Siemens Smart Infrastructure completes its product offering for HVAC installations with Smart Valves, its first self-optimizing dynamic valves connected to the cloud. Comprising a 2-way control valve, a high-resolution actuator, an ultrasonic flowmeter, two temperature sensors and an intelligent control box, these smart valves improve the energy efficiency of installations, according to the manufacturer, and reduce energy consumption and operating costs throughout their lifecycle. From design to operation, installation and commissioning, they offer numerous advantages, providing "unparalleled efficiency and flexibility."
Energy efficiency
Dynamic intelligent valves continuously monitor temperature, flow and hydraulic power in heating units or air handling units. Using the measured values, the control box ensures that the settings correspond to the heating or cooling behavior of the heat exchanger, or if this is not the case, adapts automatically. This stable control results in energy savings of up to 25 %, guaranteeing greater energy efficiency in HVAC systems.
By dynamically compensating for all pressure variations, intelligent valves ensure a stable room temperature in the building, enhancing user comfort. Manual balancing valves, flow limiters and complex hydraulic calculations become superfluous.
Easy installation and commissioning
Time constraints, design changes and interdependencies are common in HVAC system design. Thanks to their great flexibility, intelligent valves can be installed and commissioned quickly and easily. In fact, the flow sensor, valve and control box can be mounted separately, depending on the space available. To save space, the flow sensor can be installed on the flow side and the valve on the return side. The control box can be positioned parallel or perpendicular to the pipes, or even wall-mounted. What's more, color-coded connectors make it easy to connect the components. Once the valves have been installed, commissioning can be carried out quickly and securely using the free Siemens "ABT Go" application and a WLAN connection. All parameters can then be accessed via this application, but can also be consulted and adjusted if necessary with the "ABT Site" software in BACnet IP, or via a connection to the cloud.
