Le climatiseur de l'invention transfère le fluide de travail en utilisant la force d'entraînement générée dans le dispositif à dépression et la pompe disposés dans le circuit de circulation du fluide de travail, la force capillaire d'un fluide de travail liquide généré dans un canal de transfert de l'unité d'évaporation, la différence de pression, la pompe, etc., ce qui améliore le rendement du climatiseur pour véhicule.
