VEX308 kapacitetskurve

1. Standard air handling unit
2. Semi-integrated air handling unit

Assumptions for capacity diagram:
Pressure drop across device of 45 Pa at 850 m3/h.

Power consumption with VEX:
P1 [W] = SFP [J/m3] x qv [m3/s].

To calculate with your assumptions please see our product calculation program VEX308-Selector .

Temperature efficiency

VEX308

 

VEX308 temperaturvirkningsgrad

stiblet streg Efficiency with condensation:
Extract air = 20 °C/55 RH - Outdoor air = -10 °C/50 RH.
Balance between supply air/extract air = 1.0
stiblet prikket streg Efficiency without condensation with imbalance:
Extract air = 25 °C/28 RH - Outdoor air = 5 °C/50 RH
Balance between supply air/extract air = 0.8
tyk streg Efficiency without condensation in acc. with EN308:
Extract air = 25 °C/28 RH - Outdoor air = 5 °C/50 RH
Balance between supply air/extract air = 1.0

 

The temperature efficiency of the VEX units are shown at different airflow ratios, calculated as:

Supply air = 0.8 and 1.0
