This example demonstrates the modeling of a room with one person and CO2 control.
The room has a volume of 4*4*2.7 m3, and the CO2 inflow is from
one person.
A control system regulates the outside air to maintain a CO2 concentration of 1000 PPM
in the room. The outside air has a CO2 concentration of 300 PPM.
Note that for simplicity, we allow zero outside air flow rate if the CO2 concentration is below
the setpoint, which does not comply with ASHRAE regulations.

Added a flow resistance between the volume and the ambient to decouple the
state of the volume from the boundary conditions. This is needed to allow
a pedantic model check in Dymola 2014, as otherwise, the initial conditions of
the volume could not be specified without introducing redundant equations.
