Abstract
The present invention relates to an improvement of a solar refrigeration system. The solar refrigeration system has been improved by combining a solar collector-generator and a heat exchanger into one unit to increase the performance efficiency of the system by eliminating heat losses. The solar collector-generator comprises a tube and header arrangement including a plurality of double-walled tubes, each consisting of an outer pipe and an inner pipe, the inner pipe defining a passage for a high temperature refrigerant-lean or weak solution, whereas, the outer and inner tubes defining therebetween a passage for a low temperature refrigerant-rich or strong solution.
