Chiller Demand Flow Energy Savings – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we help facilities unlock significant energy savings through smart chiller demand flow optimization. By adjusting chilled water and refrigerant flow rates to match real-time cooling demands, our solutions dramatically reduce energy waste—especially during part-load conditions—while maintaining system reliability and performance.

How Demand Flow Delivers Energy Savings

Traditional chiller systems often run at constant flow rates, regardless of actual cooling load. This leads to unnecessary energy consumption, overcooling, and system inefficiencies. With demand flow control, the system uses Variable Speed Drives (VSDs), intelligent sensors, and adaptive algorithms to reduce flow during periods of low demand—minimizing the workload on pumps, fans, and compressors.

Key Strategies for Maximizing Energy Savings

• Variable Speed Pump Control
  Reduces energy use by adjusting chilled water pump speeds in response to real-time demand, rather than operating at full speed.

• Fan Speed Modulation
  Optimizes condenser fan operation based on ambient conditions and head pressure—lowering energy draw during cooler weather.

• Compressor Load Balancing
  Automatically stages or unloads compressors based on actual system needs, reducing overuse and power spikes.

• Delta-T Optimization
  Maintains the ideal temperature differential across the evaporator to avoid over-pumping and inefficiency.

• Smart Refrigerant Flow Control
  Uses electronic expansion valves (EXVs) to fine-tune refrigerant flow, improving part-load efficiency.

Energy Savings Results
