Maximize Efficiency by Changing the Way Your System Operates
Significant energy savings can be achieved by going beyond updating individual field devices are performing a comprehensive overhaul that fundamentally changes how the HVAC system operates.
While the initial investment may be higher than a simple system tune-up, the long-term benefits are substantial, especially in terms of improved energy efficiency, reduced carbon emissions, and higher cost savings. By changing the entire system, this type of retrofit project can provide a more comfortable indoor environment, have a large impact on sustainability, and affect the long-term efficiency of the facility.
Key benefits include:
- Maximized energy-saving potential
- Fully transparent energy management
- Significant reduction of operating costs and carbon emissions
- Perfectly balanced hydronic system
- Healthier indoor air quality
- Increased property value
Change to a Variable Flow System
Constant flow systems can become inefficient when load profiles change, as they deliver the same flow rate even when the demand changes. This can result in uneven and oscillating operating conditions, thereby negatively impacting energy efficiency and occupant comfort. High maintenance and troubleshooting efforts may also increase operating costs.
Changing to a variable flow system will provide accurate control of the pressure and flow rate to dynamically match the changing demands ensuring consistent operating conditions and improving energy efficiency.
Pressure-independent HVAC systems enable accurate flow and pressure control, allowing the system to respond to changing load profiles and demand. This results in improved energy efficiency, increased occupant comfort, and more flexible demand planning.
Optimizing 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 ValveTM.
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.
Implement Data-Driven Decision-Making
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.
Take Advantage of Demand-Controlled Ventilation
Ventilation systems that are continuously in operation, regardless of the actual demand for fresh air, can lead to unnecessary energy consumption and lower indoor air quality. Higher occupancy typically requires more ventilation to maintain good indoor air quality, while lower occupancy requires less ventilation. Energy-efficient and effective ventilation concepts use Demand-Controlled Ventilation (DCV) with CO2 monitoring to indicate occupancy levels.
The combined multi-sensors for CO2, humidity, temperature, and VOCs help provide optimal indoor air quality. The dual-channel NDIR technology-based CO2 measurement device effectively compensates long-term drift, accuracy, and stability. Belimo's actuators and sensors are part of the complete range of HVAC field devices that constitute DCV systems.
