Which outcome occurs when an evaporator's external frosting condition blocks airflow in a refrigeration system?

💡 Explanation

When external frosting blocks airflow, evaporator pressure drops, causing liquid refrigerant to flood back to the compressor because of reduced vaporization. This phenomenon is known as liquid slugging, leading to potential compressor damage. Therefore compressor failure results, rather than valve or tube damage or increased superheat which depends on different operating conditions.
