Which outcome occurs when centrifugal chiller pump speed decreases below a critical threshold?

💡 Explanation

System efficiency plummets because reduced pump speed impacts refrigerant flow, diminishing the evaporator's heat exchange capacity through decreased fluid residence time. Therefore, efficiency drops, rather than over-compression occuring; heat transfer rates would slow.
