The paper presents the highlights of the design of an existing solid absorption solar refrigerator, using CaCl 2 stabilised with CaSO 4 as the absorbent. The performances are also discussed. The sources of poor performance were identified as high thermal and pressure inertia of the system, high heat loss coefficient, and low absorbent thermal conductivity. Based on these, measures taken in the design of a new model refrigerator, to improve the refrigerator performance are then presented.
