← ScienceWhich outcome occurs when a closed ammonia refrigeration system rapidly loses condenser cooling?
A)Compressor overheating from increased load
B)Suction line frosting due to low pressure
C)Expansion valve blockage from ice formation
D)High pressure trip from refrigerant phase change✓
💡 Explanation
When condenser cooling is lost, the refrigerant can't fully transition to a liquid phase, increasing the high-side pressure because energy isn't dissipated. Therefore a high-pressure trip occurs, rather than overheating, frosting or blockage, which require alternative cooling mechanisms or fault modes.
