CoolProp.Plots.psy module

class CoolProp.Plots.psy.PsyCoolprop(**kwargs)

Bases: object

Psychrometric state using coolprop library

kwargs definition parameters:

P: Pressure, Pa z: altitude, m

tdp: dew-point temperature tdb: dry-bulb temperature twb: web-bulb temperature w: Humidity Ratio [kg water/kg dry air] HR: Relative humidity h: Mixture enthalpy v: Mixture specified volume

P: mandatory input for barometric pressure, z is an alternate pressure input it needs other two input parameters:

0 - tdb, w 1 - tdb, HR 2 - tdb, twb 3 - tdb, tdp 4 - tdp, HR 5 - tdp, twb 6 - twb, w
