Operating principle

7612035 - v02 - 12062014
The ALEZIO V220 EVOLUTION heat pump is composed of:
A reversible outside module for energy production in Hot or Cold mode.
An inside module with a control panel to handle the thermal exchange
between the R410A fluid and the hydraulic circuit.
Both units are connected by means of refrigeration and electrical
connections. The inside module handles domestic hot water production.
The system offers the following advantages:
The heating circuit is housed in the insulated volume within the home.
Thanks to the DC inverter, the heat pump modulates its output to adapt
to the needs of the home.
The control panel uses the outside sensor to adjust the temperature of
the heating circuit according to the outside temperature.
The steel domestic hot water tank is lined with food quality standard
enamel vitrified at 850°C, which protects the tank from corrosion.
The heat exchanger in the domestic hot water tank is a coil welded
inside the tank, made of smooth piping. Its external surface, which
comes into contact with drinking water, is enamelled.
The appliance is insulated by Chlorofluorocarbon-free polyurethane
foam, which helps to reduce heat losses to a minimum.
The outside casing is made of painted steel sheeting.
The tank is protected against corrosion by a magnesium anode.

4.2.1 Hybrid operating mode

Note
The hybrid operating mode is only available for appliances with
hydraulic back-up.
The appliance offers a choice between several hybrid operating modes.
The modes available offer either optimised energy consumption according
to energy cost, or optimised energy consumption according to primary
energy consumption. Both hybrid operating modes are available via the
parameter .
In optimised primary energy consumption mode, the control system
chooses the generator that consumes the least primary energy.
In optimised energy cost mode, the control system chooses the
cheapest generator according to the coefficient of performance of the
heat pump and according to energy cost.
