Book Description:
Understanding Psychrometrics serves as a lifetime reference manual and the basic refresher course for those who use psychrometrics on a recurring basis and provides a four- to six-hour psychrometrics learning module to students; air-conditioning designers; agricultural, food process, and industrial process engineers; meteorologists; and others.

 New in the Third Edition
  •  Revised chapters for wet-bulb temperature and relative humidity and a revised Appendix V that includes a summary of ASHRAE Research Project RP-1485.
  • New constants for the universal gas constant based on CODATA and a revised molar mass of dry air to account for the increase of CO2 in Earth's atmosphere.
  • New IAPWS models for the calculation of water properties above and below freezing.
  • New tables based on the ASHRAE RP-1485 real moist-air numerical model using the ASHRAE LibHuAirProp add-ins for Excel, MATLAB, Mathcad, and EES. Features: Includes Access to Bonus Materials and Sample Software: PDF files of 13 ultra-high-pressure and 12 existing ASHRAE psychrometric charts plus three new 0ºC to 400ºC charts. A limited demonstration version of the ASHRAE LibHuAirProp add-in that allows users to duplicate portions of the real moist-air psychrometric tables in the ASHRAE Handbook Fundamentals for both standard sea level atmospheric pressure and pressures from 5 to 10,000 kPa. The hw.exe program from the second edition included enabling users to compare the 2009 ASHRAE numerical model real moist-air psychrometric properties with the 1983 ASHRAE-Hyland-Wexler properties. The benefit to the Customer: Multipurpose, go-to resource for students
