Which outcome occurs when a refrigeration system uses an immiscible refrigerant blend circulating at low temperatures?

💡 Explanation

When immiscible refrigerant blends are used at low temperatures, oil, being denser, separates from the refrigerant due to reduced solubility, accumulating in the evaporator, impairing its performance. Therefore, oil accumulation results, rather than slugging, reduced heat transfer, or increased consumption which depend on pressure, fouling, or airflow problems respectively.
