CONDITIONS
The technical data is calculated as follows
Cooling mode
- Temperature water inlet
- Temperature of processed water
- Ambient air temperature
- ∆t
Heating mode
- Temperature of processed water 50 °C
- Ambient air temperature
- ∆t
Sound Power
Aermec determines the value of sound
power on the basis of measurements per-
formed in compliance with regulation 9614,
in respect with that requested by Eurovent
certification.
Sound Pressure
(1)
Sound pressure in free field on a reflective
surface (factor of directionality Q=2), at 10
metres from the external surface of the
unit, using the parallel expansion method
(box-method, ISO 3744)

There is a growing awareness in Europe

as well that attention needs to be paid

to the electricity consumed by air condi-
5°C
tioning machines. For many years now in
the United States talk has not just been
about efficiency in the plan conditions, but
b.s. 7 °C
an assessment index is used that takes
b.u. 6 °C
account of the marginal operation of the
5°C
unit under plan conditions and the greater
use with partial loads with external air that
is less than that planned and in conditions
of compressor capacity control. In Europe

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 manage-
ment (kW/h), the seasonal electrical ener-
gy consumption can be deduced with this
formula:
Input energy = Required energy
Efficiency index
The actual energy calculation can be obtai-
ned, more accurately, by considering:
1. The load profile with external tempera-
ture
2. The climatic profile
3. The total number of hours
