Temperature efficiency

Temperature efficiency, CX3030

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 EXselectPRO calculation software.

Curve-temperature-efficiency-CX3030
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

dashed line

Efficiency with condensation:
Extract air = 20 °C/55 % RH
Outdoor air = -10 °C/50 % RH
Balance between supply air/extract air = 1.0

short-long-broken-line

Efficiency without condensation with imbalance:
Extract air = 25 °C/30 % RH
Outdoor air = 5 °C/50 % RH
Balance between supply air/extract air = 0.8
bold line
Efficiency without condensation in acc. with EN308:
Extract air = 25 °C/30 % RH
Outdoor air = 5 °C/50 % RH
Balance between supply air/extract air = 1.0

Calculation 

The temperature efficiency of the CX air handling units are shown at different airflow ratios, calculated as:
formula-supply-air-Extract-air
Formula-temperature-efficiency
t2.1 = Temperature of outdoor air (fresh air)
t2.2 = Temperature of supply air
t1.1 = Temperature of extract air
