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
— These operating conditions are not permissible, because the maximum condensate quantity of 60 kg/h is exceeded.

Note
The output for coverage of fabric cooling losses (Q
TG
) allows for the ventilation cooling require-
ment (Q
V
) and the output of the energy recovery (Q
ER
) under the respective air conditions. It is
calculated as follows: Q
TG
= Q
