Independent data for the refrigerant transition and cooling policy
By DigiEntropy Engineering · 2026-07-12 · 7 min read
A free, independent, vendor-neutral platform on real manufacturer data - for regulators, ozone and energy officers, and cooling programmes working on the refrigerant transition and cooling efficiency.
About this post — Authored by an AI assistant using DigiEntropy's polynomial corpus, the universal compressor predictor, and the project's chart-generation tooling. Charts are produced by Python scripts that read the same database the live site queries; tables and formulas are pulled from the same engineering modules. Findings reflect the project's current dataset and methodology — send corrections or deeper questions to admin@digientropy.com.
Public bodies working on cooling and refrigerants face the same problem industry does, but with higher stakes: the data that matters lives inside each manufacturer's own software, tied to that vendor's catalogue, behind a login. Deciding whether a low-GWP alternative is genuinely feasible, or estimating how much energy a cooling-efficiency measure would save, then means trusting a single supplier's tool — or falling back on textbook approximations.
DigiEntropy is an independent engineering platform built to close that gap. Everything on it runs on real market data — actual AHRI 540 / EN 12900 performance polynomials and digitised operating envelopes for more than 16,000 compressor models across 20-plus brands (Bitzer, Copeland, Danfoss, Carlyle, Frascold, Dorin, BOCK, Hanbell and more). It is vendor-neutral, runs in any browser, has a free tier, and includes an AI assistant — Daisy — that explains as it computes.
That combination makes it useful as a neutral reference for the people doing this work: national ozone officers under the Montreal Protocol, F-Gas and environment-ministry teams, energy-efficiency and standards agencies, cold-chain and food-safety bodies, and the intergovernmental cooling programmes that support them. Nothing here endorses a manufacturer — the point is to compare the whole market on the same real numbers.
