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

At EKG M&E Sdn Bhd, we provide precision demand flow balancing services for air-cooled chillers, optimizing the interaction between your compressor, evaporator, and condenser to deliver the most efficient cooling output under varying load conditions. Proper flow balancing ensures that refrigerant and chilled water are distributed according to real-time demand, maximizing energy savings while maintaining system stability and performance.

Why Demand Flow Balancing Matters

• Prevents overcooling or undercooling of zones

• Enhances energy efficiency and part-load performance

• Reduces compressor cycling and system wear

• Ensures stable chilled water temperature and flow

• Improves occupant comfort and process reliability

When to Perform Flow Balancing

• After system expansion, retrofitting, or major component replacement

• During commissioning of new chiller installations

• If experiencing temperature fluctuations or inconsistent zone cooling

• When facing high energy bills or unstable system pressures

• As part of a preventive maintenance or energy audit program

Our Demand Flow Balancing Process

System Assessment
We begin with a full system inspection to understand your current flow distribution, load patterns, and control settings. This includes checking:

• Chilled water pump speed and pressure

• Compressor staging and modulation

• Expansion valve operation

• Flow meters and temperature sensors

Performance Analysis
Using flow meters, temperature loggers, and BMS integration (if available), we evaluate:

• Chilled water and refrigerant flow across the system

• Pressure differentials across coils and piping

• Evaporator and condenser performance under variable load

Balancing Adjustments
We fine-tune key components such as:

• Variable speed drives (VSDs) on pumps and fans

• Electronic or thermostatic expansion valves (EXVs/TXVs)

• Flow control valves on the chilled water loop

• Compressor loading sequences

System Optimization and Testing
Post-adjustment, we validate:

• Stable water temperature at all zones

• Balanced refrigerant flow between circuits

• Efficient compressor operation at different loads

• Reduced short cycling and improved runtime efficiency

Benefits of Demand Flow Balancing

• Reduces energy usage by 10–30%, especially at part load

• Improves system responsiveness and consistency

• Enhances equipment longevity by reducing strain

• Maximizes ROI of your chiller system

• Helps achieve compliance with green building and energy efficiency standards
