Which outcome occurs when an air conditioning system with R-410A refrigerant experiences significant water contamination?

💡 Explanation

When water contaminates R-410A refrigerant, ice crystals form when the refrigerant expands through the capillary tube because the temperature drops below freezing point of accumulated water, leading to blockage. Therefore capillary tube ice blockage results, rather than oil dilution, heat transfer issues, or improved efficiency, which involve different processes.
