Dynamic Optimisation of Air Handling Units (AHU) using Physics-guided Machine Learning
(REF: S-0567) |
| Trial Project |
|
| Solution Feature |
- Dynamic optimisation of AHU model is built upon the basis of self-trained physics-guided machine learning (PGML) models using actual operating data
- Optimal control settings for AHUs are determined in real-time based on outdoor air conditions, cooling load as well as occupancy level
- Optimal control settings include fresh air/return air damper position, supply air temperature set point and cooling coil valve position
- Level of occupancy can be determined using a wide range of approaches, including CCTV facial recognition and radar technologies
|
| Trial Application and Expected Outcome |
- Model calibration is conducted using actual operating data to ensure AHU optimisation performance
- Based on the real-time data including outdoor air conditions, cooling load as well as occupancy level, the optimisation search is performed to determine optimal control settings
- Optimal control settings are sent back to the building management system (BMS) for optimisation
- Key indicators, including levels of thermal comfort, CO2 and energy reduction, are established to evaluate the effectiveness of a project
