Buildings.Fluid.HeatExchangers.ActiveBeams.Data.BaseClasses
Base classes for performance data
Information
This package contains performance curves for the active beam models.
Package Content
Name | Description |
---|---|
AirFlow | Record for primary air parameters |
TemperatureDifference | Record for temperature difference |
WaterFlow | Record for water parameters |
Buildings.Fluid.HeatExchangers.ActiveBeams.Data.BaseClasses.AirFlow
Record for primary air parameters
Information
Data record for performance data that describe the air volume flow rate versus the change in the rate of heating or cooling.
The normamlized volume flow rate rV must be strictly increasing, i.e., rVi < rVi+1. Both vectors, rV and f must have the same size.
Extends from Modelica.Icons.Record (Icon for records).
Parameters
Type | Name | Default | Description |
---|---|---|---|
Real | r_V[:] | r_V( e... | Normalized air volume flow rate at user-selected operating points [1] |
Real | f[size(r_V, 1)] | f( ... | Normalized performance factor at these flow rates [1] |
Modelica definition
Buildings.Fluid.HeatExchangers.ActiveBeams.Data.BaseClasses.TemperatureDifference
Record for temperature difference
Information
Data record for performance data that describe the normalized temperature difference versus the change in the rate of heating or cooling. The normalized temperature difference is defined as
rΔTi= ΔTi ⁄ ΔTnominal = (Twi-Tz) ⁄ (Tw,nominal-Tz),
where Twi is the water inlet temperature, Tz is the zone air temperature and Tw,nominal is the nominal water inlet temperature.
The normalized temperature difference rΔT must be strictly increasing, i.e., rΔTi < rΔTi+1. Both vectors, rΔT and f must have the same size.
Extends from Modelica.Icons.Record (Icon for records).
Parameters
Type | Name | Default | Description |
---|---|---|---|
Real | r_dT[:] | r_dT( ... | Normalized temperature difference, e.g., temperature difference at user-selected operating points divided by nominal temperature difference. Must be positive. [1] |
Real | f[size(r_dT, 1)] | f( ... | Normalized performance factor at these normalized temperature differences [1] |
