Version 1.26

AirConditioning Library 1.26 is part of Modelon's 2023.2 release. New versions of Modelon's libraries are sold and distributed directly from Modelon, as well as approved resellers.

Version 1.26 contains the changes described below.

Build 1 (2023-06-21)

Major changes
  • ThermoFluidPro has been moved into AirConditioning and is no longer a separate library. This change should be covered automatically by conversion scripts. If conversion fails, it is possible to import Thermofluid using import AirConditioning.ThermoFluidPro; at top level of your own package.
New features
  • A NonIdeal sensors package has been added which enables the optional addition of dynamics, failure and analog-to-digital conversion effects to sensor outputs. This is done by adding NonIdeal block to the outputs produced by existing sensors in AirConditioning.ControllersAndSensors. These sensors can provide the same outputs as the existing ideal sensors by setting the parameter ideal=true. An example experiment showing the these effects using the non-ideal CoolantTemperatureSensor has also been added.
  • A new method to automatically sum up refrigerant volumes and masses has been introduced as AggregateTwoPhaseProperties. It uses inner/outer and an instance will be added automatically.
  • Mass conservation with density as additional state (pdh-states) has been improved regarding accuracy as well robustness.
  • Improved compliance with Modelica Language Specification.
Bug fixes
  • Fixed an issue where the secondary side cross section area was not consistently calculated in the plate heat exchangers located in AirConditioning.Heating.HeatExchangers.
  • Improved initialization of AirConditioning.AirHandling.AirHeater, by adding an init record instead of hardcoded enthalpy start value.
  • Fixed the units in specific heat capacity of air media.
