Improvement to the Design of a Solid Absorption Solar Refrigerator
Abstract
The paper presents the highlights of the design of an existing solid absorption solar refrigerator, using CaCl2 stabilised with CaSO4 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.
