Demand Flow Integration in Air-Cooled Chillers – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we specialize in demand flow integration for air-cooled chillers, helping clients upgrade traditional systems into intelligent, energy-efficient cooling solutions. By integrating variable flow technology and smart control algorithms, we enable your chiller system to adapt in real time to fluctuating cooling demands, enhancing performance while reducing energy consumption and equipment stress.

What Is Demand Flow Integration in Air-Cooled Chillers?

Demand flow integration involves modifying or upgrading an air-cooled chiller system to dynamically control the flow of chilled water and refrigerant based on real-time load conditions. This includes the use of variable speed drives (VSDs), smart sensors, and adaptive control logic to modulate compressors, fans, and pumps, ensuring optimal efficiency at all times.

Key Components We Integrate

• Variable Speed Drives (VSDs)
  Installed on chilled water pumps and condenser fans to regulate flow and airflow based on system demand.

• Delta-T Optimization
  Maintains optimal temperature difference across the evaporator to prevent over-pumping and improve heat transfer.

• Compressor Staging & Control
  Smart algorithms activate and modulate compressors based on part-load requirements.

• Electronic Expansion Valves (EXVs)
  Precisely control refrigerant flow to improve system efficiency during varying load conditions.

• Temperature, Pressure & Flow Sensors
  Installed at key locations to provide real-time data for control decisions.

• Control System Integration
  Seamless connection with existing BMS, PLCs, or standalone intelligent controllers for centralized control.

Benefits of Demand Flow Integration

• Achieve 15–40% energy savings, especially during part-load operation

• Improve chiller COP (Coefficient of Performance) and cooling capacity

• Extend equipment lifespan by reducing mechanical stress

• Provide more stable indoor temperatures and humidity control

• Enable smart building compatibility and support energy compliance (LEED, ESG)

Ideal Applications

• Commercial buildings with variable occupancy patterns

• Data centers, hospitals, and labs requiring precise cooling

• Industrial facilities with intermittent or shifting process loads

• Retrofit projects converting from constant flow to variable flow systems

• Multi-zone or multi-chiller systems needing coordinated load management
