Temperature efficiency

Temperature efficiency, VEX170H

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

t_2,1	=	Temperature of outdoor air (fresh air)
t_2,2	=	Temperature of supply air
t_1,1	=	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.
