Which outcome arises when insufficient heat is supplied to the evaporator of a refrigerant heat pump?

💡 Explanation

When insufficient heat is available, refrigerant doesn't fully vaporize in the evaporator, causing liquid slugging because the compressor isn't designed to compress liquid, potentially damaging valves and pistons. Therefore liquid slugging results, rather than overheating, icing, or decomposition which require different thermal overload mechanisms.
