Thermodynamic Solar Technology

The thermodynamic solar systems use heat pump technology supported by solar energy to generate domestic hot water and heating by capturing solar and environmental energy to heat water in a efficient way, with very low energy consumption compared to conventional systems.

Why thermodynamic solar panels are different?

  • Obtain hot water under any atmospheric condition, functioning at night time as well as in wet or windy weather
  • Works continuously 24 hours a day 365 days per year under all weather conditions
  • Without glass or electrical components
  • Ventilation and de-icing unnecessary
  • Don’t need maintenance or cleaning
  • Dirtiness does not affect the output of the panel

 

How does Solar Thermodynamic Heat Pump Technology Work?

A refrigerant fluid at low temperature (that could be less than 0ºC) circulates in the interior of the thermodynamic panel. The fluid captures the incidental solar radiation in the panel as well as other environmental energy. The thermodynamic cycle condenser transfers the heat to the water. The ecological refrigerant R134-A or R407C, which enters into the panel at a negative temperature, runs through the closed circuit situated in the interior of the panel. The difference in temperature provoked by external agents such as the sun, rain or the wind guarantees the gasification of the fluid.

The compressor sucks the heated gas and reduces its volume, raising its temperature and transmitting it to the water circuit through a heat exchanger, managing to obtain domestic hot water up to 55 or 65°C. At high pressure and after having transfer a large part of its heat to the condenser, the refrigerant fluid arrives at the expansion valve again in liquid phase. Here the pressure is reduced which means the fluid is in condition to enter into the panels once again. The valve regulates the outflow depending on its temperature. Like this, the refrigerant will be sent again, in the form of micro drops, through the dehydrated copper piping to the panels, where it will be compressed once again, and the cycle will be repeated until the desired temperature is reached.
