Which outcome occurs when a scroll compressor in a heat pump operates with superheated refrigerant at the inlet?

💡 Explanation

When the refrigerant is superheated, it absorbs additional heat even before compression starts. This reduces the subsequent temperature rise during compression in scroll compressor because the temperature difference is minimised leading to reduced discharge temperature. Therefore reduced temperature and efficiency results, rather than increasing bearing issues, elevated motor current, or decreased compressor performance under usual operating range.
