Understanding psychrometrics

Description

This book serves as a lifetime reference manual and 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 EditionRevised 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®.Content: Front Matter • Preface • Preface to the Third Edition • Table of Contents •Part I.
