recordTemperatureDifference
Record for temperature difference
Extends from Modelica.Icons.Record (Icon for records).
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.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real[:] | r_dT | Normalized temperature difference, e.g., temperature difference at user-selected operating points divided by nominal temperature difference. Must be positive. | |
| Real[size(r_dT, 1)] | f | Normalized performance factor at these normalized temperature differences |
