Thermoprops

Open Thermoprops → luisbedoia.github.io/thermoprops

Free calculator for thermodynamic properties of fluids and refrigerants. It runs entirely in the browser, on CoolProp compiled to WebAssembly.

Features

• 30 fluids and refrigerants: water, air, ammonia, CO₂, nitrogen, R134a, R410A, R32, R1234yf, propane…
• Fix any two independent properties (p, T, ρ, h, s, u, x) and get the full state, transport properties included.
• p–h, T–s, h–s, p–v, T–v and p–T diagrams, with the saturation dome, isolines and your states plotted together.
• °C, K or imperial units.
• Shareable links: fluid, units and states are stored in the URL.
• Works on phones, offline once loaded, and can be installed as an app.

Development

Properties come from @luisbedoia/coolprop-rs-wasm, published on GitHub Packages: installing it needs a token with read:packages in NPM_TOKEN (.npmrc reads it).

NPM_TOKEN=<token> npm ci
npm run dev       # development server
npm test          # unit tests
npm run build     # type check and production build

Pushing a v* tag deploys to GitHub Pages.
