LUBRICANT MANAGEMENT FOR AN HVACR SYSTEM

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. 公开了用于HVACR系统中压缩机的润滑剂管理的系统和方法。利用工作流体来提供加热或冷却的传热回路包括用于压缩工作流体的压缩机和被配置成增加进入压缩机的工作流体的吸入温度的热源。基于在压缩机轴承腔处或附近进行测量的压缩机系统中的一个或多个润滑剂流变性质是可确定的。润滑剂贮存器可以与压缩机的排放流动路径热连
