2.2.24 Convert the primary/secondary chilled water plant to variable flow primary

Description

Evaluate the opportunity to remove the primary chilled water pumps, and use the secondary pump (which can be resized as needed) as the variable flow primary pump with a modified control sequence.

Benefits

  • Less space required

  • Reduce pump peak power

  • Lower pump annual energy usage

Limitations

  • The complexity and possible failure of the bypass control

  • The complexity and possible failures associated with chiller staging

Economic assessment

Lower first costs and lower pump energy costs.
