Thermodynamic Systems

The Solar PST system guarantees the production of hot sanitary water, central heating and swimming-pools providing the maximum energy efficiency 24 hrs a day, thanks to its revolutionary working principle.
The Thermodynamic Solar Collector technology offers high performance even at night, with rain, or on overcast days.

The Thermodynamic Solar System combines the two best existing technologies today, the heat pump and solar thermal collector, getting the best of both. Heat pumps are very efficient systems, but the heat produced varies with temperature fluctuations of the environment.
Solar thermal collectors are the best heat source for heating but depend on sunny days with high temperatures, being totally ineffective when the sun is absent. The thermodynamic solar technology, combining elements of both systems, has overcome these deficiencies.

The working principle is based on the Thermodynamic laws, discovered by the french physician Carnot in 1824. This principle takes advantage of the physical properties of a refrigerant gas that, when changing its state, it is capable of transmitting the heat absorbed by the collectors down to the cylinder where the water is stored.
The fluid refrigerant enters the panel at -10ºC that changes its state due to the heat previously captured from the ambient temperature which is present in the direct and diffuse solar radiation, external air by natural convection, wind effects and rainwater.
The hot gas comes out of the panel and goes into the compressor that increases the refrigerant gas temperature and pressure. Then the gas yields the heat to the water stored in the cylinder up to 50ºC.
As it cools, the refrigerant condenses into liquid and flows through the expansion valve that measures the amount of the liquid refrigerant that will be sent to the panel. Thus the cycle starts all over again.

System consumption is summarized to a refrigerant compressor which circulates the fluid, there are no fans to assist in the evaporation process or stops defrosting unnecessary energy consumption as with heat pumps.
