Based on ASHRAE RP-1485, Thermodynamic Properties of Real Moist Air, Fog, Ice Fog, Dry Air, Steam, Water, and Ice (March 12, 2009), the ASHRAE Library of Humid Air Psychrometric and Transport Property (LibHuAirProp) Functions (FluidDYM for DYMOLA), I-P and SI units, 32-bit version includes 60 property functions. Ready for application, they work within LabVIEW. Key features of the library include:

• It works with “Real” versus “Ideal” Air
• It updates the ASHRAE Hyland-Wexler and Nelson-Sauer Models
• Properties of liquid and ice fog can also be calculated
• All latest IAPWS standards and NIST reference equations are used
• It offers a wide range of validity
  • Pressure: 0.01 < p < 10,000 kPa
  • Temperature: -143.15 < t < 350 °C
  • Humidity Ratio: 0 < W < 10 kgw/kga
