2 Eight Core Product Advantages
1 Global AI Optimization, 20%-40% Total Energy Saving
Different from traditional fixed logic group control, evolutionary algorithm traverses all working conditions in real time to match optimal unit number, pump frequency & valve opening. Combined with MPC load forecast, the system runs at high efficiency without manual operation, achieving 20~40% power saving for hospitals & shopping malls.
2 Dual-Stage Energy Saving Via Air-Water Closed Loop
Closed linkage between cold source and all terminals: When air handlers / fan coils reduce cooling demand, the system automatically lowers chiller & pump output to realize secondary energy saving, extra 10% efficiency improvement compared with chiller-only control.
3 Auto Rotation Extends Equipment Service Life
Record cumulative running time of each chiller, pump & cooling tower, distribute load evenly and rotate startup automatically to avoid long-time overload aging. All pumps adopt stepless VFD to reduce mechanical impact. Built-in current & temperature self-diagnosis sends early warning for bearing blockage & pipeline cracking, lowering overhaul cost.
4 Three-Tier Distributed Architecture, Stable Offline Operation
Local DDC controller operates independently even when cloud connection fails. Dual communication of local RS485 + Ethernet/4G ensures zero shutdown risk for 24-hour factories & hospitals.
5 Multi-Terminal Cloud Visual Remote Control
Alibaba Cloud monitoring dashboard displays real-time unit status, daily/monthly energy curves & indoor temperature. Users log in via mobile APP, tablet or Web PC to remote switch, adjust temperature & edit timing schedule without on-site staff.
6 Multi-Level Instant Alarm O&M
System sends APP & SMS alert within 15s for overload, filter blockage, abnormal water temp & communication failure. Distinguish minor warning & critical shutdown faults, record complete fault log for quick maintenance, supporting unattended 24/7 chiller room.
7 Full Compatibility With All HVAC Equipment
Unified control for water chillers, hot boilers, chilled / cooling pumps, closed cooling towers, AHU & network fan coils. Cross-brand protocol conversion available for renovation projects without replacing original chillers, only DDC hardware required for energy upgrade.
8 Support Large-Scale Thousands Of Monitoring Points
Single system supports thousands of signal points for shopping malls, hospitals & multi-campus industrial parks. Zoned group management enables independent temperature limit & timing for different areas to avoid idle energy waste.
