    Nov 10, 2015 · Psychrometric charts can be pretty tricky to interpret. Just taking a look at it, you may already be confused. With so many lines and axes, you can get lost trying to follow the chart and find out which line represents which axis.

  • Sww ishtar strainThe use of psychrometric charts requires skill by the user, which restricts their use. Thus, mathematical modeling of the equations and subsequent computer simulation of psychrometric charts significantly simplify their use, eliminating reading errors. ,point can thus easily be found by using equations 2 and 13 (see equations 2a and 13a below). Since water will condense on surfaces with sub-td tempera-tures, td is an important factor in determining safe minimum indoor air temperatures. Although not a measure of humidity, specific enthalpy (h) in kJ/kg is often given in psychrometric charts.
