“If I build a better one, would you use it?”

I asked my teacher this after an app for calculating refrigerant leak-check intervals couldn’t properly handle blends and gave incorrect results.

I started studying refrigeration this autumn. And here we are again. Learning something new and building a tool for it at the same time. Or several.

That question became PhaseKit. It started with one calculator, but other things soon found their way in. Refrigerant data I needed to check. A formula I couldn’t remember. A diagram symbol I didn’t recognise. There are now tools for keeping site and equipment details and putting reports together, too.

Apparently, building things has become one of the ways I learn. Trying to make a calculation understandable to someone else tends to expose the gaps in your own understanding. Do I actually get this? Where does that value come from? When does this formula apply?
I wanted those workings to stay visible. The formulas, the sources, and the gaps in the data. The code is open source under the MIT licence, so other people can look through it, change it or build something of their own from it.

PhaseKit is now there for anyone to try. It runs in a browser, including on your phone, and works offline after the first load. No account needed.

I’m still new to refrigeration, so I’d be interested to hear what someone else makes of it. Something useful, something awkward, or something I’ve misunderstood. All useful things to learn from.
