Using dedicated equipment for oil recovery and ensuring a clean evacuation of the system before charging new refrigerant and oil are essential steps for preserving efficiency and reliability. Viscosity Selection and Performance Metrics The viscosity grade of a c compressor oil is a crucial specification that determines its flow characteristics.
Heat Dissipation and System Cooling As the compressor operates, it generates significant thermal energy. Manufacturers specify the ideal viscosity, often measured in centistokes (cSt), to ensure proper lubrication across a range of operating conditions.
