Title
(EN) OIL CONTROL FOR CLIMATE-CONTROL SYSTEM
(FR) COMMANDE D'HUILE POUR SYSTÈME DE CLIMATISATION
Abstract
(EN)
Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor.
(FR)
L'invention concerne des systèmes et des procédés pour purger un lubrifiant d'un premier compresseur à un second compresseur. Un module de commande reçoit une commande de purge de lubrifiant, ferme le second compresseur dans un mode ARRÊT tandis que le premier compresseur demeure dans le mode MARCHE, empêche le fluide de travail provenant d'une sortie du second compresseur de circuler dans le premier compresseur et permet au fluide de travail comprimé évacué d'une sortie du premier compresseur de circuler dans l'entrée du second compresseur de sorte que le lubrifiant dans le second compresseur circule dans le premier compresseur.
