Title
(EN) LUBRICANT MANAGEMENT FOR AN HVACR SYSTEM
(FR) GESTION DE LUBRIFIANT POUR SYSTÈME HVACR
Abstract
(EN)
Systems and methods for lubricant management of a compressor in an HVACR system are disclosed. A heat transfer circuit can utilize a working fluid to provide heating or cooling includes a compressor for compressing the working fluid and a heat source configured to increase a suction temperature of the working fluid entering the compressor. One or more lubricant rheological properties in a compressor system based on measurements taken at or near a bearing cavity of the compressor are determinable. A lubricant reservoir can be in thermal communication with a discharge flow path of the compressor. An internal heat exchanger can be disposed within a compressor for improving viscosity of the lubricant to be cycled back into the compressor. A heater can be located on a fluid line between a lubricant separator and a lubricant inlet. Condenser fans can be controlled.

La présente invention concerne des systèmes et des procédés de gestion de lubrifiant d'un compresseur dans un système HVACR. Un circuit de transfert de chaleur peut utiliser un fluide de travail pour fournir un chauffage ou un refroidissement et comprendre un compresseur pour comprimer le fluide de travail et une source de chaleur conçue pour augmenter une température d'aspiration du fluide de travail qui entre dans le compresseur. Une ou plusieurs propriétés rhéologiques de lubrifiant dans un système de compresseur peuvent être déterminées sur la base de mesures prises au niveau ou à proximité d'une cavité de palier du compresseur. Un réservoir de lubrifiant peut être en communication thermique avec un trajet d'écoulement de décharge du compresseur. Un échangeur de chaleur interne peut être disposé à l'intérieur d'un compresseur pour améliorer la viscosité du lubrifiant à recycler pour revenir dans le compresseur. Un dispositif de chauffage peut être situé sur une conduite de fluide entre un séparateur de lubrifiant et une entrée de lubrifiant. Des ventilateurs de condenseur peuvent être commandés.
