An interactive and intelligent psychrometric chart program for HVAC engineers. It provides the most accurate and reliable data based on Hyland and Wexler's reports published by ASHRAE, which treat air and vapor as real gases, rather than ideal gases.
The only psychrometric charting program that can plot the psychrometric property lines on any combination of X & Y axis parameters. At least 60+ types of charts, in addition to the Psychrometric chart and Mollier diagram can be drawn.
A convenient, precise and powerful tool for HVAC&R engineers. This psychrometric chart is perfectly consistent with all ASHRAE charts of No.1~7(SI Units) and No.1~5(IP Units). Full functional trial, free upgrade.
