Solution Details
HVAC Intelligent Energy-Saving Control System Solution
The HVAC Intelligent Energy-Saving Control System Solution is a cutting-edge, AI-driven platform designed to significantly reduce energy consumption in buildings. By integrating IoT, edge computing, and artificial intelligence, it directly addresses the critical need for building energy efficiency, as HVAC systems typically represent 40-60% of a building's total energy use.
Policy Drivers for Smart HVAC Control
The global push toward carbon neutrality has made building energy efficiency a key strategic focus. In China, national guidelines mandate a 10% reduction in building operational energy intensity by 2025, with intelligent HVAC control identified as a priority technology pathway.
Internationally, standards like ASHRAE 90.1 and the EU's Energy Performance of Buildings Directive (EPBD) are accelerating the adoption of smart building automation. The convergence of IoT, AI, and cloud technologies now enables unprecedented levels of optimization for commercial and industrial HVAC systems.
Core Technology: AI-Driven End-to-End Optimization
Closed-Loop AI Energy Management Cycle
Ecolor Technology's HVAC Intelligent Energy-Saving Control System creates a closed-loop management cycle of "Monitor—Analyze—Predict—Control—Verify." The system utilizes Hero V9 series RTU terminals to collect real-time data from chillers, air handling units, and fan coil units, alongside environmental and weather forecast data.
Deep learning algorithms build advanced thermal load prediction models, capable of forecasting HVAC demand up to 30 minutes in advance, forming the foundation for proactive energy-saving control strategies.
Chiller Plant Optimization
Dynamically adjusts running units based on real-time load, improving comprehensive COP by over 30%.
VFD Pump & Fan Control
Adjusts flow rates precisely based on terminal demand, eliminating energy waste.
Free Cooling Mode
Automatically activates during transition seasons to maximize the use of outdoor air for cooling.
Application Scenarios for Energy-Saving Control
This intelligent energy-saving solution is highly versatile, suitable for a wide range of commercial and institutional buildings. Key application scenarios include commercial complexes, office buildings, hotels, hospitals, schools, and critical environments like data centers and industrial facilities.
For large campuses with multiple buildings, the system's unified management platform enables powerful cross-building energy benchmarking and centralized control, providing a holistic view of energy performance and savings opportunities.
System Architecture: Edge-Fog-Cloud
Scalable Three-Tier Intelligent Architecture
The system is built on a robust three-tier "Edge-Fog-Cloud" architecture for reliability and scalability. At the foundation, a dense network of sensing endpoints provides comprehensive monitoring of the entire HVAC system and indoor environment.
The edge layer, powered by the Hero V9 RTU, handles critical local functions including data preprocessing, multi-brand protocol conversion, and emergency control, ensuring system resilience even during network interruptions.
The cloud platform serves as the brain, hosting the powerful AI algorithm engine, delivering detailed analytics dashboards, managing alarms, and generating automated energy and maintenance reports.
