Description Details Pakcage options Note Author(s) See Also Examples

Contains functions for calculating thermodynamic properties of gas-vapor mixtures and standard atmosphere suitable for most engineering, physical and meteorological applications.

Most of the functions are an implementation of the formulae found in the 2017 ASHRAE Handbook - Fundamentals, in both International System (SI), and Imperial (IP) units. Please refer to the information included in each function for their respective reference.

psychroLib is a port of the psychrolib library for R.

psychrolib.units The default unit system. Should be either be "SI" or "IP".

We have made every effort to ensure that the code is adequate, however, we make no representation with respect to its accuracy. Use at your own risk. Should you notice an error, or if you have a suggestion, please notify us through GitHub at https://github.com/psychrometrics/psychrolib/issues.

Hongyuan Jia and Jason Banfelder for R implementation.
D. Thevenard and D. Meyer for the core library implementations.
