Elementary Control Systems
The preceding chapters discussed the various control elements or units, and how they function with different types of energy. The next four chapters will consider the application of these units to form combinations or “control systems” for the control of HVAC. (The word “system” becomes somewhat overworked here, applying as it does to both “control systems” and “HVAC systems.” The difference is always clear in context.) This chapter will consider only small segments of the larger overall systems. Each of these is a complete control system within itself, and all large systems are made up of complexes of these elementary systems.
