  • Optimized selection of dissimilar chillers
    Patent number: 4463574
    Abstract: 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 head of the chillers, and a controller connected to the load sensor and to the refrigerant head sensor for sorting the chillers according to their efficiency characteristics 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.
