Optimizing Refrigeration and Chiller Systems for Maximum Energy Efficiency

The 3 kEys 

  • Chillers operate most efficiently within specific load ranges, typically between 60% and 80% of their full capacity. 
  • By intelligently distributing the cooling load, chiller sequencing ensures that chillers operate near their peak efficiency points. 
  • A Variable Flow System operates more efficiently by reducing unnecessary pumping and chiller operation.  By modulating the flow of chilled water to match the cooling load, the variable primary flow (VPF) control reduces the workload on pumps and chillers, and can reduce pumping energy by 20-50% compared to traditional constant flow systems. 

Refrigeration and chiller systems are essential for industrial cooling, but their high energy consumption can significantly impact operational costs. When these systems operate outside their optimal load conditions, they become inefficient, leading to increased energy expenses and accelerated we...
