.Buildings.Templates.Components.Chillers.Compression .Buildings.Templates.Components.Chillers.CompressionThis is a model for air-cooled or water-cooled compression
chillers where the capacity and input power are computed by
interpolating manufacturer data along the evaporator entering or
leaving temperature, the condenser entering or leaving temperature
and the part load ratio. The model can be configured to represent
either a cooling-only chiller (have_switchover=false)
or a heat-recovery chiller (have_switchover=true) that
can be controlled to track either a CHW temperature setpoint or a
HW temperature setpoint.
This model is a wrapper for Buildings.Fluid.Chillers.ModularReversible.TableData2DLoadDep, which the user may refer to for the modeling assumptions. Note that, by default, internal safeties in this model are disabled.
The following input and output points are available.
