riduces consumptions and increases the value of your home.
Maximum seasonal efficiency
Unlike
traditional systems,
the ELFOFresh
2
active thermodynamic circuit
recovers the energy contained in the flow of exhaust
air, it
multiplies it using heat pump technology and then provides it to the served building with high efficiency.
Heating
The ELFOFresh
2
energy efficiency is very
high because the heat source, with which
such heat pump operates, is the exhaust air,
having favourable conditions.
During winter operation, for example, with
fresh air temperature –5°C and extracted air
at 20°C, the ELFOFresh
2
COP is higher than
5.5.
The heating capacity minimizes the fresh air
load, providing further power to maintain
the comfort conditions. The result for users
is a reduction up to 40% of the heat primary
energy consumption than a traditional
system.
Cooling
Besides recovering the exhaust air heat
that, unlike the traditional system also
takes place during summer operation, the
active recovery generates a quantity of
energy supplied to the building also during
summer. In this way, the active recovery
compensate the heat loss through walls and
roof of the building.
Therefore, ELFOFresh
2
is able to reduce the
30% of cooling primary energy versus a
traditional system with a passive recovery
and direct expansion system.
