Rack Optimization – Job Walk Calculator
Estimate compressor savings from floating suction & head. Add compressors, stage-off bonus (cool months), and print a MarketZero-branded summary.Defaults (~1.7%/°F SST, 2.0%/°F SCT) match compressor maps & ASHRAE / NREL job-walk guidance.
Weight your ΔSST/ΔSCT by % of hours. Cool months % is also used for the staging bonus.
| Label | % of hours | ΔSST (°F) | ΔSCT↓ (°F) |
|---|---|---|---|
Stage-off hours ≈ Cool months % × Days/year × rack default hours/day.
Enter per-compressor amps; override PF/hours if different from defaults.
| # | Amps | PF (opt) | Hours/day (opt) | kW (calc) | Actions |

Rule-of-thumb: raise SST ≈ +1.7%/°F, drop SCT ≈ +2.0%/°F compressor kW reduction.
