Operating curves
A: Pressure loss supplement with ePM1 55% filter (F7)  
B: Pressure loss supplement for heating/cooling coil

 

To calculate capacity data use the product selection tools Quickselect and EXselect.

Total energy consumption is divided equally between the extraction and supply air fans.

Absorbed power with VEX: P1(W) = SFP (J/m3) x qv (m3/s).


Temperature efficiency

VEX300C temperaturvirkningsgrad

stiplet streg
Efficiency with condensation:
Extract air = 20°C/55 RH
Outdoor air  = -10°C/50 RH
Balance between supply air/extract air = 1,0
kort-lang-stiplet-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
fed 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

Calculation

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


t2,1 = Temperature of outdoor air (fresh air)
t2,2 = Temperature of supply air
t1,1 = Temperature of extract air
