Which outcome occurs when rapid cycling of a chiller evaporator causes excessive superheat?

💡 Explanation

Oil starvation occurs through refrigerant flood-back because the rapid cycling prevents complete evaporation; this slugs liquid refrigerant and oil back to the compressor, because gravity oil return requires sufficient time rather than continuous full evaporation.
