Dear forum members,
Airflow measurements were conducted on our controlled residential ventilation system "Enervent Pingvin" after we reported that the indoor air did not feel fresh and that the incoming airflow seemed low.
The results are attached.
The measured supply air volume is 35 m³/h (21 ft³/min) lower than the planned volume: 140 m³/h (82 ft³/min) instead of 175 m³/h (103 ft³/min). According to the ventilation unit’s datasheet, it should deliver an airflow of 190 m³/h (112 ft³/min) at 60% setting. The measurements show it produces 50 m³/h (29 ft³/min) less.
I would appreciate your opinion on these measured airflow values.
Thank you in advance.
Kind regards,
GerdS

Hello,
Also, it is somewhat unusual that the measured values are quite even and "round" numbers. Overall, it seems that no duct network calculation was carried out in advance!
How were the actual values measured?
Best regards
