Title (EN) HIGH-EFFICIENCY AIR-CONDITIONING SYSTEM WITH HIGH-VOLUME AIR DISTRIBUTION
(FR) SYSTEME DE CONDITIONNEMENT D'AIR A HAUTE EFFICACITE AVEC DISTRIBUTION D'UN GRAND VOLUME D'AIR
Abstract:
(EN) A system and method for providing conditioned air to the interior space of a building (6) includes separate dehumidification and sensible cooling functions. The separate dehumidification (9) allows for much higher supply air temperatures, preferably within about 10 °F to about 15 °F of the air temperature of the building space. Low-velocity air distribution through a ceiling plenum (4) or a vent (5) into the space allows for very low fan static pressures, which greatly reduces fan energy usage compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling (4) construction with little modification. Optional return air channels between an inner glazing and an outer glazing of exterior windows (19) can virtually eliminate heating loads at the building perimeter (44), which virtually eliminates the need for simultaneous heating and cooling. The result is a major improvement in energy efficiency and comfort while reducing installed cost of the system.
(FR) Système et procédé permettant de fournir de l'air conditionné à l'espace interne d'un bâtiment, qui comporte des fonctions séparées de déshumidification et de refroidissement sensible. La déshumidification séparée permet des températures beaucoup plus élevées d'air alimenté, de préférence dans la plage d'environ 10 °F à environ 15 °F de la température de l'air de l'espace intérieur du bâtiment. La répartition de l'air à faible vitesse par une chambre de diffusion d'air ou un évent dans l'espace du bâtiment permet des pressions statiques de ventilateur très faibles, qui réduisent fortement l'utilisation de l'énergie de ventilateur par rapport aux systèmes canalisés classiques. Les faibles pressions statiques et les températures élevées de l'air alimenté permettent l'utilisation de la construction existante des plafonds suspendus avec des modifications minimes. Des canaux éventuels de retour d'air entre une vitre interne et une vitre externe de fenêtres extérieures peuvent effectivement éliminer les charges de chauffage sur le périmètre du bâtiment, ce qui élimine le besoin simultané de chauffage et de refroidissement. Il en résulte une amélioration considérable de l'efficacité énergétique et du confort, parallèlement à une réduction du coût installé du système.
