Package Modelica.Thermal.HeatTransfer.FahrenheitComponents with Fahrenheit input and/or output
Package Modelica.Thermal.HeatTransfer.Fahrenheit
The components of this package are provided for the convenience of people working mostly with Fahrenheit units, since all models in package HeatTransfer are based on Kelvin units.
Note, that in package SIunits.Conversions, functions are provided to convert between the units Kelvin, degree Celsius, degree Fahrenheit and degree Rankine. These functions allow, e.g., a direct conversion of units at all places where Kelvin is required as parameter. Example:
import SIunits.Conversions.*;
Modelica.Thermal.HeatTransfer.HeatCapacitor C(T0 = from_degF(70));

Model Modelica.Thermal.HeatTransfer.Fahrenheit.FixedTemperature
This model defines a fixed temperature T at its port in [degF], i.e., it defines a fixed temperature as a boundary condition.
| Type | Name | Default | Description |
|---|---|---|---|
Temperature_degF | T | Fixed Temperature at the port |

Model Modelica.Thermal.HeatTransfer.Fahrenheit.PrescribedTemperature
This model represents a variable temperature boundary condition The temperature value in [degF] is given by the input signal to the model. The effect is that an instance of this model acts as an infinite reservoir able to absorb or generate as much energy as required to keep the temperature at the specified value.

input RealInput | T |
Model Modelica.Thermal.HeatTransfer.Fahrenheit.TemperatureSensor
This is an ideal absolute temperature sensor which returns the temperature of the connected port in Fahrenheit as an output signal. The sensor itself has no thermal interaction with whatever it is connected to. Furthermore, no thermocouple-like lags are associated with this sensor model.
