The CoolLogic Control System governs all top level events, timing and compressor staging, and allows operator interface for all levels of setting and retrieving data.  It provides a leaving chilled solution temperature control algorithm which maintains accurate temperature control, for both comfort and process applications. A compressor run time equalization sequence is given to ensure even distribution of compressor run time throughout the entire chiller bank. Chiller power consumption is minimized by indexing the most efficient stages of cooling, optimizing heat transfer surface.
