3.1 Running Principle
The Thermodynamic Solar System
ECO
is an equipment based on the principle of compression
refrigeration - Carnot's principle - which we call the Thermodynamic Solar Systems: Solar Panel and
a Heat Pump. The solar panel, which is the main component, placed outside ensures the capture of
energy on:
a) Direct and diffuse solar radiation;
b) Outdoor air, by natural convection;
c) The effect of the wind;
d) Rain water.
The temperature difference caused by the mentioned external agents, guarantees that the R134a
(ecological refrigerant) evaporates inside the solar panel.
The absence of glass on the panel allows to increase the thermal exchanges by convection.
After passing through the panel, the R134a is aspirated by the compressor, which raises its
temperature and pressure, which in turn is transmitted to the water circuit through a condenser
external to the tank.
Before the R134a returns to the solar panel, a choke must occur, that is, through a thermostatic
expansion valve the pressure is reduced and the fluid reaches its liquid state again, thus completing
the cycle.
This facility with which we combine technology with a law of nature (change of state of a fluid),
demonstrates the veracity and potential of
