Summary

Python library to calculate psychrometric states of moist air.

Installation

Place either psySI.py or psyIP.py file in your working directory. If you are working with the international system of units (i.e. SI) then use psySI.py. If you are are working with imperial units (i.e. IP) then use psyIP.py.

Description

psypy is a python library that calculates psychrometric states of moist air using ASHRAE 2009 Fundamentals formulations. Atmospheric pressure, and two independent properties must be given to calculate all other state properties. The state properties include: dry bulb temperature (DBT), specific enthalpy (H), relative humidity (RH), specific volume (V), humidity ratio (W), and wet bulb temperature (WBT). Examples can be found in the examples.py file.
