Food preservation in photovoltaic cold storage presents various practical technical problems.
The high cost of photovoltaic generators requires the optimization of electrical consumption to reduce the initial investment to the lowest possible figure.
The equipment's life should be long, especially for the batteries which are often the weakest element of the technological chain.
That's why it's important to conceive a system which relies, as little as possible, on the batteries.
It is necessary to conceive reliable equipment having simple and light upkeep procedures for isolated places.
The only currently existing products using photovoltaic cooling are simple refrigerators or freezers supplied by standard photovoltaic generators.
These devices are conceived for domestic applications in rural electrification programs, or for preserving vaccine in dispensary equipment programmes.
They supply limited storage volumes (max. 300 liters) and large charge electric consumptions.
The result expected is the development of a high performance photovoltaic refrigerating system, reliable and minimal in cost, well suited to the needs of small agroalimentary preserving units, in developing countries.
A cold room adapted to needs will be consist of two joined cells : - one cell at +1 degrees C ; volume = 2.5m3 for storage of fish, meat, game - one cell at +6 degrees C ; volume = 2.5m3 for storage of fruits and green vegetables The expected efficiency is an electricity consumption of 4500[Wh/day] in difficult climatic conditions.
