OPTIMIZED SELECTION OF DISSIMILAR CHILLERS

摘要

A system for meeting building air conditioning load conditions by optimally selecting a combination of chillers having dissimilar efficiency characteristics, the system having a load sensor for sensing building load a refrigerant head sensor for sensing refrigerant bead of the chillers, arld a controller connected to the load sellsor and to the refrigerant head sensor for sorting the chillers according to their efficiency characteristic data with the chiller having a minimum kw/ton versus capacity point being ranked first and for selecting a combination of the chillers which will require a minimum energy input to meet building load conditions.
