Au moyen de la combinaison des avantages d'une tour de refroidissement, d'une tour de refroidissement en circuit fermé et d'une tour de refroidissement d'air, et de la pleine utilisation des caractéristiques d'échange de chaleur entre l'eau et l'air, lorsque l'eau coule à travers la tour de refroidissement, elle augmente l'humidité de l'air et la capacité endothermique, améliore la capacité d'absorption de chaleur et diminue la température au thermomètre sec de l'air, et la tour de refroidissement refroidit le radiateur refroidi par air. Le radiateur refroidi par air peut régler automatiquement son état de fonctionnement conformément aux conditions climatiques environnementales et aux températures d'entrée et de sortie d'un fluide à refroidir. Lors du changement de la température ambiante extérieure et de l'humidité ou des températures d'entrée et de sortie du fluide à refroidir, un système de commande automatique régule la quantité d'écoulement d'eau et la quantité d'air apportée d'une buse d'atomisation et d'une pomme d'arrosoir, respectivement, et règle automatiquement le mode de fonctionnement du radiateur refroidi par air, ce qui permet de maintenir le radiateur refroidi par air toujours dans un mode de fonctionnement économique.
