LibHuAirProp Add-In Demo

This is a limited demonstration version of the ASHRAE Library of Psychrometric, Thermodynamic, and Transport Properties for Real Humid Air, Steam, Water, and Ice (LibHuAirProp) add-in.

The full version of LibHuAirProp can be purchased from the ASHRAE Bookstore.

This demo includes three examples that are selectable from the EES menu bar:

  • ASHRAE_HOF_MoistAirTable calculates Real Moist Air properties from 0°C to 80°C. You may optionally change the pressure or input different temperatures; e.g. 20°C to 25°C in 0.1°C increments
  • enhancement_factor calculates a table of water vapour pressure enhancement factors from -100°C to 350°C at pressures from 10 to 10,000 kPa. Users may change the temperatures. A plot window displays factors at four total pressures
  • LibHuAirProp_Statepoints_SI calculates 13 Real Moist Air Psychrometric properties when any three of the properties are entered in a Parametric Table row. It includes five sample rows and provides an additional five rows for your inputs. To Solve Runs 2-5: Select "Calculate" then "Solve Table" and then change the "Last Run Number" to 5.

HW.exe

In 2009, ASHRAE replaced the 1983 ASHRAE-Hyland-Wexler real-moist-air numerical model with the research project RP-1485 LibHuAirProp real moist air model. The hw.exe program allows users to generate a table of 1983 Hyland-Wexler psychrometric properties, which may then be compared with the 2009 ASHRAE real moist air numerical psychrometric model.

Installation Instructions

  1. Download the compressed file.
  2. Unpack the contents to your computer.
  3. To open the program, double click HW.exe.
