Pipe Sizing - Hevacomp

Why does the pressure drop (n/m2) in pipe sizing appear excessive but velocities are acceptable?

Can I set the maximum pressure drop per length in cws?

Hybrid Ventilation

Has anyone had any experience with hybrid ventilation units such as breathing buildings or monodraught?

If so how have you gone about your ventilation rates and inputting them as you can't guarantee a fixed supply air temperature as they have no heat recovery and are purely mixing (a glorified window essentially).

Air Change rates

George Henderson — Tue, 06 Nov 2018 15:07:06 GMT

Hi,

In the CAD input within thermal design within the a/c rate this is where we are inputting the infiltration rate of the building.

When it comes to the heatloss section where we are selecting the fixed air supply temperature and then inputting the air change rate here it does this globally. Is there a way to do this individually for each room as the air change rates are not the same for all rooms?
