Intelligent Valve from Siemens maximizes flexibility and efficiency of HVAC plants
WLAN connection for more flexibility
The Intelligent Valve can be commissioned
automatically, quickly and safely. The required settings can be downloaded into
the Siemens ABT Go app and from there to each valve via wireless LAN. It offers
remote access via BACnet-IP using the Siemens ABT Site commissioning tool or
via the Internet using the Building Operator app. Thanks to its cloud
connection and firmware updates, the Intelligent Valve can
automatically update itself
when needed, ensuring its running on the latest version at all times. If the
valve registers irregular values, an alarm is triggered in the Building
Operator app. In addition, this Siemens cloud app allows users to check the
values and create energy reports for documentation purposes.
Efficiency boost during operation
Functionality and usability enhancements
make the Intelligent Valve even more efficient. As a 3-port valve, it can now
be used in mixed circuits, which offer easy hydronic balancing and require only
minimal investments due to the absence of a main pump in the source circuit. A
new differential pressure control counteracts pressure fluctuations in zones.
In older plants, this allows dynamic hydronic balancing to be upgraded quickly
and easily without having to replace all the valves, thus expanding the scope
of application of the Intelligent Valve. In new plants, the zones equipped with
differential pressure control offer optimized operating conditions for the
valves. Using newly-added flow temperature controls and weather-compensated
heating circuits, the Intelligent Valve performs automation level tasks and
reduces the load on or even eliminates the need for comfort controllers. By
reducing the load on comfort controllers, the Intelligent Valve allows more
complex plants to be installed at lower investment costs. In situations where
comfort controllers are replaced altogether, the Intelligent Valve can perform
simple control tasks.
Newly available spacers for the Intelligent
Valve ensure improved insulation, for instance, for the flow sensor in cooling
applications. The newly implemented Delta-T (DT) limitation control, which is primarily suited for air conditioning units and large fan coil units, offers increased efficiency. This feature limits the temperature difference DT across the cooling coil controlled by the Intelligent Valve. As a result, the chiller or the heating pump always operates above the defined DT - design, ensuring maximum efficiency and saving electrical energy.
