Abstract
“At the present time, moist air properties are well known at pressures near 1 atm, temperatures up to 200⁰ C, and humidity ratios from 0 to 0.09 kgw/kgda.
The goal of this research is to extend the current envelope of pressure, temperature, and humidity ratio and calculate more accurate psychrometric data for pressures up to 5 MPa, temperatures from 0 to 320⁰ C, and humidity ratios from 0 to 1.0 kgw/kgda.
In this research, a thorough literature search of the thermodynamic properties of moist air is conducted. The psychrometric data found are tabulated and compared. Based on the virial equation of state, moist air is assumed to be a real gas. The virial coefficients and cross-virial coefficients and their derivatives are used to calculate accurate psychrometric data in targeted psychrometric envelope. Psychrometric tables for pressures up to 5.0 MPa and temperatures from 0⁰ C to saturation temperature are developed in American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) format. Also, psychrometric charts for pressures up to 5.0 MPa, temperatures from 200 to 320⁰ C, and humidity ratios from 0 to 1.0 kgw/kgda are plotted in ASHRAE format.
This research incorporates the latest ASME data for saturation pressure, saturation temperature, enthalpy and entropy of both liquid water and water vapor, as well as isothermal compressibility of saturated liquid water. The equations for dry air properties, for water vapor properties, and for virial coefficients are determined by fitting the newest data given by the National Institute of Standards and Technology (NIST).”--Abstract, page iii.
