Abstract

L'invention porte sur un dispositif de récupération de chaleur totale réduisant efficacement une consommation d'énergie dans un traitement d'air frais, lequel dispositif comprend : un échangeur de chaleur air/air (1), une entrée d'air frais (11), une sortie d'air frais (12), une entrée d'air d'échappement (13), une sortie d'air d'échappement (14) et un système de pulvérisation d'eau qui pulvérise de l'eau sous la forme d'un brouillard de gouttelettes d'échelle micrométrique. Le système de pulvérisation d'eau comprend un réservoir d'eau pulvérisée (2), un pulvérisateur (21), une pompe à eau (24), un capteur d'humidité (23) disposé dans la sortie d'air d'échappement (14), et un dispositif de commande de pulvérisation (22). Le dispositif de commande de pulvérisation (22) commande la quantité d'eau pulvérisée du pulvérisateur (21) de façon à maintenir une humidité relative à la sortie d'air d'échappement (14) proche de 100 % ou égale à 100 %. Le dispositif de récupération de chaleur totale transfère efficacement la chaleur de l'air frais à un air d'échappement, et émet l'air d'échappement vers l'extérieur, ce qui réduit considérablement la température et l'humidité de l'air frais, de façon à réduire la charge de refroidissement d'un système de ventilation. Dans ce processus, seulement de la chaleur, mais non une masse d'air frais et d'air d'échappement, est transférée, empêchant de l'air frais d'être pollué dans le processus de récupération de chaleur.
