modelHeatRecoveryChiller
Validation model for heat recovery chiller
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.HeatRecoveryChiller.
The CHW and HW return temperatures and flow rates are at their design values. The HRC supply temperature setpoint is switched from the design CHW supply temperature to the design HW supply temperature when the HRC operating mode is switched from cooling to heating.
