Independent data for the refrigerant transition and cooling policy

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. A neutral view of the whole market Before drilling into one decision, it helps to see the landscape. The Compressor Galaxy plots every model in the corpus on one interactive chart, filterable by refrigerant, capacity and brand — a fast way to see how much of the market already runs on each refrigerant, and which models survive each step of a phase-down schedule. The refrigerant transition, with real performance The core policy question under the Kigali Amendment and the EU F-Gas Regulation is whether the lower-GWP alternatives actually work in place of the high-GWP fluids being phased down. The F-Gas Retrofit tool answers it on real data: give it an incumbent compressor and refrigerant, and it ranks the replacement options by GWP, PFAS tier, capacity match and COP delta — not a lookup…
