← ScienceWhich consequence results when a refrigeration system experiences refrigerant phase transition above design pressures?
A)Reduced compressor lifespan expected✓
B)Improved coefficient of performance obtained
C)Increased subcooling occurs downstream
D)Heat exchanger efficiency rises
💡 Explanation
Compressor lifespan diminishes because liquid refrigerant entering the compressor during high-pressure vapor condensation causes liquid slugging resulting in mechanical damage; therefore, shorter lifespan, rather than improved performance, will occur because damage happens before optimal efficiency.
