Demand Flow Chilled Water System Integration – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we specialize in demand flow chilled water system integration, enabling your cooling system to respond dynamically to real-time building or process loads. By integrating variable flow technology, smart controls, and system-wide synchronization, we help businesses achieve exceptional energy efficiency, precise temperature control, and long-term operational savings.

What Is Demand Flow Chilled Water Integration?

Demand flow integration involves configuring your chilled water system—pumps, valves, chillers, and control logic—to automatically adjust flow based on actual cooling demand. Instead of running at a fixed speed or delivering constant water volume, the system adapts its operation, ensuring optimal thermal performance and minimal energy consumption.

Key Components of Integration

• Variable Speed Pumps (VSDs)
  Control pump speed to regulate chilled water flow in real time.

• Delta-T Optimization
  Maintain target temperature differential across the evaporator to ensure proper heat transfer and avoid over-pumping.

• Flow and Temperature Sensors
  Monitor system conditions (supply/return temps, flow rate) to feed data into the control logic.

• Pressure-Independent Control Valves (PICVs)
  Allow precise zone control regardless of system pressure fluctuations.

• Electronic Expansion Valves (EXVs)
  Modulate refrigerant flow for consistent and efficient evaporator performance.

• Smart Chiller Controls & PLC Programming
  Coordinate chilled water flow with compressor staging, fan operation, and building load conditions.

Benefits of Demand Flow System Integration

• Up to 30–40% energy savings in part-load operation

• Enhances chiller performance and system COP (kW/ton)

• Reduces pump energy usage and over-circulation

• Improves comfort control across all zones

• Extends equipment life by reducing mechanical stress

• Enables real-time monitoring and BMS integration
