Abstract
The invention relates to a refrigeration device using solar energy. This device includes a refrigeration fluid, such as water, which circulates between the solar energy heat exchanger 8 containing zeolite, and an evaporator 2 located in a cooling chamber 1 through a condenser 6, then return to the exchanger 8 through a three way valve 7. The device includes a second channel in the exchanger 8, which channel includes a fluid, and a second exchanger consisting of a tube with fins 20 connected to a storage tank 25 containing water at various temperatures. During the day whenever the period of sunshine is not sufficient, additional heat in the form of hot water is provided to the exchanger 8. Conversely if the night temperature is not low enough, cooling in the exchanger 8 is assisted by a cooling device 23 located in the second channel. Hot water 25.degree. C. is provided by the excess heat produced by the sun at day's end.
