modelRefrigerantCycleHeatRecovery
Refrigerant cycle model for cooling-only or heat recovery chiller models
Extends from Buildings.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialModularRefrigerantCycle (Partial refrigerant cycle model).
Information
This is the refrigerant cycle model used in Buildings.Fluid.Chillers.ModularReversible.TableData2DLoadDep.
In contrast to
Buildings.Fluid.Chillers.ModularReversible.BaseClasses.RefrigerantCycle,
this model includes a unique component that can be configured to
either represent a cooling-only chiller (have_switchover=false)
or a heat recovery chiller (have_switchover=true).
A unique performance data file is required, providing
the maximum cooling heat flow rate and power, regardless of the setting
for have_switchover.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_rev (from PartialModularRefrigerantCycle) | true | True if the refrigerant machine is reversible |
| Boolean | have_switchover | false | Set to true for heat recovery chiller with built-in switchover |
