Buildings.Fluid.Storage.BaseClasses.Examples.IndirectTankHeatExchanger

Information

This model provides an example of how the Buildings.Fluid.Storage.BaseClasses.IndirectTankHeatExchanger model is used. In the model water flows from a flow source through the heat exchanger to a low pressure environment. The stagnant fluid on the outside of the heat exchanger is modeled as a constant temperature.
