Temperature efficiency, VEX330H1

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, EXselectPRO.

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

	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 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
