Intelligent Dynamic Energy-Saving Valve, Large Diameter DN65
In current HVAC (Heating, Ventilation, and Air Conditioning) systems, hydraulic imbalances often occur, leading to uneven heating or cooling, overheating, or overcooling issues. These problems reduce indoor comfort, shorten the lifespan of equipment, and result in significant energy waste.
When the operating conditions of an HVAC system change, pressure-independent control valves can be installed to ensure that these core components receive their designed flow rates. This improves the operational efficiency of the HVAC water system and contributes to building energy savings.
Features
● By setting energy values, the system intelligently adjusts the valve to control flow rate and temperature difference, thereby regulating energy consumption per unit time.
● Efficient control is achieved through a ΔT (temperature difference) manager.
● Optimizing the fan coil temperature difference (ΔT) improves fan coil energy efficiency.
● Data on medium temperature, flow rate, and energy consumption can be collected.
● Tracking and diagnostic functions enable better system maintenance.
● Precise ultrasonic flow sensor is used for accurate measurements.
● PT1000 high-precision temperature sensor ensures accurate temperature measurement.
● Automatic stabilization of flow is achieved for consistent control.
● Equal percentage flow characteristics ensure precise flow regulation.
● Simple integrated installation reduces costs and extends service life.
● Direct flow control with real-time feedback on actual flow rate is provided.
● MODBUS RTU communication protocol is used for seamless integration.
This system integrates advanced technology and intelligent control to optimize HVAC performance, enhance energy efficiency, and ensure reliable operation.
