Title
(EN) CONTROLLING REFRIGERATION COMPRESSION SYSTEMS
(FR) COMMANDE DE SYSTÈMES DE COMPRESSION DE RÉFRIGÉRATION
Abstract
(EN) A refrigerant compression system and method for controlling a refrigerant compression system are described. In some aspects, the refrigerant compression system includes a compressor system having a plurality of compression stages, a plurality of quench valves, a first suction temperature control circuit associated with a first quench valve, a second suction temperature control circuit associated a second quench valve, and a discharge temperature control circuit associated with a plurality of the quench valves. Quench valve settings are determined based on evaluation of one or more outputs from the suction temperature control circuits and the discharge temperature control circuit.
(FR) La présente invention concerne un système de compression de réfrigération ainsi qu'un procédé permettant de commander un système de compression de réfrigération. Selon certains aspects, le système de compression de réfrigération comprend un système de compresseur doté d'une pluralité d'étages de compression, d'une pluralité de vannes de détente, d'un premier circuit de commande de température d'aspiration associé à une première vanne de détente, d'un second circuit de commande de température d'aspiration associé à une seconde vanne de détente, et d'un circuit de commande de température de décharge associé à une pluralité de vannes de détente. Le réglage des vannes de détente est déterminé en se basant sur l'évaluation d'un ou plusieurs résultats de sortie des circuits de commande de température d'aspiration et du circuit de commande de température de décharge.
