At EKG M&E Sdn Bhd, we implement advanced demand flow control algorithms for air-cooled chiller systems, enabling dynamic optimization of cooling performance based on real-time building or process load requirements. These algorithms intelligently manage chilled water and refrigerant flow to improve energy efficiency, reduce operational costs, and enhance system responsiveness—especially in multi-zone or variable load environments.
A demand flow control algorithm is a smart control strategy that adjusts the operation of chillers, pumps, fans, and valves based on actual system demand. It continuously analyzes sensor data (temperature, pressure, flow rate) and modulates system components to maintain optimal conditions with the lowest energy input.
Variable Flow Regulation
Modulates chilled water and refrigerant flow using VSDs (Variable Speed Drives) on pumps and fans.
Dynamic Setpoint Adjustment
Continuously adjusts evaporator leaving water temperature, compressor staging, and expansion valve behavior based on real-time load.
Compressor Load Balancing
Distributes run time across multiple compressors to prevent overuse and reduce wear.
Sensor Integration & Feedback Loops
Collects real-time data from:
Flow meters
Pressure and temperature sensors
Return and supply water loops
Zone-level thermostats or process demands
Energy Optimization Logic
Minimizes total system kW/ton by automatically selecting the most efficient operating point for each component.
Fault Tolerance & Safety Monitoring
Includes alerts and fallback conditions in case of pressure, temperature, or flow anomalies.
Saves 10–40% in energy consumption, especially at part load
Reduces short cycling and compressor wear
Increases cooling system responsiveness and stability
