Measurements made according to EN 13141-7.
Heating the supply air is energy consumption consumed when supply air is heated to +21°C degrees.
Warming of infiltrated air is energy consumption consumed when leakage air (outdoor air coming inside from cracks etc.) is heated to +21°C
The part of the annual energy that the unit recovers up to room temperature +21°C
The part of the annual energy that the unit recovers up to selected supply air temperature
Heat exchanger efficiency according to SFS-EN308
SFS-EN13141-7 (including fans)
