The other headings are condenser water flow in gpm and gpm/ton, chiller LIFT, condenser water temperature rise, CWr, condenser water return temperature, CR, the incremental change in condenser water temperature rise, dCWr
, the incremental change in chiller LIFT which is 60% of dCWr
, the power into the pump variable speed drive, kWp, the pump efficiency, kWp/ton, and the incremental change in pump efficiency, dkWp/ton.
