Model Modelica.Thermal.HeatTransfer.Sources.FixedTemperature
This model defines a fixed temperature T at its port in Kelvin, i.e., it defines a fixed temperature as a boundary condition.

Model Modelica.Thermal.HeatTransfer.Sources.PrescribedTemperature
This model represents a variable temperature boundary condition. The temperature in [K] is given as input signal T 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.

Model Modelica.Thermal.HeatTransfer.Sources.FixedHeatFlow
This model allows a specified amount of heat flow rate to be "injected" into a thermal system at a given port. The constant amount of heat flow rate Q_flow is given as a parameter. The heat flows into the component to which the component FixedHeatFlow is connected, if parameter Q_flow is positive.
If parameter alpha is <> 0, the heat flow is multiplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given with respect to reference temperature T_ref).

Model Modelica.Thermal.HeatTransfer.Sources.PrescribedHeatFlow
This model allows a specified amount of heat flow rate to be "injected" into a thermal system at a given port. The amount of heat is given by the input signal Q_flow into the model. The heat flows into the component to which the component PrescribedHeatFlow is connected, if the input signal is positive.
If parameter alpha is <> 0, the heat flow is multiplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given with respect to reference temperature T_ref).
