Abstract

Est divulgué un climatiseur comprenant un dispositif de réglage de débit. Un climatiseur comprend : un boîtier comportant des premier et second orifices d'évacuation ; un ventilateur de ventilation disposé dans le boîtier ; un échangeur de chaleur échangeant de la chaleur avec l'air évacué du ventilateur de ventilation ; un premier trajet d'écoulement qui guide l'air qui a traversé l'échangeur de chaleur vers le premier orifice d'évacuation ; un second trajet d'écoulement qui est relié au premier trajet d'écoulement et guide l'air qui a traversé l'échangeur de chaleur vers le second orifice d'évacuation ; et un dispositif de réglage de débit qui est prévu pour régler le débit de l'air guidé vers le premier orifice d'évacuation et le second orifice d'évacuation, le dispositif de réglage de débit comprenant : un amortisseur qui est disposé sur le premier trajet d'écoulement et peut bloquer l'écoulement d'une partie de l'air dans le premier trajet d'écoulement vers le premier orifice d'évacuation de telle sorte que le débit guidé vers le premier orifice d'évacuation puisse être réduit ; et une soupape qui est disposée entre le premier trajet d'écoulement et le second trajet d'écoulement et permet au premier trajet d'écoulement et au second trajet d'écoulement d'être en communication de manière sélective l'un avec l'autre de telle sorte qu'une partie de l'air dans le premier trajet d'écoulement soit déplacée vers le second trajet d'écoulement et que le débit dans le second trajet d'écoulement puisse être augmenté.
