⚙️ Series Counterflow Dual Chillers (Lowering Compressor Lift on Lead Chiller)

Series-Counterflow Dual Chiller Calculator

Size series-counterflow dual centrifugal chiller configurations (Trane / Carrier / York): calculate overall plant efficiency gains (routing chilled water and condenser water in opposite directions to reduce thermodynamic lift on both chillers, improving plant efficiency by 8-12% compared to parallel arrangements), and mechanical engineering yields.
