Which risk increases substantially when a mixed refrigerant's Reynolds number exceeds a compressor design limit?

💡 Explanation

Lubricant foaming increases because turbulent flow from the Reynolds number limit enhances refrigerant mixing and vaporization; therefore, enhanced foaming results, rather than stable conduction, as boundary layer separation increases wear issues.
