A big question on Heating, just a solar panel and a fridge
solar thermodynamic apply in situations where you require hot water at
60 º C, such as central heating, homes with radiant floor heating,
production of hot water, heating swimming pools and so on. "
Let us tell the truth...if we could resolve once and for all (and so cheap) the problem of heating water, we could say goodbye to oil and gas dependency.
The incessant wander between real or supposed solutions, took me to bump into a Spanish (but uses a French patent developed two decades ago) that produces solar thermo dinamic panels.
"The thermodynamic solar panels - we read in a brochure - are the combination of traditional solar panels and thermal known heat pumps."
Is for me, and I go forward in reading.
It's interesting to note just how the solar panels used in this system are easy to install because it lighter and smaller. Each panel weighs 8 kg and measures 200cm x 80cm.
They are also able to capture solar energy by both sides, so they capture an area of 3.20 m2.
Other news that is "attractive" is that they work with the sun, but even with the wind and rain, almost always (including night? Yes, including night!):
"Unlike traditional solar panels or heat pumps heat, solar thermodynamic systems are those that best exploit the energy of the environment, be it the solar radiation, heat wind or rain. "
How does it work? The simplest explanation I have found here:
"The panel captures the warmth of the sun, wind and rain and heats the refrigerant that raised its gaseous state. Then the strives gas compressor and compresses, thereby raising the temperature of fluid up to 100 degrees. The heat is transferred to water through a heat exchanger."
"The system - supports Silvino Fernandez, CEO of Solar PST - has proved efficient and versatile. The advantages are undoubtedly linked to the operation extremely simple and the type of panel, very light and durable, that does not require any maintenance. "
The system has very high energy efficiency, with savings of 65% compared to other traditional systems and the payback period is estimated in within 4 years.
This is actually a refrigerator on the contrary that produce hot water. In the circuit circulates a refrigerant (134-A, 407) between a temperature of -5 and -15 degrees.
Very cool idea and hope to hear more about it i the future.
