Abstract

Le présent dispositif (1) de climatisation pour véhicules comporte: un unité (10) de chauffage de siège installée dans un intérieur de véhicule à un position dans un siège (30) sur lequel est assis un occupant du véhicule, et chauffant une zone (WS) à chauffer située au-dessus de la surface (31) d'assise du siège; et un unité (50) de refroidissement installée dans la partie supérieure de l'intérieur de véhicule et fournissant de l'air frais (CA) à une zone (CS) à refroidir située au-dessus de la zone à chauffer. Dans l'unité de chauffage de siège, un cycle frigorifique (11) du type à compression de vapeur et une soufflante (16) peuvent être contenus dans un boîtier (20). L'unité de chauffage de siège peut chauffer le tronc et les jambes de l'occupant du véhicule assis sur le siège. Dans l'unité de refroidissement, un cycle frigorifique (51) du type à compression de vapeur et une soufflante (56) peuvent être contenus dans un boîtier (60). L'unité de refroidissement peut refroidir la tête de l'occupant du véhicule assis sur le siège. Du fait de cette configuration, la différence entre les températures de la tête et des jambes de l'occupant du véhicule est assurée dans un état tête froide/pieds chauds, rendant ainsi possible une amélioration du confort de l'occupant du véhicule.
