Innovations in flixo 8

  • Support of the new computational method of EN ISO 10077-2. With the revision of the standard 10077-2 of 2017 an additional computational method for heat transport in air cavities has been introduced:
    • Slightly ventilated cavities are modeled as boundary conditions (using temperature and heat transmission resistance).
    • The radiation exchange in unventilated cavities is correctly modeled physically (radiosity method).
    • The heat transport by means of convection/radiation in unventilated air cavities is based on the same equations as with the existing method. However, it uses the mean direction of heat flow within the air cavity in contrast to the principal direction of heat flow (horizontal or vertical).
