← ScienceWhich outcome arises when a refrigeration system experiences adiabatic throttling outside design conditions?
A)Decreased evaporator cooling effectiveness✓
B)Increased compressor discharge superheat
C)Lower condenser heat rejection rate
D)Refrigerant subcooling within the condenser
💡 Explanation
Decreased evaporator cooling effectiveness appears when adiabatic throttling malfunctions because the Joule-Thomson effect differs significantly from its design pressures and temperatures. This causes insufficient cooling, therefore sub-optimal heat extraction develops, rather than increased heat or condenser performance.
