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
Outdoor air (fresh air) = 5 ºC

Temperature efficiency is shown in accordance with EN308 at dry heat recovery and is increased with condensation.
