Personal air supply devices integrated with chairs are adapted for use in
conjunction with building or vehicle ventilation systems. The personal air supply
devices include ducts, a tube and a nozzle arranged to direct a portion of the
air from the building or vehicle ventilation system at the facial zone of a person
sitting in the chair. The personal air supply devices include airflow regulating
devices for regulating the flow of air through the nozzle. The tubes and nozzle
are configured to release air from the ventilation system very close to the nose
and mouth of a person in the chair to prevent mixing with ambient air and maximize
the cooling and refreshing effect of the conditioned air. The building or vehicle
ventilation system may be operated at lower ventilation rates without causing discomfort
to persons provided with personal air supply devices.
