Table 13. Supply and extract air volumes - description of the diagram
| Code | Description |
|---|---|
| A | Pressure loss in ducts. Total pressure (Pa) |
| B | Volume flow rate (dm3/s) |
| Continuous line (—) | Extract air |
| Broken line (┄) | Supply air |
|
P |
Extract air fan |
|
T |
Supply air fan |
|
SFP |
SFP rate (Specific Fan Power) recommended value <1.8 (kW m3/s). When a lower total pressure is used, also the SFP of the speed is lowered. |
