A Refrigerant gas passes through the solar panel at a temperature of -20ºC, thereby allowing the collection of the energy from the sun, rain and wind. As the fluid is running at negative temperatures, it collects the heat from the air by natural convection, working also at night. It’s performance will be greatly increased with solar radiation.
The fluid is then compressed in the Solar Box which causes the fluid temperature to increase. This heat is then released into the circulating water by way of a high performance plate heat exchanger.
Finally, the fluid goes through an expansion valve and will evaporate into the aluminium solar panel and the process repeats.
