Information

This model validates the load calculation logic of the block Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.TableData2DLoadDep for different system configurations and operating modes.

  • The component chiSupLvg validates the block for chiller applications with CHW supply temperature control and performance data interpolation based on evaporator and condenser leaving temperature.
  • The component chiRetEnt validates the block for chiller applications with CHW return temperature control and performance data interpolation based on evaporator leaving and condenser entering temperature.
  • The component chiHeaSupLvg validates the block for heat recovery chiller applications with HW supply temperature control and performance data interpolation based on evaporator and condenser leaving temperature.
  • The component hpSupLvg validates the block for heat pump applications with HW supply temperature control and performance data interpolation based on evaporator and condenser leaving temperature.

The validation is carried out by computing the tracked temperature using the heat flow rate calculated by the block, and feeding back this variable along with the required part load ratio as inputs. It is then expected that the tracked temperature matches the setpoint. Further validation of the performance calculation algorithm by comparison to polynomial chiller models is available in the package Buildings.Fluid.Chillers.ModularReversible.Validation.
