Abstract

L'invention porte sur un dispositif de climatisation qui peut empêcher la condensation produite par un échangeur de chaleur d'adhérer à un ventilateur. Un dispositif de climatisation comprend un circuit de cycle de réfrigération comprenant un compresseur, un échangeur de chaleur côté source de chaleur, un dispositif d'étranglement et un échangeur de chaleur à air cible qui sont raccordés par des tuyaux. Le dispositif de climatisation comporte une unité de ventilateur qui contient un ventilateur, et une unité d'échangeur de chaleur à air cible qui renferme l'échangeur de chaleur à air cible. L'unité de ventilateur est disposée plus en amont que l'unité d'échangeur de chaleur à air cible dans la direction dans laquelle s'écoule l'air produit par le ventilateur.
