Which consequence can result due to refrigeration system icing?

💡 Explanation

Icing causes compressor lubrication starvation because the refrigerant vaporizes poorly, flooding the compressor with liquid refrigerant; therefore, proper lubrication degrades, rather than subcooling changes or increased expansion, to safeguard the compressors.
