Abstract
A method and control system for operating a chiller system having a lead compressor and a lag compressor in which the load on the compressors is balanced by limiting the % KW demand on the lag compressor from exceeding the 90 KW of the lead compressor while forcing the lag compressor to supply chilled water at a temperature lower than the lead compressor chilled water.
