Which outcome results during each iteration of a vapor-compression refrigeration cycle with increased superheat?

💡 Explanation

When superheat increases, more heat is absorbed by the refrigerant vapor before compression because there's is greater temperature difference, so the compressor must work harder. That excess heat is then dumped meaning more heat is rejected by the condenser. Therefore, increased heat rate results, rather than low capacity which requires lower compressor work.
