FUNCTIONALITY

Moist air properties:

  • atmospheric pressure based on height above sea level,
  • temperature change based on height above sea level,
  • water vapour saturation pressure,
  • dew point temperature and wet bulb temperature,
  • air relative humidity,
  • humidity ratio and maximum humidity ratio,
  • kinematic and dynamic viscosity,
  • thermal conductivity,
  • specific enthalpy of humid air with water mist and ice mist components,
  • specific heat,
  • density,
  • thermal diffusivity,
  • Prandtl number.

Liquid water properties:

  • specific heat,
  • density,
  • specific enthalpy.

Physics of flow:

  • mass flow,
  • volumetric flow,
  • mass flow of dry air component,
  • volumetric flow of dry air component,
  • based on flow type specified during instance creation, other flows will be recalculated accordingly for specified
    Fluid properties,

Air heating:

  • heating process for input heat,
  • heating process for target outlet air temperature,
  • heating process for target outlet air relative humidity,

Air cooling:

  • dry cooling process for input heat,
  • dry cooling process for target outlet air temperature,
  • real cooling process with condensate discharge process for input heat,
  • real cooling process with condensate discharge process for target outlet temperature,
  • real cooling process with condensate discharge process for target outlet relative humidity,

Air stream mixing:

  • simple mixing of two flows with humidity content,
  • mixing of multiple flows with humidity content,
  • mixing algorithm which will try to adjust inlet and recirculation flow accordingly, to meet target output dry air mass
    flow and target outlet temperature.
