  • a proportion of a mixed gas in the present case, a proportion of fresh air, is mixed. Consequently, as a rule, the conditioning device 106 is always flowed through by a mixture of the exhaust air 104 and fresh air 56.
  • a process air line 130 with a valve 132 leads to the air inlet 16 of the treatment device 96, so that the flow circuit is closed.

Abstract

L'invention concerne un dispositif de conditionnement d'air ambiant et/ou de processus comprenant un système de buses (8), qui comporte une pluralité de buses (14) disposées dans au moins un conduit de buses (28) et destinées à pulvériser un liquide, et au moins une pompe au moyen de laquelle le liquide à pulvériser est mis sous pression. Les buses (14) sont conçues comme des buses de turbulence et/ou la pompe (34) soumet le liquide à pulvériser à une pression comprise entre 3 et 50 bar. Selon l'invention, le liquide, en particulier de l'eau, peut être nébulisé de manière particulièrement fine et un bon degré d'évaporation peut être obtenu, ce qui réduit également la quantité d'eau perdue. Le dispositif de l'invention se caractérise par une faible sensibilité aux interférences, une longue durée de vie de la pompe (34) et un faible entretien.
