HumanComfort models the dynamic, thermal behaviour of buildings, vehicles, ship and aircraft cabins. Additionally, the thermal comfort of persons and passengers can be determined. The product contains the modular description of all physical heat transfer processes (ready-to-use).
Energy systems are optimized in accordance with economic criteria. From the view of a user of an air conditioning/heating system the thermal comfort is very often of more importance. How the thermal comfort changes with personal and thermal factors was examined in several studies and put into classification numbers. Standardized calculation methods of these numbers were developed and allow a detailed analysis of the human comfort.
The HumanComfort Modelica library contains models which allow a mathematical evaluation of the thermal comfort. Its modular structure and the standardized interfaces make a flexible implementation in other Modelica libraries possible. Every HumanComfort module can be exchanged. Thus, the user can combine his own building model with the HumanComfort Library and use e.g. the HumanComfort weather and comfort model. Additionally, individual room or cabin models can be built with the components from the HumanComfort Library. See in a video tutorial how to create a thermal building model in less than one hour.
Simultaneous dynamic simulation of conditioned zones and air conditioning
Analysis of interactions of air conditioning and dynamic zones effects
The models of the HumanComfort Library can be used to optimize the development of air conditioning systems of vehicles and buildings.
The HumanComfort Library allows the simultaneous dynamic simulation of conditioned zones and air conditioning contrary to the previous state of the art (see info box below). The analysis of interactions of air conditioning and dynamic zones effects is possible.
Analysis how the failure of the air conditioning affects the human comfort can be made by simultaneously simulating the building and the air conditioning. Moreover, the performance decrease due to environmental changes and its effects on the comfort can be estimated with the HumanComfort Library.
Thus, the HumanComfort Library supports the optimal control of an air conditioning system (e.g. heat pumps, solar supported air conditioning, etc.).
The Zone Package contains models to develop mobile or stationary applications. Mobile applications will be built with models e.g. for aircraft or vehicle cabins. All models can individually be built and fitted. The Modelica Code is open and not encrypted.
To use the Zone package for stationary applications a building simulation is provided within the HumanComfort Modelica Library. Every zone can be combined with a weather and a HumanComfort module (see figure).
Multi room models are built of single room models which are connect with Modelica Fluid or thermal connectors (see figure).
The zone models account for the following physical phenomena:
- Solar irradiation
- Heat transfer through walls and windows
- Heat conduction
- Heat transfer caused by air exchange
- Thermal activation of wall layers
All zone models can be parameterized with different material properties and the user behaviour can be simulated (heat, humidity and CO2 sources).
The air zones can be simulated with moist or dry air and in addition CO2 can be regarded.
The zone models are supplemented by detailed examples of buildings, vehicles and aircrafts.
