Chiller Condenser Water Reset Savings Calculator — Lift, kW & Annual Energy

Screen chiller power savings from lowering entering condenser-water temperature using measured baseline power and a site-validated percent-per-degree response.

Inputs

Results

Power saved 8.00 kW
New chiller power 392.00 kW
Annual energy saved 40000 kWh
Annual value $4000

Formula

saved kW=Pbase×ΔT×saving factor.

Worked example

A 400 kW chiller with a validated 1%/°C response and 2°C reset screens at 8 kW compressor savings.

Assumptions & limits

  • Tower fan/pump penalties must be evaluated separately.
  • Respect OEM minimum condenser-water temperature and lift limits.

FAQs

What does this Chiller Condenser Water Reset Savings Calculator calculate?

Screen chiller power savings from lowering entering condenser-water temperature using measured baseline power and a site-validated percent-per-degree response.

Is this suitable for final design?

Use it for transparent engineering screening and diagnostics. Verify final design or operating changes against measured site data, OEM curves and applicable standards.

Why are assumptions shown?

Plant calculations depend on operating boundaries. Explicit assumptions make scenarios auditable and prevent false precision.
