Which outcome occurs when a refrigeration system compressor uses a refrigerant with high moisture content?

💡 Explanation

When a refrigerant with high moisture content is used, water freezes in the expansion valve due to the low temperatures achieved during expansion, blocking refrigerant flow. Therefore expansion valve blockage results, rather than overheating, corrosion, or inefficiency which stem from different sources.
