High efficiency air handling unit (AHU)
Reference: B.6.1
LEME Mitigation
Reducing electricity consumption by replacing existing AHU
HVAC for large spaces
At least IE2 class efficiency motor equipped withVSD (variable speed drive)
EN 814-2 (E 36-104-2)
Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)
Medium/long term
Fans electricity consumption is reduced by high efficiency IE2 motors driven with VSD . In case of a heat recovery handling unit, extracted fresh air cross an heat exchanger to refresh new air and reduce electricity consumption for air conditioning
