Dynamic Differential Pressure Control Cabinet for HVAC and Water Systems
Application:
• Under the framework of Building Automation System (BAS/BA), this control cabinet can be integrated as a sub-module of the water system, and upload data such as differential pressure, flow rate, and pump speed through communication interfaces (e.g., BACnet, Modbus, Ethernet).
• It is installed in machine rooms, pump rooms, electrical control rooms, etc., to facilitate centralized monitoring, remote diagnosis, and implementation of energy-saving strategies.
• It is particularly suitable for integrated projects that require energy saving (e.g., green building certification), equipment intelligence, and visual monitoring.
• Summary: The application scenarios are concentrated in water circulation systems (HVAC central heating/central chilled water), building electromechanical systems, and district energy supply systems. The key lies in working conditions such as "multiple terminals/multiple branches" + "variable load" + "the system needs to maintain differential pressure".
