ABSTRACT:
A passive emergency ventilation system and method. The system includes a storage facility for a substantial volume of compressed or preferably liquified air in or near a room to be ventilated. During an emergency event, air from the storage facility is gasified in a liquid air gasifier and flows through one or more eductors. The eductors are used to draw additional ambient air into the system. The ambient air may optionally be cooled through one or both of mixing with the incoming stored air and/or using the incoming ambient air to heat liquid air gasifiers.
