Refrigeration Tonnage at 58% target load share for the plant: a worked example

Suppose target load share for the plant falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Compare measured refrigeration load to installed tonnage so refrigeration technicians can see how much capacity is already committed.

The inputs for this scenario

  • Measured refrigeration load: 180 tons (held at the documented default)
  • Installed chiller plant capacity: 240 tons (held at the documented default)
  • Target load share for the plant: 58 % (the input this scenario stresses; the baseline uses 80)

Working through the calculation

  • The calculation starts from the formula this tool documents: Refrigeration tonnage load share = measured refrigeration load ÷ installed refrigeration capacity × 100.
  • Refrigeration tonnage load share works out to 75 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -17 points at these inputs.
  • Measured utility amount works out to 180 count at these inputs.
  • Reference utility amount works out to 240 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target load share for the plant sits at 80% and the headline result is 75 %, this scenario lands almost exactly on the baseline at 75 %.
  • It computes measured refrigeration load as a percentage of installed capacity, then compares that to your target load share to report the gap in percentage points. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Refrigeration tonnage load share: 75 % (headline result)
  • Gap to target: -17 points
  • Measured utility amount: 180 count
  • Reference utility amount: 240 count
