SYNOPSIS
Dynamic Air Conditioning Systems represent a cutting-edge approach to ACMV design, prioritizing and digitising the large scale project room load calculation, waterside and airside configuration, integration of energy efficiency, parametric green rating selection, occupant comfort, and adaptability to changing environmental conditions. By incorporating advanced control strategies and intelligent sensors, these systems optimize performance in real-time, significantly reducing energy consumption and operational costs.
The talk will emphasize on the various techniques of ACMV system on high performance buildings like Hospital, Pharmaceutical, Data Center, Warehouse and etc with the following Key Principles and Components:
1. ACMV Simulation :
• Dynamic Simulation Tools: Performing and digitisation of ACMV design enables system
optimisation, resilient waterside and airside plant configuration in compliance to the
international standards during design stage.
2. Control SetPoint and Real-Time Monitoring:
• Sensor Networks: Control strategy and setpoint are required for the network of sensors to
monitor the indoor and outdoor conditions, including temperature, humidity, CO2 levels, and
occupancy in 24hours system analysis.
3. Variable Air Volume (VAV) Systems:
• Zone-Based Control: VAV systems deliver conditioned air to specific zones within a building,
allowing for precise temperature and airflow control while performance better energy efficiency.
• Demand-Driven Ventilation: Ventilation rates are adjusted based on occupancy and indoor air
quality, reducing energy waste.
4. Energy-Efficient Equipment:
• High-Efficiency ACMV Units: Employing energy-efficient chillers and AHU fan minimizes energy
consumption.
• Variable Speed Drives (VSDs): VSDs optimize the operation of motors, reducing energy usage.
5. Integration with Building Automation System:
• Centralized Control: BAS integrates ACMV systems for holistic energy management.
• Predictive Control: Leveraging historical data and weather forecasts, BAS can predict future loads
and optimize system operation.
6. Innovative Technologies:
• Heat Recovery Systems: These systems capture waste heat from exhaust air to preheat incoming
air, improving efficiency such as DOAS AHU.
• Air or Water-Source Heat Pumps: These systems use water as a heat source or sink, providing
efficient heating and cooling.
• Renewable Energy Integration: Incorporating renewable energy sources
(e.g., solar for reheating) can further enhance the ACMV system efficiency
Benefits of Dynamic Air Conditioning Systems:
• Energy Efficiency: Significant reduction in energy consumption and operational costs.
• Improved Indoor Air Quality: Enhanced air quality through optimized ventilation and
filtration.
• Enhanced Occupant Comfort: Personalized comfort settings and reduced thermal discomfort.
• Reduced Environmental Impact: Lower greenhouse gas emissions and reduced ecological
footprint.
• Increased Building Value: Modern, energy-efficient systems can increase property value.
By embracing dynamic air conditioning system design, building owners and operators can create more sustainable, comfortable, and cost-effective environments.
