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

TypeNameDefaultDescription
Realr_V[:]r_V(each min=0, each final u...Normalized air volume flow rate at user-selected operating points [1]
Realf[size(r_V, 1)]f(each min=0, each final uni...Normalized performance factor at these flow rates [1]

Modelica definition

record AirFlow "Record for primary air parameters" extends Modelica.Icons.Record; parameter Real r_V[:](each min=0, each final unit="1") "Normalized air volume flow rate at user-selected operating points"; parameter Real f[size(r_V, 1)](each min=0, each final unit="1") "Normalized performance factor at these flow rates"; end AirFlow;

Buildings.Fluid.HeatExchangers.ActiveBeams.Data.BaseClasses.TemperatureDifference 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).
