at a known altitude (or atmospheric pressure). The properties are determined using the ideal gas law for
the behavior of air. Once the properties are determined, the point is indicated on the Psychrometric chart.
Process lines can be connected between any two know points, this will provide the user with the differences
in moving from one point to the next. Additionally, this program will allow the user to perform some basic
HVAC calculations that depend on psychrometrics.
applications. In addition, the porgram calculates the results of the four most common types of heating and
cooling psychrometrics processes.
