KEY
(1) FLA = Max. Current absorbed at full load
(2) LRA = Peak current at full load
(3) = With electronic thermstatic valve
the minimum step is 25%
EEEC = EUROVENT Energy Efficiency Class
Sound Power
Aermec determines the value of sound power
on the basis of measurements performed in
compliance with regulation 9614, in respect with
that requested by Eurovent certification.

There is a growing awareness in Europe as well
15 °C that attention needs to be paid to the electricity
2 °C consumed by air conditioning machines. For
0% many years now in the United States talk has
not just been about efficiency in the plan con-
ditions, but an assessment index is used that
takes account of the marginal operation of the
unit under plan conditions and the greater use
with partial loads with external air that is less
than that planned and in conditions of compres-
sor capacity control. In Europe the proposed

EECCAC (Energy Efficiency and Certification of
Central Air Conditioner) has been adopted, the
ESEER (European Seasonal Energy Efficiency
Ratio), that has the purpose of being able to
compare the chillers with each other.
After estimating the total energy required
by the system during summer management
(kW/h), the seasonal electrical energy con-
sumption can be deduced with this
formula:
Input energy = Required energy
Efficiency index
The actual energy calculation can be obtained,
more accurately, by considering:
1. The load profile with external temperature
2. The climatic profile
3. The total number of hours
With this data, every consultant or designer will
be able to his or her evaluations.
