Operating principle

The appliances in the 1.6 kW range produce
domestic hot water mainly 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 (using
heat exchangers).
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
capillary tube 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
an overheated vapour
condensing at a constant pressure and dropping
in temperature;
IV-I: the refrigerant liquid passes through the
capillary tube, 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.
