EndUses

The EndUses package clusters all appliances within an household that allow interaction with a water consumer. They are of special interest because they are associated with a consumer-generated flow of water that acts as a trigger for the rest of the system’s building blocks.

BaseEndUses

Model Name	BasicValve	Partial Model for the definition of end-uses
Type	Partial Model
Inlets	inletCold	cold water inlet
	inletHot	hot water inlet
	flowInput	data input from e.g. block HydrographFromFile
Outlets	outlet	water outlet

Partial model acting as a basic valve: two water inlets mixing into one water outlet. The flow is triggered by the flowInput port.

Showers

Base Shower

Model Name	BaseShower	Partial Model for showers
Type	Partial Model
Parameters	T_wanted	Targeted Temperature

Base model for showers. It simply makes sure \(T_{cold} \leq T_{wanted} \leq T_{hot}\) using a trivial algorithm:

algorithm
  if T_wanted < inletCold.T then
    T_achieved := inletCold.T;
  elseif T_wanted > inletHot.T then
    T_achieved := inletHot.T;
  else
    T_achieved := T_wanted;
  end if;

Classic Shower

Model Name	ClassicShower	Lossless shower model
Type	Model	extends partial model BaseShower and partial model BasicValve
Inlets	inletCold	cold water inlet
	inletHot	hot water inlet
	flowInput	data input from e.g. block HydrographFromFile
Outlets	outlet	water outlet
Parameters	T_wanted	Targeted Temperature

Simple model for showers. The flow is triggered through the flowInput port, connected to e.g. an HydrographFromFile block. Energy and mass balance equations describe the thermal behavior:

\[T_{out} m_{out} = T_{in}^{cold} m_{in}^{cold} + T_{in}^{hot} m_{in}^{hot}\]

\[m_{in}^{cold} + m_{in}^{hot} = m_{out}\]

Taps

Model Name	ClassicShower	Lossless tap model
Type	Model	extends partial model BasicValve
Inlets	inletCold	cold water inlet
	inletHot	hot water inlet
	flowInput	data input from e.g. block HydrographFromFile
Outlets	outlet	water outlet
Parameters	T_wanted	Targeted Temperature

Analogous to Classic Shower.
