Chilled Water System Balancing Services

1. System Review and Assessment

• Conduct a thorough assessment of the chilled water system, including reviewing existing equipment such as pumps, chillers, FAHU’s (Fresh Air Handling Units), AHU’s (Air Handling Units), FCU’s (Fan Coil Units), valves, etc.
• Check the capacity, flow rates, and temperature differences at various points of the system to evaluate system performance.

2. Flow Measurement

• Measure flow rates at key points in the system, including at the chillers, cooling coils, branches, FAHU’s, and AHU’s.
• Utilize flow meters or other precise instruments to ensure accurate flow readings for effective balancing.

3. Balancing the System

• Adjust the flow of chilled water to ensure proper distribution across all branches, coils, and units.
• Adjust control valves, balancing valves, and other related equipment to achieve the desired flow and temperature distribution.
• Fine-tune each section to ensure optimal performance and prevent over- or under-cooling in the system.

4. Temperature Monitoring

• Measure and verify the temperature differentials across the system (supply and return temperatures) to ensure the system is running within design specifications.
• Ensure that the system maintains the required cooling setpoints and temperature differences for efficiency.

5. Pump and Valve Adjustments

• Ensure that pumps are operating within their design parameters (e.g., flow rates, pressures) to maintain system efficiency.
• Adjust balancing valves, pressure-reducing valves, and other components to optimize flow rates and pressures, ensuring proper system operation.

6. System Optimization

• Monitor the chilled water system’s performance under varying load conditions to assess operational stability.
• Adjust system settings for energy efficiency, focusing on part-load operations to minimize energy consumption while maintaining comfort levels.

7. Insulation and Civil Work

• Ensure any insulation removed from chilled water pipes during maintenance or adjustments is properly replaced and secured to maintain system efficiency.
• Ensure any access points created for system adjustments or inspections are securely fixed and restored to their original condition.
• If any civil work is required (such as ceiling openings, repairs, or structural adjustments), ensure it is included in the scope and completed to the necessary standards.

8. Full Building Coverage

• Ensure the chilled water balancing process covers the entire building, including common areas, apartments, and shops.
• All HVAC systems within the building, whether in residential or commercial spaces, will be included in the balancing and optimization process.

9. Reporting and Documentation

• Document all measurements, adjustments, and settings for reference and future troubleshooting.
• Provide a comprehensive report outlining any issues identified during the balancing process and include recommendations for system improvements or upgrades.

10. Post-Balancing Review

• Conduct a post-balancing review to verify system performance after adjustments, ensuring stable flow rates and temperature control.
• Monitor system performance over a specified period to confirm that no further adjustments are necessary.

Building Air Balancing Services

1. Inspection & Assessment

• Inspect FCUs (Fan Coil Units), FAHUs (Fresh Air Handling Units), ducts, dampers, and vents for blockages, leaks, or inefficiencies.
• Measure air supply, return air flow, and static pressure at critical points in the system to assess airflow performance.

2. Adjustments & Corrections

• Regulate damper settings and fan speeds to ensure balanced and consistent airflow across the system.
• Seal any air leaks and ensure vents and grilles are operating correctly to avoid energy losses and inefficiencies.

3. Holes and Access Points

• Ensure that any holes made in ducts for access during inspection or adjustments are properly sealed to prevent air leakage.
• Address any openings or access points created for maintenance and restore them to their original condition.

4. Full Building Coverage

• Perform air balancing across the entire building, ensuring proper airflow in all common areas, apartments, and shops.
• Ensure all HVAC systems in the building are balanced, including those in residential and commercial spaces.

5. Testing & Verification

• Re-measure airflow after all adjustments to confirm the system is properly balanced.
• Monitor and record temperature and humidity levels to ensure consistent comfort in all areas.

6. Final Report & Recommendations

• Provide a summary of airflow readings before and after the balancing adjustments.
• Offer additional recommendations or improvements if needed to further enhance system performance and efficiency.

7. Civil Work and Duct work (if applicable)

• Include any civil work required, such as repairing or sealing ductwork, access points, or structural repairs related to air balancing services.
