Buildings.Fluid.HeatExchangers.CoolingTowers.Examples.FixedApproachDryBulb
Test model for cooling tower with fixed approach temperature using the dry-bulb temperature
Information
This example illustrates the use of the cooling tower model
Buildings.Fluid.HeatExchangers.CoolingTowers.FixedApproach, using
the outdoor dry-bulb temperature as the potential for heat transfer.
Heat is injected into the volume vol
. An on/off controller
switches the cooling loop water pump on or off based on the temperature of
this volume.
The cooling tower outlet temperature has a fixed approach temperature to the
outdoor dry-bulb temperature.
