Improved humidity extraction
The CAC project has designed a controlled atmosphere concentrator (CAC) that uses an innovative line focus reflective concentration module concept. It consists of a box containing the key components of PV concentration modules which are PV cells and reflectors. The novel system is able to get rid of degradation problems associated with reflectors in systems of this type by encapsulating the necessary organic elements. The CAC system involves humid air crossing a humidity sensor which is then transported to the entrance of the compressor via the electro-valve and air filter. Air exiting the compressor is passed into a homogeniser of pressure which transforms the sporadic flow into continuous flow. The process involves crossing a filter of salts provided with an element heater, then crossing another filter of salts where humidity retention is completed via a valve of on-pressure and an electro-valve to the CAC. Once the salts have absorbed most of the humidity, a regeneration process starts. This activates the two electro valves in order to transport air circuits and feed the electro heater with the first filter of salts.
