Refrigeration Performance Intelligence
Continue from a completed Design-vs-Field comparison. Apply only your explicit OEM, Project or commissioning tolerances, identify deterministic investigation patterns, enter the right Issue Finder workflow and define what must be retested.

WHEN TO USE THIS TOOL
Useful during reference & conversion work.
- Resolve unit-system differences quickly across calculations, drawings, schedules and vendor data.
- Look up common formulas, constants and engineering reminders without leaving the HVACR workspace.
- Reduce repeated manual conversion work while keeping the final engineering review with the user.
Frequently asked questions
Does the intelligence diagnose undercharge or overcharge?
No. It can recognize explicit SH/SC deviation patterns against your entered reference tolerances, but those patterns can have multiple causes. The output recommends checks and an Issue Finder starting workflow; it does not prove charge state.
Why are all tolerances blank?
Because acceptable deviations depend on the equipment, application, operating context and commissioning/OEM basis. HVACR Studio does not insert universal refrigeration limits into a design-vs-field diagnosis.
What is the difference between a correlated pattern and a single-criterion signal?
A correlated pattern means multiple independently entered criteria moved in a known investigation direction at the same snapshot. It is stronger structured evidence than one metric, but it is still not a verified root cause or probability.
Why compare measured Q/input with theoretical COP at all if the boundaries differ?
Only when you explicitly provide an allowed shortfall. The comparison is a screening gap that can prompt review of capacity measurement, electrical boundary, OEM map performance, pressure drop and real-system effects. It is never used to infer compressor isentropic efficiency.
