Heat Pump alféa extensa duo

1 Description of the unit

1.1 Package

• 1 package: outdoor unit.

• 1 package: hydraulic unit and outdoor sensor.

1.2 Denitions

- Split: The heat pump consists of two elements

(an outdoor unit for outdoor and a hydraulic unit for

inside the dwelling).

- Air/water: The surrounding air is the energy source.

This energy is transmitted to the water in the heating

circuit by the heat pump.

- Inverter: the fan and compressor speeds are

modulated according to the heating requirements.

This technology enables you to save on energy and

operate on a single-phase power supply, whatever the

heat pump's output, by avoiding heavy intensities on

start-up.

- COP (coefcient of performance): this is the relationship

between the energy transmitted to the heating circuit

and electrical energy consumed.

1.5 Operating principle

The heat pump transmits the energy contained in the

surrounding air into the dwelling to be heated.

The heat pump consists of four main elements, in which

a refrigerant uid (R410A) circulates.

- In the evaporator (ref. 13, gure 6, page 9) :

The energy is taken from the surrounding air and is

transmitted to the refrigerant. Because it has a low

boiling point, it changes from the liquid state to the

vapour state, even in cold weather (down to -15 °C

outdoor temperature).

- In the compressor (ref. 10, gure 6, page 9) :

The vaporised refrigerant brought to high pressure

and takes on more calories.

- In the condenser (ref. 15, gure 7) :

The energy in the refrigerant is transmitted to the

heating circuit. The refrigerant returns to liquid state.

- In the expansion valve (ref. 9, gure 6, page 9) :

The liqueed refrigerant is brought back to low pressure

and returns to its initial temperature and pressure.

The heat pump is equipped with a controller, which

controls the room temperature based on the outdoor

temperature measurement and governed by the

temperature control. The room thermostat (option)

provides a corrective action for the temperature control.

The hydraulic unit can be optionally tted with an

electrical back-up system or boiler connection which

starts up in order to provide addtional heating during the

coldest periods.

• Regulation functions

- The heating circuit's initial temperature is controlled by

the temperature control.

- The power of the outdoor unit is modulated according

to ow heating temperature via the "inverter"

compressor.

- Control of the electrical back-up heating (option).

- The daily timer program enables you to dene

the periods for comfortable or reduced ambient

temperature.

- Summer/winter mode switchover is automatic.

- Control of the supplementary boiler* (option / the

electrical back-ups are deactivated).

- The room thermostat (option)*: provides a corrective

action for the temperature control.

- Control of a second heating circuit*.

- Domestic hot water: Heating time programme, control

of the operation of the DHW circulation pump.

- Managing the cooling*.

- Control of swimming pool heating*.

* If the heat pump is equipped with optional equipment and the

associated kits.

• Protection functions

- Anti-legionella cycle for domestic hot water.

- Anti-corrosion protection with titanium anode (ACI).

- Frost protection, DHW,...
