Temperature efficiency

VEX140CF

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. 

VEX140CF temperature efficiency 
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
Extract air = 25 ºC / 30 % RH
Outdoor air (fresh air) = 5 ºC / 50 % RH

Temperature efficiency is stated in accordance with EN308 for dry heat recovery and is increased by condensation.
