Which outcome occurs when a scroll compressor overheats excessively in a heat pump system during operation?

💡 Explanation

When a scroll compressor overheats, lubricant thermal decomposition occurs because high temperatures accelerate chemical reactions, producing breakdown products including acids that contaminate the refrigerant. Therefore refrigerant breakdown results, rather than bearing failure, cooling increase, or efficiency gain each requiring very different mechanisms.
