3. SPECIFICATIONS
3.1. Running Principle
The thermodynamic solar system
ECONOMIC is based upon the refrigeration
working principle by compression – Thermo-
dynamic principle of Carnot – which we de-
signate by Thermodynamic Solar Systems:
solar panel and heat-pump.
The Solar Panel it’s the main component,
shall be placed outside. Is also responsible
for collecting the energy from:
• Diuse and direct solar radiation;
• Air, by natural convection;
• The wind eect (almost always availab-
le);
• Rain.
The temperature gradient between the ex-
ternal agents mentioned above and the uid
inside the solar panel, makes the uid to eva-
porate on its inside. The absence of glass in
the solar panel allows for an increased ther-
mal heat exchange by convection.
After circulating in the solar panel, the uid
is aspirated by the system’s mechanical com-
ponent, the compressor, which will increase
its temperature and pressure; then the tem-
perature is transferred to the water circuit by
a heat exchanger.
Before the uid returns to the solar panel it’s
pressure and temperature are reduced by
passing thru a expansion valve, completing
the cycle.
The easy way we combine technology with
a law of Nature (change of state of a uid),
demonstrates the true potential of the THER-
MODYNAMIC SOLAR SYSTEM – ECONOMIC.

3.4. Safety and Control Devices
3.4.1. Safety Thermostat
The safety thermostat is set by the supplier
to ensure that the water temperature in the
storage water heater does not exceed the
standard value.
Should the temperature exceed this value,
the thermostat switches o the thermo-
dynamic system. Switching on is done ma-
nually by qualied sta, after analysing the
reasons for the switch o.
3.4.2. Protection against corro-
sion
The hot water cylinder in this equipment is
made of stainless steel AISI444.
Besides being resistant to corrosion, the
storage water heater has in addition a mag-
nesium anode that should be checked pe-
riodically by the installer..
3.4.3. Expansion Vessel (not su-
pplied)
O vaso de expansão é um dispositivo dest-
The expansion vessel is a device whose pur-
The R134a is a HFC uid, thus not harmful
to the ozone layer. It has great chemical
and thermal stability, low toxicity, non-in-
ammable and is compatible with most ma-
terials.
The following graphic depicts the behaviour
of pressure according to evaporation tem-
perature:
pose is to compensate for the increase in
water volume due to temperature rise and
to reduce the consequence of any water
hammer eect
Installing this device is a re-
commended procedure for
a correct installation of the
equipment.
Installing this device is the
responsibility of the installer.
As a general rule it is instal-
led in the cold water pipe.
3.4.4. Safety Group
The safety device allows the system to
be protected against anomaly situations:
cold water supply, hot water owing back,
emptying the storage water heater and
high pressure. The valve is calibrated to ac-
tivate at 0.7 MPa.
In order to drain the water in the storage
water heater, you should close the supply
valve and open the discharge valve.
The safety valve discharge pipe must be
open into the atmosphere, driven to the sink
because the valve may drip or even dischar-
ge water.
The safety valve must be opened regularly
to remove impurities and check that it is not
blocked. The discharge pipe must be instal-
led in a vertical position and not placed in a
freezing location.
DANGER
The installation of the safety
group must take into consi-
deration the right direction of
the hydraulic ow.
The right direction is represen-
ted by an arrow on the com-
ponent. An incorrect installa-
tion poses a danger to people
and to the equipment.

The pressure reducing valve must always be
installed upstream from the safety device,
and ready to activate in situations when the
pressure in the circuit exceeds 3 bar. This
valve comes with a pressure gauge.
4. INSTALLATION
Assembly sequence:
• Thermodynamic solar panel attachment
• Set-up of the hot water cylinder + ther-
modynamic block
• Refrigerant connections
• Hydraulic connections
• Electric connections
4.1. Thermodynamic Solar Panel
Installation
The nature of the site and the inclination an-
gle where the panels are installed are impor-
tant factors to consider. In order to benet
the most from the sunlight exposure, the
panels should have a pitch between 100and
850relative to the horizontal plane, and pre-
ferably oriented to the south (on the north
hemisphere).
The panel already comes with 6 holes for M8
in the lateral bends. The distance between
holes in the place where the panel rests
should coincide with the holes made in the
panel.
DANGER
The installation of the pressure
reducing valve must take into
consideration the right direc-
tion of the hydraulic ow.
The right direction is represen-
ted by an arrow on the com-
ponent. An incorrect installa-
tion poses a danger to people
and to the equipment.
WARNING
Fixation in at least 6 points (3
points at the top and 3 points at
the bottom) is mandatory!
The lack of at least one of these
points may cause deformities
in the panel and, in some cases,
may cause the panel to move
away from the place of instal-
lation.
