← ScienceWhich risk increases when exceeding the Carnot cycle's isothermal compression constraint within a refrigeration system?
A)Decreased system energy efficiency
B)Increased superheating of refrigerant
C)Compressor mechanical wear accelerates✓
D)Condenser heat exchanger fouling increases
💡 Explanation
Increased mechanical wear accelerates because liquid slugging occurs during isothermal compression within the refrigeration system, meaning liquid enters the compressor. This causes the 'isentropic compression' assumption to invalid, therefore mechanical stress rises, rather than only decreasing efficiency.
