How it works ?:

Most air conditioners and refrigerators use the compression cooling circle. The basic thermodynamic principle lies in deflation of gases and liquids: When a gas/liquid deflates it extracts heat from its environment. Extracting heat means cooling. So when a gas/liquid deflates, it creates a cool environment.

The cooling cycle now has to provide a high pressurised gas/liquid which can deflate. The higher the pressure of the gas/liquid, the more cooling will be achieved.

So a compressor compresses the gas to a high pressure, it is easier for the compressor to compress a gas in comparison to a liquid, which means less power is needed for the compressor. During compressing the gas gets hot.
The condenser’s job is now to cool the hot gas down to ambient temperatures, this consists of a string of copper pipes and a fan which cools down the gas within the copper pipes using ambient air. This process changes its state from gaseous to liquid.

The next in the process is the expansion valve (in essence a very small hole which opens for a short time and lets the liquid pass through in small amounts). This process also acts as a barrier against the compressor, so the compressor continues at all times to pressurise the gas. The liquid starts to deflate.
Thereafter the evaporator deflates the liquid completely and changes its state back from liquid to gaseous. This process of deflation and change of state extracts heat from the environment. It cools! A fan in front of the evaporator blows air around the copper pipes. The air gets cooled down and can now be transported to the users.
The trick is to use the right gas/liquid as refrigerant. It needs to be gaseous at low temperatures and it needs not be dangerous (non-explosive and environmentally friendly) -SolarCool™

The well-known air conditioner in compressor technology is enhanced with a proprietary developed solar panel and the compressor modified. The “trick” lies in the use of the ideal gas law:

 

p * V = Rs * T

 

The product of pressure (p) and volume (V) is proportional to its temperature. The special gas constant Rs defines the exact relationship for the respective gas.
Once the gas gets compressed it gets hot. Everybody who has pumped up his bicycle has experienced that holding a hot air pump in his hand. Logically, the inverse conclusion says that you can compress gas by heating it up. And exactly that is the trick of SolarCool. The gaseous refrigerant (here R410 and not air) is slightly compressed and then heated up in the solar panel upwards of 100°C. The further process is as shown above for standard compressor conditioners.
The hotter the sun shines, the more the solar panel takes over compressing of the gas and the more power is saved. The compressor acts now mainly as a pump providing the necessary cycle flow.
