  • the second operating state B2 is also operated until in the
  • Method step V2 is determined that the state variable X is equal to or greater than a threshold value UB2B1.
  • This threshold value UB2B1 is determined by comparing the state quantity difference ⁇ 1 (MZ) and the state variable difference ⁇ 2 (MZ).

  • a procedure for adjusting the total compressor power provides, for example, that after passing through a first operating state Bl and a following second operating state B2, the state variable differences ⁇ 1 (MZ) and ⁇ 2 (MZ) are compared with each other after the minimum time periods MZ.
  • Compressor unit 12 and the shut-off valves 46i to 46 4 are possible.
  • Operating state Bl, B2 is smaller than that of the other operating state B2, Bl.
  • Conditional difference ⁇ 2 (MZ) in the second operating state B2 a stepwise reduction of the total compressor power for the first operating state Bl is performed, as long as the state variable difference
  • ⁇ ( ⁇ ) in the first operating state Bl is smaller than the state variable difference ⁇ 2 (MZ) in the second operating state B2.
  • an increase in the total compressor power likewise takes place stepwise until the state variable difference ⁇ 2 (MZ) in the second operating state B2 is again smaller than the state variable difference ⁇ 1 (MZ) in the first operating state B1.
  • Operating state Bl can not be reduced, otherwise the state variable X would no longer decrease in the first operating state Bl and the total compressor power in the second operating state B2 can not be increased, otherwise the state variable X would no longer increase in the second operating state B2.

Abstract

L'invention concerne un procédé pour faire fonctionner un équipement de réfrigération, comprenant un circuit dans lequel circule du réfrigérant, avec lequel au moins une grandeur d'état est utilisée dans un système en vue de commander une puissance totale du compresseur de l'équipement de réfrigération, le procédé visant à faire fonctionner l'équipement de réfrigération avec des fluctuations les plus faibles possible. Selon l'invention, en fonction de ladite grandeur d'état, le groupe compresseur fonctionne soit dans un premier état opérationnel avec une première puissance de compresseur totale, dans lequel la grandeur d'état diminue, soit dans un deuxième état opérationnel avec une deuxième puissance de compresseur totale, dans lequel la grandeur d'état augmente. Les premier et deuxième états opérationnels se succèdent immédiatement en alternance de sorte qu'une transition du deuxième état opérationnel au premier état opérationnel se produise lorsque la grandeur d'état mesurée devient égale ou supérieure à une première valeur de seuil, qu'une transition du premier état opérationnel au deuxième état opérationnel se produise lorsque la grandeur d'état mesurée devient égale ou inférieure à une deuxième valeur de seuil, et qu'une différence entre la première valeur et la deuxième valeur corresponde à la plus grande des différences de grandeurs d'état qui se produisent au cours de la durée minimale correspondante dans le premier état opérationnel ou dans le deuxième état opérationnel.
