Which outcome predominates when a refrigeration system employs refrigerant with excessive dissolved air?

💡 Explanation

When refrigerant contains excessive dissolved air, reduced cooling capacity occurs because the non-condensable gases displace refrigerant volume and increase its partial pressure inside the condenser, inhibiting effective heat transfer. Therefore cooling is reduced, rather than elevated temperatures, pressures, or ice formation since those involve different mechanisms and system conditions.
