Variable Demand Flow Air-Cooled Chiller Design – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we specialize in variable demand flow air-cooled chiller design, engineered to deliver maximum cooling efficiency, flexibility, and operational cost savings. By incorporating smart flow control strategies, variable speed technologies, and real-time load responsiveness, our designs ensure that your chiller system adapts precisely to changing cooling demands, without energy waste.

What Is Variable Demand Flow Design?

Variable demand flow design enables an air-cooled chiller system to automatically adjust chilled water and refrigerant flow rates based on real-time thermal load. Unlike fixed-flow systems, this approach uses variable speed drives (VSDs), electronic expansion valves (EXVs), and adaptive control logic to reduce energy use, optimize component operation, and improve overall performance across part-load and full-load conditions.

Core Components of Our Variable Flow Design

• Variable Speed Pumps and Fans
  Reduce power consumption by modulating flow and airflow in response to cooling demand.

• Compressor Load Modulation
  Use scroll, screw, or inverter-driven compressors with smart staging for efficient operation at any load level.

• Electronic Expansion Valves (EXVs)
  Regulate refrigerant flow for precise cooling control and better part-load performance.

• Delta-T Optimization
  Maintain the ideal temperature differential across the evaporator to avoid over-pumping and ensure efficient heat exchange.

• Sensor-Driven Controls
  Monitor temperature, pressure, and flow in real-time to continuously optimize system operation.

• BMS Integration
  Seamless compatibility with building automation systems for remote control, monitoring, and analytics.

Benefits of Variable Demand Flow Design

• Up to 40% energy savings compared to constant flow systems

• Improved chiller efficiency (kW/ton) across varying loads

• Extended equipment life and reduced maintenance costs

• Enhanced occupant comfort or process cooling precision
