Variable-speed pump load control

By using a pump for each coil (Figure 7), the flow may be controlled by varying the pump speed. In such systems, there may be no control valves at the coil. This can reduce both the valve and the valve installation costs, but increases coil pump and maintenance costs.

Figure 8 shows a control variation using an uncontrolled or “wild” coil. In this system, control of the conditioned air supply is executed by face-and- bypass dampers that permit a portion of the air to bypass the coil surface. Advantages of this strategy are the elimination of control valves and improved part-load dehumidification. A disadvantage is that all the water is
