Abstract[English]
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system (100) includes a compressor (104), a sensor system (177), where the sensor system includes one or more sensors (178) configured to detect one or more operating parameters, and a lubricant circulation system (108) configured to supply lubricant (112) to the compressor (104). The lubricant circulation system (108) includes a lubricant circuit (132) configured to circulate the lubricant (112), a lubricant heat exchanger (124) disposed on the lubricant circuit (132) and configured to heat the lubricant (112), and a controller (136) communicatively coupled to the compressor (104) and the lubricant circulation system (108), where the controller (136) is configured to control the lubrication circulation system (108) to heat the lubricant (112) via the lubricant heat exchanger (124) in response to determining the compressor (104) is in a non-operational state based on the one or more operating parameters.[French]
Un système de chauffage, ventilation, climatisation et/ou réfrigération (CVC&R) (100) comprend un compresseur (104), un système de capteur (177), le système de capteur comprenant un ou plusieurs capteurs (178) conçus pour détecter un ou plusieurs paramètres de fonctionnement, et un système de circulation de lubrifiant (108) conçu pour fournir du lubrifiant (112) au compresseur (104). Le système de circulation de lubrifiant (108) comprend un circuit de lubrifiant (132) conçu pour faire circuler le lubrifiant (112), un échangeur thermique de lubrifiant (124) disposé sur le circuit de lubrifiant (132) et conçu pour chauffer le lubrifiant (112), et un dispositif de commande (136) couplé en communication au compresseur (104) et au système de circulation de lubrifiant (108), le dispositif de commande (136) étant conçu pour commander le système de circulation de lubrification (108) afin de chauffer le lubrifiant (112) par l'intermédiaire de l'échangeur thermique de lubrifiant (124) en réponse à la détermination indiquant que le compresseur (104) est dans un état non opérationnel sur la base desdits un ou plusieurs paramètres de fonctionnement.
