VC-21-C063 — Easing Transitions between Flat Plate and Chiller
Implementing various control strategies on the chilled water temperature setpoint will increase waterside economizer run hours and ease the transitions between chiller and economizer modes.
Controlling the chilled water temperature setpoint far lower than normal operation improves chiller operation while the condenser water sump cools enough to maintain the temperature setpoint and cooling load.
Controlling the chilled water temperature setpoint based on what the chiller is doing currently versus what it needs to do eliminates the risk of peaking the machine or pulling too many amps trying to recover a building that does not need recovering.
The warmer the chilled water temperature setpoint can be the more efficiently chillers operate, the more economizer hours are available, and the easier the transition between mechanical and economizer cooling is.
