A multi-chiller plant with VFD compressors+sequencing is most often optimized in controls to (conceptual)?
Choices
- (A) Run the smallest at 10% 24/7
- (B) Maximize chiller+plant COP by staging to stay near the best kW/ton envelope and to manage lift/condensing conditions
- (C) Use fixed-primary always
- (D) Delete tower approach
Correct answer: (B)
Maximize chiller+plant COP by staging to stay near the best kW/ton envelope and to manage lift/condensing conditions
Explanation
CUP optimization: chiller+aux loads; lift; tower+cond water reset.
