This tool is based on the CoolProp thermodynamic library and computes thermophysical properties—such as density, specific enthalpy, specific entropy, dynamic viscosity, thermal conductivity, specific heat at constant pressure, and compressibility factor—for common refrigerants at given temperature and pressure. All calculations run entirely in your local browser: secure and instant.
It supports mainstream refrigerants such as R134a, R410A, R32, R22, R404A, R407C, R290, R600a, R744 (CO₂), R717 (ammonia), R1234yf, and provides two calculation modes: “Known T & P” and “Saturated state”.
Usage Tips
- Input units: temperature °C, pressure bar.
- If the given state falls within the two-phase region (inside the saturation line), switch to the “Saturated state” mode and enter temperature or pressure.
- Results are for reference only. For critical conditions, please verify against REFPROP or an authoritative property handbook.
