# .Annex60.Fluid.Sensors.Conversions.Examples.To_VolumeFraction

Example problem for conversion model

## Information

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.

## Revisions

- March 27, 2013 by Michael Wetter:
  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.
- February 13, 2010 by Michael Wetter:
  First implementation.
