    (f) comparaison, au moyen des troisièmes moyens (29), du nombre n avec un nombre limite prédéfini nlim mémorisé dans la commande (10) ; et
    (g)évaluation de la différence Δn = (n - nlim) en ce qui concerne la présence d'un état de fonctionnement non admissible.
  14. Procédé selon la revendication 13, caractérisé en ce que les deuxièmes moyens (27) mettent de nouveau le compresseur (14) en marche seulement après l'écoulement d'une période de temps de retard ΔtV, respectivement après un arrêt.
  15. Procédé selon la revendication 14, caractérisé en ce que les deuxièmes moyens (27), respectivement après l'écoulement d'une période de temps de retard ΔtV après un arrêt du compresseur (14), déterminent d'abord si TK est supérieure ou égale à TK lim1, en ce qu'ils mettent le compresseur (14) de nouveau en marche lorsque TK est supérieure ou égale à TK lim1, et en ce que le dispositif de comptage est incrémenté de 1 et en ce que la nouvelle mise en marche du compresseur n'a pas lieu pour une période de temps de retard supplémentaire ΔtV lorsque TK est supérieure ou égale à TK lim1.
  16. Procédé selon l'une quelconque des revendications 13 à 15, caractérisé en ce que, pour le cas où Δn est supérieure ou égale à n1, n1 étant une valeur mémorisée dans la commande (10), un premier état de fonctionnement non admissible est indiqué.
