With apologies to Aretha Franklin, it’s time to show valves, actuators and sensors a little R-E-S-P-E-C-T. These control devices are the key to a holistic heating, ventilation and air conditioning (HVAC) system. When each component within a building management system (BMS) lives up to its potential, the maximum amount of time, energy, water and other precious resources is saved. That can translate into HVAC system energy savings of 40 percent.
Another benefit of a holistic Building Management System – greater comfort due to more localized control of the HVAC system.
Field devices don’t always get the credit they deserve for the role they play. But, trust me. When valves, actuators and sensors aren’t happy, the whole control system isn’t happy.
With the right design, a controller failure doesn’t deliver scalding water to someone washing his or her hands. Instead, when the controller is out of commission, the field devices make sure that nobody gets burned by sending out a safe-temperature flow. That’s done by setting a desired position, one that mixes in enough cold water with the hot to prevent problems.
That is one way modern valves, help make a holistic HVAC system a reality. So, keep in mind the need to focus on field devices as the foundation of a strong BMS, delivering comprehensive integrated control to the HVAC solution. If you do, you’ll be the one earning respect.
