Intelligent Valve from Siemens: self-optimizing and connected to the cloud

Intelligent Valve optimizes heat exchangers
Temperature, flow rate and energy are measured continuously. Based on the measurements, the Intelligent Valve checks whether its settings are line with the heating or cooling behavior of the heat exchanger. The valve adjusts automatically, e.g., to changing values caused by contamination during operation, thus avoiding repeated manual readjustments across the life cycle of the system. At the same time, the Intelligent Valve's heat exchanger optimization feature ensures that heating, ventilation and air conditioning (HVAC) systems operate energy-efficiently at all times. For instance, the valve detects the flow rate at which additional energy from the heat exchanger can no longer be efficiently converted into higher heating or cooling output.
Commissioning of the Intelligent Valve is automatic, quick and reliable. Different methods can be used to transfer the datasets to the valve. The twin datasets can be downloaded directly to the valve from the Desigo ABT Site commissioning tool or using the ABT Go app. Connecting the valve directly to the cloud is an even more convenient option, allowing values set during the planning phase to be adjusted later on via remote access. Values can be optimized at any time, even during operation. In addition to wireless LAN and direct cloud connection, the Intelligent Valve offers a third communications interface: BACnet/IP.
Flexible mounting options
Since space is often tight during renovations and modifications, the Intelligent Valve offers very flexible mounting options. To save space, the ultrasonic flow sensor can be installed in the flow and the valve in the return. The controller box can be mounted parallel or crosswise to the pipe, allowing sufficient space for insulation work, or separately on the wall. Color-coded plug-in connectors make connecting the flow sensor, valve and controller box fast, easy and error-free.
The Intelligent Valve's control functions allow for automatic dynamic balancing of the hydronic system, similar to PICVs (pressure-independent combi valves). Dynamic hydronic balancing automatically compensates for pressure fluctuations, thereby avoiding temperature variations in the building and improving the comfort level for building users. There is no need for circuit control valves, balancing throttles or complicated hydronic calculations.
In the Siemens Building Operator cloud application, the Intelligent Valve creates reports with valve settings and energy consumption values. The reports can be viewed at any time and used for system acceptance and energy monitoring. If the valves are integrated into the Desigo building management system, they can be easily adjusted to changing operating conditions. Automated function tests or energy-optimized solutions can be downloaded into the valves later on.
