3.1. OPERATING PRINCIPLE
The SWP module produces domestic
hot water using established heat pump
technology. The operating principle is as
follows:
• The refrigerant fl uid changes state in
the evaporator, taking heat from the
low-temperature source (the outside
air).
• The compressor, which is the pulsing
heart of the system, raises the energy
level of the extracted heat: in fact,
the refrigerant fl uid, increasing in
pressure, reaches temperatures
which are capable of heating the
water in the accumulation tank.
• In the condenser, heat energy can
be transferred to the domestic water,
which reaches temperatures of up to
60°C. The accumulation tank (200,
300 litres) makes it possible to store
this heat for a long time, thanks to
its 50 mm polyurethane insulating
jacket.
• Finally, as it passes through the
expansion tank, the pressure and
temperature of the fl uid drops again,
and it can be used to "feed" more
"environmentally friendly" heat from
the air sucked. It is also possible to use
auxiliary sources, with supplementary
exchangers, by connecting them to
boilers or solar panels. The standard
unit uses a 1.5 kW single-phase
electric heating element. The carbon
steel boiler is internally vitrifi ed with
2 coats of SMALGLASS and has a
magnesium anode; it also has a rigid
plastic (ABS) outer coating.
3.2. CONSTRUCTION FEATURES
• Steel tank with double-layer
vitrifi cation.
• Condenser wrapped around the
outside of the boiler, free from fouling
and gas-water contamination.
• Auxiliary coil for use in conjunction
with boiler or solar panels.
• Integrated NTC probe for water
temperature monitoring.
• Outside air probe for inspiration
• Automatic heating element
activation when temperatures are
not suitable for the heat pump.
• Anti-corrosion magnesium anode.
Hydraulic connections located at
the rear.
• Thick polyurethane foam (PU) heat
insulation.
• Outer coating in RAL 2006 grey
plastic material.
• R134a environmentally friendly gas.
• 1.5 kW 230 V electric heating
element.
• IEC power supply connector with
insulating sheath .
• High pressure safety devices.
• Alternative hermetic compressor.
• Centrifugal fan with fl ow rate
regulation.
• Support handles for easy, safe
transportation.
• EN 255 - 3: the reference standard
relating to domestic hot water
production.
• IEC 60335 - 2 -21: the reference for hot
water accumulation requirements.
• IEC 60335 - 2 -40: heat pump
requirements for air conditioners and
dehumidifi ers.
• EN 55014 - 1: immunity requirements
for domestic appliances, power tools
and similar equipment.
• EN 61000 - 3 - 2/3: compulsory
standards for the containment of
harmonics and voltage fl uctuations
at 50 Hz.
3.3. ELECTRIC CONTROL
• Water set point adjustment.
• Outside air temperature.
• Self-diagnosis with low/high pressure,
water overheating and probe
disconnection alarms.
• Operating hours recording, with
control of minimal interval times
between consecutive compressor
start-ups.
• Parameter setting from the keypad.
• Heating element control in
• manual mode, or automatically
integrated mode for low outdoor
temperature values.
• Activation of the anti-bacterial
treatment cycle to eliminate
legionella and prevent it from
forming.
• User display for setting the operating
mode and the various parameters
with varying degrees of accessibility,
by means of a password.
