Abstract

L'invention concerne un compresseur à spirale et un climatiseur. Le compresseur à spirale (100) comprend un élément de volute orbital (30) et un élément de volute non orbital (20) qui viennent en prise l'un avec l'autre pour former une cavité de compression (1a). L'élément de volute non orbital (20) comprend un corps d'élément non orbital (21). Le corps d'élément non orbital (21) comporte un premier canal (213) s'étendant à travers le corps d'élément non orbital (21) dans la direction axiale, un deuxième canal (214) s'étendant sur une face latérale du corps d'élément non orbital dans la direction radiale, et un troisième canal dont une extrémité est en communication avec le premier canal (213) et dont l'autre extrémité est en communication avec le deuxième canal (214). Une plaque de vanne mobile (40) est disposée dans le troisième canal. La plaque de vanne mobile (40) commande le premier canal (213) et le deuxième canal (214) de façon à être en communication l'un avec l'autre ou déconnectés l'un de l'autre en fonction de la différence de pression d'air entre le premier canal (213) et le deuxième canal (214). Par conséquent, quand il n'est pas nécessaire d'acheminer des réfrigérants vers le compresseur, le volume d'espacement pour la communication du premier canal (213) et du deuxième canal (214) avec la cavité de compression est réduit, et les performances du compresseur à spirale sont améliorées.
