Title
(EN) IMPROVED COMPRESSOR DEVICE
(FR) DISPOSITIF DE COMPRESSEUR AMELIORE
Abstract
(EN)
Improved compressor device which mainly consists of a case (2) containing a compressor element (6) that is powered by a variable speed motor (7) with a control box (8) with a set maximum number of revolutions (Nmax)for the compressor element (6), an air cooling (10) which suck air from the environment via an inlet (11) and blows it back to the environment through the case (2) and via an exhaust (12) and a cooling circuit (13) for the cooling of the gas which has been compressed by the compressor element (6), characterized in that the control box (8) is equipped with an algorithm (24) that reduces the abovementioned maximum allowed set number of revolutions (Nmax) to a defined level as soon as the monitored environmental temperature (T20) rises above a maximum set level (Tmax), and the maximum allowed set number of revolutions (Nmax) again rises as soon as the environmental temperature (T20) falls below the above mentioned level (Tmax).
(FR)
Dispositif de compresseur amélioré constitué principalement d'un carter (2) contenant un élément (6) de compresseur entraîné par un moteur (7) à vitesse variable à l'aide d'un boîtier (8) de commande spécifiant un nombre de tours maximal (Nmax) pour l'élément (6) de compresseur, un dispositif (10) de refroidissement par air aspirant de l'air à partir de l'environnement par une entrée (11) et le refoulant vers l'environnement à travers le carter (2) et via un échappement (12), et un circuit (13) de refroidissement destiné à refroidir le gaz comprimé par l'élément (6) de compresseur, caractérisé en ce que le boîtier (8) de commande est équipé d'un algorithme (24) réduisant le nombre de tours maximal admis (Nmax) spécifié susmentionné à un niveau défini dès que la température (T20) sous surveillance de l'environnement s'élève au-dessus d'un niveau maximal spécifié (Tmax), et en ce que le nombre de tours maximal admis (Nmax) spécifié augmente à nouveau dès que la température (T20) de l'environnement tombe au-dessous du niveau (Tmax) susmentionné.
