Operating principle

The appliances in this range produce domestic hot
water using heat-pump technology. A heat pump
transfers thermal energy from a source at a lower
temperature to a source at a higher temperature,
and vice versa (heat exchanger).
The appliance uses a hydraulic circuit composed
of a compressor, an evaporator, a capacitor and
a thermal expansion valve. A refrigerant fluid/gas
flows in the circuit (see section 4.6).
The compressor creates a difference in pressure
inside the circuit, which creates a thermodynamic
cycle. The compressor aspirates the refrigerant
fluid through an evaporator, where it evaporates
at low pressure absorbing heat, compresses it and
forces it towards the capacitor, where the fluid
condenses at high
absorbed heat. The fluid then passes through a
thermal expansion valve and, decreasing in
pressure and temperature, starts to vaporise and
enters the evaporator again, restarting the cycle.

The appliance operating
(Fig. 1):
I-II: the refrigerant
compressor runs inside the evaporator and, while
evaporating, absorbs
provided by the air.
At the same time, the air in the space is aspirated
by the appliance, thanks to the fan. As it passes on
the finned battery of the evaporator, the air
releases its heat;
II-III: the refrigerant
compressor and there is an increase in pressure
which raises the temperature, turning the gas into
overheated vapour;
III-IV: in the capacitor, the refrigerant gas releases
its heat in the water in the tank (boiler). This
exchange process transforms the refrigerant from
pressure, releasing the

IV-I: the refrigerant liquid passes through the
thermal expansion valve, quickly dropping both in
pressure and temperature. It partially vaporises,
returning to the initial pressure and temperature
conditions. The thermodynamic cycle can now
start again.
