Information

Model that demonstrates the use of an ideal heater and an ideal cooler.

The heater model has an almost unlimited positive capacity (Q_flow_nominal = 1.0e10 Watts), and hence its outlet temperature always reaches the set point temperatures.

The cooler model has a limited negative capacitiy (Q_flow_nominal = 1000 Watts), and hence its outlet temperature reaches only a limited value corresponding to its maximum negative capacity.

There is also a heater and cooler with unlimited capacity.

At t=1000 second, the flow reverses its direction.

Each flow leg has the same mass flow rate. There are three mass flow sources as using one source only would yield a nonlinear system of equations that needs to be solved to determine the mass flow rate distribution.

The heater and cooler models have the parameter show_T set to true to allow inspecting the temperatures at their ports.
