This psychometric chart is precise and powerful tool for HVAC&R engineers because it uses ASHRAE equations at normal temperature and pressure region as well as it is perfectly consistent with all ASHRAE charts of No.1~7(SI Units) and No.1~5(IP Units). It supports both Metric (SI) and English (IP) units. You can save and load data function for each data input grid as well as all input data can be saved for loading next time. Its major features are it is using IAPWS-IF97 equation for water/vapor properties calculating, and treat moist air as real gas for high precision as well as Dry bulb temperature and humidity ratio axis range can be changed easily; you can Draw protractor for enthalpy-humidity and sensible-total heat ratio; it supports Mouse point catch, snap and calculation, output point information and many air properties as well as it also supports Normal and eastern(China) style; it has user friendly interface for processing and mixing point calculating; you can calculate recycle once and twice, and many more.
