Which risk significantly increases following a malfunction in a binary vapor cycle power plant?

A)Turbine blade icing at cold end
B)Ammonia condenser pressure limit exceeded
C)Refrigerant pump motor winding failure
D)Cycle thermal efficiency begins to drop

💡 Explanation

Exceeding the condenser's pressure limit will occur because a cooling system failure prevents condensation and pressure rises during the heating phase. The increased pressure triggers runaway positive feedback, therefore a dangerous explosion becomes a risk, rather than efficiency drop under control.
