–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Maintenance du pare gouttelette (d\u00e9pose, nettoyage, pose)<\/p>\n
–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Maintenance du groupe de ventilation (d\u00e9pose de la courroie, pose d\u2019une nouvelle courroie, r\u00e9glage de l\u2019alignement et de la tension)<\/p>\n
Le banc CRA542 permet l\u2019\u00e9tude d\u2019une centrale de traitement d\u2019air industrielle de type double flux (deux ventilateurs). Elle comporte les \u00e9l\u00e9ments classiques d\u2019un r\u00e9seau de traitement, \u00e0 savoir\u00a0: des filtres, une batterie froide, un groupe d\u2019eau glac\u00e9e, un humidificateur, une batterie chaude, un ventilateur de soufflage, un ventilateur de reprise et des registres de m\u00e9lange.<\/p>\n
Les \u00e9tudiants devront dans un premier temps identifier les composants de la centrale et les sens de circulation de l\u2019air.<\/p>\n
Ils devront ensuite mettre en service le syst\u00e8me suivant les conditions fix\u00e9es par l\u2019enseignant (mode climatisation ou mode chauffage).<\/p>\n
Lorsque le r\u00e9gime de fonctionnement est \u00e9tabli, ils doivent alors mesurer les param\u00e8tres de fonctionnement (temp\u00e9rature, hygrom\u00e9trie, d\u00e9bit d\u2019air) avec les appareils portables fournis.<\/p>\n
Le travail suivant est d\u2019exploiter les mesures en tra\u00e7ant le cycle de l\u2019air sur un diagramme psychrom\u00e9trique et en calculant les puissances des \u00e9changeurs.<\/p>\n
Le banc de traitement d\u2019air permet \u00e9galement de faire des op\u00e9rations de maintenance\u00a0:<\/p>\n
-v\u00e9rification de la propret\u00e9 des filtres (par mesure de pression diff\u00e9rentielle) et op\u00e9ration de remplacement<\/p>\n
-v\u00e9rification du bon fonctionnement du ventilateur (mesure de la hauteur manom\u00e9trique g\u00e9n\u00e9r\u00e9e en fonction de la vitesse)<\/p>\n
-nettoyage du filtre pare gouttelettes (avec op\u00e9ration de d\u00e9montage et de remontage)<\/p>\n
-remplacement de la courroie de transmission du ventilateur avec op\u00e9ration de d\u00e9montage, remontage et r\u00e9glage de l\u2019alignement et de la tension<\/p>\n
La conception robuste de cet \u00e9quipement le rend parfaitement adapt\u00e9 pour une utilisation en milieu scolaire. Sa structure en aluminium anodis\u00e9e sur roues lui conf\u00e8re une tr\u00e8s grande robustesse ainsi qu\u2019une grande souplesse d\u2019int\u00e9gration dans vos locaux. La fabrication de cet \u00e9quipement r\u00e9pond \u00e0 la directive machine\u00a0 europ\u00e9enne.<\/p>\n","protected":false},"excerpt":{"rendered":"
