Record 1 2013-09-13

English

Subject field(s)
  • Cooling and Ventilating Systems
CONT

Power roof ventilators are usually roof mounted and utilize either centrifugal or axial blade fans. Both types are generally used in low-pressure exhaust systems for factories, warehouses, etc.

French

Domaine(s)
  • Systèmes de refroidissement et de ventilation
CONT

Ventilateurs-extracteurs de toiture. Ils sont souvent utilisés pour assurer le renouvellement d'air des usines, entre autres celles où il y a d'importants dégagements de chaleur (fonderies, aciéries, etc.), mais aussi pour la ventilation des toilettes et cuisines. Ils sont presque toujours installés en toiture. L'introduction d'air a lieu en été par les portes et les fenêtres, ou mieux encore, surtout en hiver, est assurée par une installation d'insufflation mécanique.

CONT

Extracteurs de toiture. Il existe une troisième famille de ventilateurs spécialement destinée à l'extraction d'air vicié des locaux et qui sont conçus pour être installés en toiture des bâtiments.

Key term(s)
  • ventilateur d'extraction

Subject field(s)
  • Roofs (Building Elements)
DEF

A device installed on the roof for the purpose of ventilating the interior of the building.

OBS

Frequently combined with motorized fan equipment mounted on the roof, to provide positive air flow.

French

Domaine(s)
  • Toitures (Éléments du bâtiment)
DEF

Dispositif placé sur le toit pour aérer l'intérieur du bâtiment.

OBS

Souvent combiné à un ventilateur à moteur servant à faire circuler l'air.

Record 3 2007-05-24

English

Subject field(s)
  • Drying Techniques (Farming)
CONT

The batch-in-bin drying process involves using a bin as a batch dryer. A 3 to 4-foot deep layer of grain is placed in the bin and the fan and heater started. Typical drying air temperatures are 120 to 160F with airflow rates of 8 to 15 cfm/bushel. Drying begins at the floor and progresses upward. Grain at the floor of the bin becomes excessively dry while the top layer of the batch remains fairly wet. The grain is cooled in the bin after it is dried. Some batch-in-bin dryers hold the grain being dried in a layer near the roof. After the grain is dried it is dropped to the bin floor where it is cooled. As the grain is moved from the bin, the grain is mixed, and the average moisture content going into final storage should be low enough that mold growth will not be a problem.

Key term(s)
  • batch drier

Domaine(s)
  • Dessiccation (Techniques agricoles)
DEF

Appareil dans lequel la masse du produit à traiter est introduite par lots maintenus en place pendant toute la durée de l'opération. Après vidange, de nouveaux lots sont mis en place et le cycle recommence.

Record 4 2005-04-26

English

Subject field(s)
  • Building Ventilation
  • Roofs (Building Elements)
CONT

Whirly Vent Ventilation. The Whirly Vent ventilation system is effective all year round, removing hot and moisture-laden air from roof cavities and rooms and replacing summer heat and winter damp with fresh air. [Text accompanied by an illustration.]

CONT

Whirly Bird Vents. These vents have a rotating top section that assist the flow of warm air to disperse. [Text accompanied by an illustration].

CONT

Makes a dramatic difference to roof space temperatures. The in roof Fan changes air in the roof space between 50 and 70 times per hour, too fast for heat to build up much beyond the outside temperature. You would need 30 or more whirly type wind turbines and a strong breeze to achieve this rate of airflow.... Existing "whirly birds" can be incorporated as part of the exhaust system but have to be supplemented with additional vents as their free air area is far too small.

French

Domaine(s)
  • Ventilation (Construction)
  • Toitures (Éléments du bâtiment)
CONT

La compagnie [Ventilation Maximum] offre [...] des ventilateurs statiques pour remplacer les vieilles turbines de ventilation. Ces turbines sont souvent bruyantes ou bloquées, elles peuvent aussi causer des infiltrations de neige. Le ventilateur statique évitera ces problèmes et peut être installé directement sur l'ancienne ouverture prévue pour la turbine. L'étanchéité du toit ne sera donc pas touchée par ce remplacement.

PHR

Turbine de ventilation de toit.

English

Subject field(s)
  • Cooling and Ventilating Systems
CONT

In addition to the axial and centrifugal fan classifications, a third class for special designs exists. This classification covers tubular centrifugal fans and axial-centrifugal, power roof ventilators. The tubular centrifugal type is often used a return-air fan in low-pressure HVAC systems. Air is discharged from the impeller in the same way as in standard centrifugal fans and then changed 90 ° in direction through straightening vanes.
