Information

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

The heater model has a capacity of Q_flow_max = 1.0e4 Watts and the cooler model has a capacitiy of Q_flow_min = -1000 Watts. Hence, both only track their set point of the outlet temperature during certain times. 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.
