Which risk increases when a refrigeration system uses a refrigerant blend with zeolite desiccant?

💡 Explanation

When using refrigerant blends, zeolite desiccant can preferentially adsorb certain components because refrigerant fractionation modifies liquid composition, potentially causing stratification. Therefore stratification risk is the most elevated, rather than overheating, corrosion, or freezing, which arise from different contamination mechanisms.

• Which risk increases most rapidly when a residential heat pump's refrigerant charge drops below specified levels during peak summer?
• Which outcome occurs when a multi-element Yagi-Uda antenna's driven element is poorly impedance matched?
• In a robot arm performing repetitive welding, which consequence results when joint encoder resolution is insufficient?
• Which risk increases when a gallium arsenide (GaAs) semiconductor laser's pulsed operation frequency rises excessively, approaching material limits?
• Which action occurs when differential current protection detects imbalance within a power transformer?
• Which thermal effect occurs when a thermistor's self-heating exceeds its dissipation rate in an air-conditioning unit?
