This model represents the heat pump isolation valves.
The isolation valves are modeled as two-way two-position
valves, which can be located at the heat pump inlet and/or
outlet depending on the settings of the parameters have_valHpInlIso
and have_valHpOutIso
.
It is assumed that the heat pumps always provide heating hot water.
Optionally, chilled water return and supply and the associated isolation valves
can be modeled by setting the parameter have_chiWat
to true.
By default, the isolation valves are modeled considering a linear
variation of the pressure drop with the flow rate (linearized=true
),
as opposed to the quadratic relationship usually considered for
a turbulent flow regime.
By limiting the size of the system of nonlinear equations, this setting
reduces the risk of solver failure and the time to solution.
