What it can do

Returns a full state point (temperature, pressure, density, enthalpy, entropy, quality, transport properties, phase) from any two independent inputs, by calling the CoolProp library.
Gives saturated liquid and vapour states with latent heat and temperature glide, which suits refrigerant blends such as R407C.
Reports fluid data such as critical and triple points, molar mass, limits, GWP and ODP, and moist-air properties for HVAC work.

Limitations

All inputs and outputs are SI (K, Pa absolute, J/kg), so the agent must convert from °C and bar.
The README's setup steps and config paths are for Windows PowerShell and the author's own folders; adjust them for your machine.
No licence file, and the repository is a small single-author project.
