Motor data (optimal operating point)
EC motor With motor controller
Power consumption 0.50 kW
Airflow 1,355 m3/h
Total pressure 733 Pa
RPM during optimal operating point 3,735

 

 Conditions:

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.

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

Temperature efficiency

VEX330H2

The temperature efficiency and, to a lesser extent, the SFP/SEL values for a specific air handling unit are closely connected to the heat exchanger itself and depend upon the manufacturer. As suppliers can change from time to time, small changes in the technical data can occur, which is why it is always recommended that you perform a calculation for the particular project using our calculation software, EXselect.

The curve is intended as a guideline, and it is recommended that a calculation be performed using the calculation software EXselect for the individual project.

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
