Excess ventilation |
|
evaluated |
|
|
|
Due to internal or external heat sources (passengers, lights, electrical equipment, sunshine through the windows) temperature inside coaches may rise beyond 20° C even for much lower outside temperatures. In this case the coach may be cooled by outside air through an excessive operation of ventilation. This saves energy for air-conditioning.
