Unit-Level Controls

The chilled-water supply temperature is usually controlled by the chiller. Most commonly, supply water temperature is used as the sensed variable to permit control of chiller capacity to meet system load demand. Supply- temperature control strategies may be used on either constant- or variable- flow systems. As previously discussed, flow control is executed at the load terminals using three-way or two-way valves, or separate pumps for each coil. Control capabilities run the gamut from slow-acting pneumatic controls, to electromechanical controls, to sophisticated digital controls that use "feed- forward" algorithms tuned to give superior performance.

Chiller control

Today’s chiller controls are capable of doing more than simply turning the chiller on and off. At a minimum, these controls should monitor:

•Safety points, such as bearing temperatures and electrical points, that may cause motor failure when out of range.

•Data points that may cause operational problems if corrective action is not taken. An example is low chilled-water or refrigerant temperature, which may result in freezing in or around the evaporator tubes.

•General points to ensure proper chiller performance and refrigerant containment.
