4.3 Thermodynamic block
We call Thermodynamic Block to the
component that transfers the Energy caught
by the solar panel in heat transferred to the
water.

Fluid , R134a
550 g
It structure is made of galvanized steel that
have the compressor, heat exchanger,
expansion valve, thermostat, pressure
switch, electric resistance.
The front part of the block has two valves, of
2 and 3 ways destined for the panel
connections (3/8'' - Aspiration; 1/4'' - liquid)
Fig. 6 Thermodynamic Block (main components)
The Thermodynamic Block is connected to
the hot water cylinder through eight M10
screws.
4.4 Fluid, R134a
R134a is an ecological fluid is not harmful to
the ozone layer. It has a high thermal and
chemical stability, low toxicity, is non-
flammable and is compatible with the
majority of materials.
