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 fabric cooling losses (Q
TG
) allows for the ventila-
tion cooling requirement (Q
V
) and the output of the energy recovery (QER)
under the respective air conditions. It is calculated as follows:

= Q
