in the data record Buildings.Fluid.HeatExchangers.CoolingTowers.Data.DryCooler.Generic.
