From the process developped and tested by CNRS LIMSI at Orsay in the years 1980, the laboratory IGT LESBAT at Yverdon les Bains conceived, developped and tested a refrigerator using the sun like only source of energy to create cold. Tha day, the solar collector generates vapor which is transformed into water by the condenser.
The night, this water goes up in the collector by generating sufficient cold to create ice in the storage.
The system is neutral with respect to the environment : no pollution.
The stock of ice preserve a temperature of conservation up to 3 days without sun ( established in sahel climate with 43 C the day and 34 C the night)
