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
