Shanghai Logistics CxA
Comprehensive commissioning and performance evaluation at Luman Garden to resolve HVAC performance issues, validate design intent, and ensure sustained system efficiency and reliability across logistics operations.
Detailed Assessment
- Analyzed existing chiller plants, distribution networks, and emission points.
- Reviewed sequences of operation, setpoints, and seasonal changeover logic.
- Checked hydraulic schematics and valve authority across critical circuits.
Performance Evaluation
- Verified chiller performance against design/manufacturer specifications.
- Benchmarked COP/EER, ΔT across heat exchangers, and pump specific power.
- Assessed ventilation effectiveness and heat recovery efficiency.
Diagnostic Testing
- Tested temperature/pressure sensors, flow detectors, and control loops.
- Performed functional tests on AHUs, pumps, valves, and safeties.
- Validated alarms, trend logs, and BMS data points for accuracy.
Maintenance Review
- Evaluated preventive maintenance practices and critical spares.
- Defined calibration intervals for sensors and meters.
- Outlined seasonal recommissioning and performance checklists.
System Optimization
- Proposed balancing valve installations and hydraulic rebalancing.
- Refined control strategies (reset schedules, staging, night/setback).
- Optimized heat recovery settings and ventilation control.
- Indoor lighting renovation in selected zones to reduce cooling load.
Efficiency Improvement
- Action plan to sustain efficiency via monitoring and targeted KPIs.
- Operator training on controls, alarms, and best-operating practices.
- Roadmap: no/low-cost actions first, followed by targeted CAPEX.
Outcome: Optimized HVAC operation with improved comfort, reliability, and measurable energy performance, aligned with the site’s sustainability goals.
