How Belimo Products Contribute to Healthy Indoor Air Quality (IAQ)
Ensuring the quality of indoor air requires a multipronged approach. Besides system design and regular maintenance, reliable products are essential. Belimo offers a complete and innovative range of HVAC control devices to maintain healthy indoor air while minimising energy consumption. From accurate and dependable sensors to variable air volume (VAV) solutions for demand-controlled ventilation to fast running actuators and the all-in-one Energy ValveTM, our products are complemented by our extensive expertise in providing efficient HVAC system performance. With seamless integration to the BMS and cloud-based connectivity, users gain complete visibility of indoor air quality measurements for continuous monitoring and control.
Sensors for Measurement of Indoor Air Quality
What cannot be measured cannot be controlled. Belimo offers a wide range of room and duct sensors to accurately measure temperature, relative and absolute humidity, enthalpy, dew point, CO2 and VOC. The range includes active and passive sensors. The duct sensors have a robust design that meets NEMA 4X/IP65 requirements.
Active room sensors can be commissioned and diagnosed with the Belimo Assistant App on a smartphone. Thanks to wireless NFC communication, configurations can be made even when the sensors are not powered.
Besides being accurate, Belimo sensors have a short response time and a low drift rate, providing long-term stability. They are tailored for fast, error-free installation and commissioning by offering a unique snap-on housing cover, a detachable backplate, spring-loaded removable terminal blocks, and reverse polarity protection.
VAV Solutions for Demand-Controlled Ventilation
The air we breathe impacts our health and productivity; therefore, the precise control of airflow is critical in every workspace. Well-designed variable air volume (VAV) systems ensure the proper amount of fresh air is supplied and contaminated air is removed in a controlled manner in the space. Demand-controlled operation helps to maximise energy efficiency with the necessary amount of airflow. Measuring CO2 levels in the room is an excellent way to achieve this as it is a reliable indicator of air freshness. Furthermore, VAV systems enable negative and positive pressure in critical environments, such as isolation rooms.
Belimo's accurate airflow sensors, combined with actuator technology - which has been tested millions of times, provide precise Δp recording and control of the smallest of volumetric flows. Integrating into a building management system forms the basis for controlling the fan load equally in a cost-optimized way.
Belimo Energy Valve™for Integrated Thermal Energy Management
The correct conditioning of the supplied air is essential for healthy indoor air. This can be achieved by optimising energy efficiency at the same time.
The award-winning Belimo Energy ValveTM is the perfect example of a Belimo innovation combining intelligence with an actuator, flow sensors, and a ball valve. This combination goes well beyond PI control to solve low delta T syndrome and offer flow and power control. Addressing the prevalent low delta T syndrome helps improve energy efficiency and significantly lower the overall performance cost. The tightly closing valve prevents leakage and ensures precise and stable control.
The new generation Energy Valve combines energy control with MID certified energy metering in one device, assuring high accuracy and reliability, allowing for easy and efficient billing and transparent thermal energy management. Digital access supports easy setup or adjustments, commissioning, and maintenance using NFC and the Belimo Assistant App or a webserver providing full transparency to the end user's energy data.
With BACnet/IP or MSTP, Modbus TCP, or RTU on board, the Energy Valve can communicate directly to the BMS. The Ethernet interface enables direct and secure cloud connection while power over Ethernet (PoE) eliminates the need for an extra power supply.
Damper Actuators for a Variety of Conditions
Damper actuators are essential for healthy indoor air as they are required for ensuring reliably functioning HVAC systems.
- Air intake to control the proper amount of outdoor air.
- Inside the air handling unit to control supply, return, and recirculated air.
- Zone to control ensures the proper amount of fresh air based on the demand and air inlets, ensuring the desired airflow pattern.
Air damper actuators were Belimo's first product innovation over 45 years ago. Thanks to continuous technological advances in the HVAC industry, Belimo is a market leader.
Seamless Integration in Building Management Systems and IoT Platforms
Integrating digital communication into devices and equipment provides flexibility in creating innovative HVAC solutions that can control, monitor, and or maintain from anywhere. Building Management System (BMS) operators benefit from device data that is easily accessible for monitoring and system control. Facility managers gain valuable insights into equipment operation and performance, along with access to all device data, enabling timely fault detection and aiding in system diagnostics. Tenants want to be able to minimise energy consumption and cost based on usage.
Belimo products support the open communication protocols Modbus, BACnet based on RS485 or TCP/IP*. Belimo's IoT-ready products can connect to modern building IoT platforms parallel to Building Management System connectivity, offering inputs to transfer sensor measurement values to the digital ecosystem, saving extra I/O-points. With the powerful and secure client Application Programming Interface (API), third parties can integrate Belimo's IoT devices into an OEM's ecosystem, open BIoT platform, or develop their services.
Together, these high quality products ensure the comfort, energy efficiency and safety of people and their property while also ensuring easy installation and reduced maintenance.
