Upgrade your system with better technology
Upgrading an HVAC system with newer technology effectively supports the increasing demand for greater energy efficiency, improved occupant comfort, and healthier indoor air. Updated equipment also supports cost-saving initiatives: Smart, high-quality control components, for example, are more reliable, require less maintenance and experience fewer breakdowns, leading to a longer lifespan for the overall system.
Prevent leakage with tight control valves
Aging and defective control valves challenge the system performance with compromised control accuracy and leakage, thereby leading to uneven heating or cooling as the valve cannot control the flow precisely. For instance, 1% leakage results in a 5 to 10% energy loss. In addition to heightening energy consumption and occupants' discomfort, this lack of control and balancing will also trigger increased maintenance efforts.
It is clear: Reliable control and flow regulation are vital to meet the dynamic cooling and heating loads in buildings. Belimo's Characterized Control Valves (CCV) are tight control valves and have been designed to replace aging valves for a more accurate, responsive, and maintenance-free solution.
Unleash the power of data
Digital communication capability in HVAC devices and equipment – such as cloud connectivity and other digital communication protocols – is essential when providing specific and real-time data necessary to improve energy efficiency and comfort in buildings.
Belimo’s product ranges of smart HVAC field devices, complete with digital communication capability, unlock efficiency potential by providing valuable data for building analytics which lead to more informed decision-making and optimized building performance.
Belimo's advanced technology with Modbus and BACnet enables straightforward system integration and real-time access to device data, helping to significantly reduce troubleshooting time, maintenance costs and system complexity.
Evolve your system to be pressure independent
Buildings are dynamic and constantly evolving as their use and designation change over time. Aging HVAC systems components, renovations, and building extensions can significantly impact a hydronic system's performance. Maintaining and monitoring the accurate flow conditions of the HVAC system is essential for ensuring that the energy is distributed evenly and efficiently throughout the building.
Pressure-independent valve technology plays a crucial role in addressing the unique control challenges of variable flow pumping systems. Belimo offers a series of pressure-independent (PI) control valves from the PIQCV, a compact and tight PI valve; to the EPIV, an electronic PI valve offering flow measurement in real time; to the Energy Valve that optimizes and documents energy consumption of HVAC installations.
Optimising the pump speed of HVAC systems in real-time can help to significantly lower pump energy consumption and improve overall system efficiency. To reduce the speed of a pump, its pressure head needs to be dynamically controlled according to the opening position of the surrounding valves. This pump optimizer functionality can be easily implemented with Belimo electronic pressure independent valves or the Belimo Energy Valve.
Additional savings can be achieved by continuously monitoring the delta T of a hydronic circuit and comparing it to the desired delta T setpoint with the Belimo Energy Valve. Suppose the actual delta T falls below the setpoint for a predetermined period. In that case, the Delta T Manager is activated and adjusts the flow until the delta T is at or above the set minimum.
