Solar powered absorption refrigeration system

Claim 1

An absorption refrigeration system comprising: an evaporator, an absorber, a generator and a condenser all connected in a closed, continuous cycle referigeration circuit with relatively concentrated absorbent solution flowing to the absorber to absorb water vapor from the evaporator and relatively dilute absorbent solution flowing from the absorber to the generator to be concentrated with concomitant release of water vapor to be conducted to the condenser, said generator including a solar collector for providing thermal energy to the absorbent solution to be concentrated, said solar collector including a series of inclined channels into which said relatively dilute solution is introduced in such a way that the channels are not completely filled with solution and a vapor space is maintained at the upper portion thereof, the exterior surface of said channels being provided with a solar absorbing surface; means for directing water vapor to said condenser; and means for conducting relatively concentrated absorbent solution to said absorber.
