Refers to:
■ At fresh air temperature 28 °C: room air 22 °C, extract air 24 °C / 50 % rel. humidity
■ At fresh air temperature 32 °C: room air 26 °C, extract air 28 °C / 50 % rel. humidity

Note
The output for coverage of transmission (Q
TG
) allows for the ventilation
cooling requirement (Q
V
) and the output of the energy recovery (Q
ER
) under
the respective air conditions. It is calculated as follows:
