modelChillerBorefield
Example of the ETS model with heat recovery chiller and borefield
Extends from ChillerOnly (Example of the ETS model with heat recovery chiller).
Information
This model validates Buildings.Obsolete.DHC.ETS.Combined.ChillerBorefield in a system configuration including a geothermal borefield. See Buildings.Obsolete.DHC.ETS.Combined.Examples.ChillerOnly for the description of the main modeling assumptions.
