Carrier HAP - Air Flow rates

[nevinjohn]

Hi,

For a heat load estimated with HAP, the fresh air requirment was 35lps, and HAP ouput shows that the supply air as 139L/s. Now my question is whether the AHU fan should be sized for 139L/s or the considering both fresh air and supply air, which is 35 + 139 Lps.

Hello Nevinjohn

The Air System Sizing Summary reports the total supply fan airflow rate of 139 L/s which includes the 35L/s of Outdoor Ventilation Air.
Note the Supply Fan Sizing Data section lists the 139 L/s as the total supply air volume.
I trust this helps.
