Temperature efficiency

Temperature efficiency, VEX170H

Temperature efficiency, VEX170
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 air handling units are 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.
