Intry Verified receipt
Is the Intry Chiller Condenser Approach Temperature accurate?
The provenance receipt for the Intry Chiller Condenser Approach Temperature: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against, rebuilt from their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 28314 automated checks re-derive and source-check the numbers against the Trane and YORK operation manuals the approach definition was read from, and this site's PT tables before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- Trane CVHH-SVX001J-EN (October 2019), CVHH Water-Cooled CenTraVac Chillers With Tracer AdaptiView Control, Installation, Operation, and Maintenance: Recommended Maintenance, Condenser, page 110 · YORK Form 160.75-O1 (425), Issue Date 2025-04-24, Model YK Style G with R-134a, R-513A, or R-1234ze, Operations Guide: Operating log sheet (page 16) and Daily inspections (page 17) · This site's PT tables (the superheat and subcooling engine), for saturation from pressure · The effectiveness-NTU algebra, re-run by this site on 2026-09-08 (the derivation behind the illustration table) · Trane CTV-SVX05H-EN Figure 2, through the purge tool · Johnson Controls / YORK SI0389 (226), the YK R-134a to R-513A conversion bulletin. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any release, an automated check rebuilds the calculated figures from the locked engine that produces them and holds each one against the source it cites, so a number answers to its source and not merely to itself. As of the current build that suite holds 28314 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine behind the published numbers on this site. Runnable access is offered on the calculators exposed at the Intry MCP endpoint.
- Final say
- The chiller's manufacturer and its service literature have final say on what the machine's approach should be and when the tubes are cleaned; this tool compares only to the commissioning record you enter, scaled to the present load.
