The Role of HVAC Controllers in HVAC Systems: Enhancing Efficiency
Commercial and residential facilities of all kinds require modernized HVAC control systems to maintain healthy, safe, and comfortable interior environments. Components like thermostats, sensors, dampers, actuators, and computerized central control units work together to optimize performance and energy efficiency.
Here we’ll take a closer look at these components and how they can be integrated into HVAC systems for improved performance and energy savings.
Integrating Controllers with HVAC System Components
Integrated controllers in HVAC systems use strategically-placed sensors and real-time monitoring tools that track environmental factors, including temperature, indoor air quality (IAQ), and humidity. The sensors transmit data back to one or more HVAC controller units, which function as the system’s brain and coordinate components that adjust airflow, temperature, and moisture, namely:
- Dampers
- Actuators
- Fans
- Heating and cooling elements
User-defined parameters or “setpoints” for temperatures, humidity levels, custom climate zones, schedules, and others are programmed in for the system to target. This information, along with the data gathered by sensors and monitoring equipment, determines when fans, heating or cooling elements, and other parts are turned on or off. As a result, the indoor air quality, temperature, and moisture are maintained without the need for manual adjustments.
Modern control systems also help save energy by timing on and off cycles precisely so equipment runs only as long as necessary. Software that oversees the entire HVAC system allows for remote operation and, if needed, temporary or ongoing changes to setpoints from a single point of access.
How HVAC Systems Benefit Residential and Commercial Buildings
Whether installed in commercial or residential spaces, high-quality HVAC control systems and dampers do more than provide greater comfort. They’re also critical for safety and risk prevention. Some examples include:
- Keeping temperatures within safe ranges for people, products, and equipment
- Isolating or ventilating hazardous fumes/particulates
- Cooling air to reduce moisture and potential mold-growth environments
- Preventing the spread of fire and smoke
- Reducing or muffling sound
Among the most important components in an HVAC system are dampers. These adjustable plates are opened and closed by motorized actuators to either block or facilitate the flow of air from one area to another. They are often placed inside ductwork and in places where two distinct spaces meet, such as interior/exterior walls. With a computerized control system, actuators can be programmed to adjust damper plates based on sensor data, or based on pre-determined schedules.
Choosing the Right Controller for Your System
Choosing the right HVAC control system for a given structure depends on the type of HVAC equipment being used and its existing baseline performance. As control systems, sensors, and actuators become more sophisticated and precise, the fans, dampers, ductwork, and other HVAC components must be responsive and effective enough to keep up. Blowers, fans, A/C, or furnace units, even when controlled by advanced software and sensors, will still have to work hard and use more energy to reach the desired climate parameters if they are inefficient or undersized.
Alan Manufacturing, Inc. helps building owners and residents in many industries derive greater value from their HVAC systems with energy-efficient climate equipment, computerized monitoring and control systems, demand-control strategies, employee training/engagement modules, preventative system maintenance, and whole-system upgrades.
