# .AixLib.ThermalZones.HighOrder.Components.DryAir.InfiltrationRate_DIN12831

Heat flow caused by infiltration after european standard DIN EN 12831

## Information

Overview

The InfiltrationRate model describes heat and mass transport by infiltration.

Concept

Air exchange coefficients at 50 Pa pressure difference between ambience and room air:

coefficients
#### Dwelling type | #### highly air tight | #### medium air tight | #### low air tight
one-family dwelling | < 4 | 4 - 10 | > 10
multi-family dwelling/other | < 2 | 2 - 5 | > 5

Reference values for air shielding value e:

Reference
| #### heated room without facade with openings exposed to wind | #### heated room with one facade with openings exposed to wind | #### heated room with more than one facade with openings exposed to wind
no shielding | 0 | 0.03 | 0.05
moderate shielding | 0 | 0.02 | 0.03
well shielded | 0 | 0.01 | 0.02

Reference values for height correction value ε:

Reference
#### Height of room | ε
0 - 10 m | 1
10 - 30 m | 1.2
> 30 m | 1.5
