CO2-based demand control for coach ventilation |
|
evaluated |
|
|
|
The ventilation of confined spaces can be controlled according to demand by using CO2-concentration as an indicator for occupancy. This concept can be applied to railway passenger coaches and saves energy since less outside air has to be heated or cooled to inside temperature.
