Ambience
Created Thursday 03 September 2020
This model provides a boundary condition heat flow of the wall to ambient.
1. Purpose of Model
This model can be used to set up heat loss to ambient.
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [1], this model refers to the level of detail L1 because the system is modeled without the use of balance equations.
2.2 Physical Effects Considered
- set values for ambient temperature, heat transfer coefficient at ambience surface and heat transfer area
2.3 Level of Insight
No different levels of detail are available.
3. Limits of Validity
4. Interfaces
4.1 Physical Connectors
- Heat connectors combined for:
- Temperature in the connection port [K].
- Heat flow rate [Watt]. 1-dimensional heat flow between components at the connection port.
4.2 Summaries
4.3 Inputs
- Real Input value for:
- Ambient temperature [K].
5. Nomenclature
6. Governing Equations
This model calculates heat flow to/from environment.
