PsychroLib is a software library to enable the calculation of psychrometric properties of moist and dry air. Versions of PsychroLib are available for Python, C, C#, Fortran, R, JavaScript, Microsoft Excel Visual Basic for Applications (VBA). PsychroLib works in both metric (SI) and imperial (IP) systems of units. For a general overview and a list of currently available functions, please see the overview page.
Please see the Python API documentation for the common API across all the supported language implementations. In Python, array support and improved runtime performance can be optionally enabled by installing Numba. In R (1) constants, like ZERO_FAHRENHEIT_AS_RANKINE are not exported (i.e. not directly accessible to users), (2) functions accept a vector, not a scalar (3) bulk calculations, like CalcPsychrometricsFromRelHum return a list.
Examples on how to use PsychroLib in all the supported languages are described in this guide.
- Python: from the Python Package Index (PyPI). Numba can be optionally installed to enable array support and faster runtime performance.
- C# (.NET): from the NuGet package manager or clone the repository, and bundle according to your requirements.
- C, Fortran and JavaScript: clone the repository, and bundle according to your requirements.
- VBA/Excel: download the ready-made spreadsheets from the release tab.
- R: from the Comprehensive R Archive Network (CRAN).
