Core Scenario Solutions
1
Air Conditioning Fresh Air Unit
• The system supports flexible start-stop strategies, which can be triggered manually with a single button or run automatically according to preset schedules, allowing for more intuitive device control. • Key indicators such as temperature and humidity can be fine-tuned online to dynamically maintain an ideal comfort environment. • The humidification device and fan are interlocked for safety; if any part of the system malfunctions, it will immediately shut down to eliminate hazards. • Real-time monitoring of filter pressure differential sends cleaning reminders when clogged, ensuring clean airflow. • Continuous collection of the temperature at the rear of the cooling coil automatically activates the anti-freezing program when approaching freezing point to prevent coil rupture.

Heating and Cooling Source System
• Intelligent load adjustment: The system continuously monitors the load; if it remains above 90% for 20 minutes, an additional main unit is automatically added; if it stays below 30% for 20 minutes, one main unit is automatically removed, achieving dynamic capacity matching. • Energy-saving optimization: The supply temperature of chilled water is reset in real-time according to terminal demand; when multiple units operate, a rotation strategy is executed to balance the operating time and start-stop frequency of each main unit; variable frequency chilled water pumps adjust flow finely within the 30–50Hz range to reduce delivery energy consumption.

Supply and Exhaust Air, Sump Control
• Sump: Automatically starts and stops the drainage pump based on real-time water levels, and cycles through backup pumps, providing real-time feedback on pump status, manual/automatic operation, and fault information; alarms are triggered when water levels exceed limits. • Supply/Exhaust Fans: Support remote one-button start-stop or operation according to preset schedules; can intelligently link start-stop based on indoor CO₂ concentration, temperature, humidity, and other environmental variables; synchronously monitor fan operation, manual/automatic status, and fault conditions, with immediate alerts for anomalies.
Solution Highlights
• Cost Reduction: Fully wireless LoRa networking eliminates the need for cables and trays, reducing construction and labor costs by 60%. • Speed: Wireless I/O modules are “plug and play,” allowing for single-point deployment in 15 minutes, while traditional solutions require 2 hours. • Flexibility: Devices can be relocated according to scenarios, connecting to the network immediately upon going online, with zero downtime for expansion. • Stability: LoRa DDC peak power consumption is <3W, operating without fans in all conditions from 0–50°C. • Compatibility: Native BACnet/IP, with second-level integration with existing BMS. • Security: Multi-level permissions and operational auditing, isolating fault nodes for continued operation.
Using LoRa wireless as a foundation, we reconstruct the architecture of building automation systems, creating a wireless intelligent control platform that covers heating and cooling sources, air conditioning, ventilation, and water supply and drainage. Through self-developed wireless DDC, edge computing nodes, and cloud AI algorithms, we achieve three major breakthroughs: “zero burden for wireless deployment, high efficiency for intelligent decision-making, and strong security for resilient architecture.”
Wireless technology has become a new paradigm for building automation, continuously deepening the integration of AI and energy management, helping buildings upgrade from “energy-consuming terminals” to “intelligent nodes.”
