ABSTRACT

In this contribution, a study of the thermal losses effect undergone by the different parts of an intermittent absorption solar refrigeration cycle using the Ammonia/Water mixture is presented. After having shown the interest of the intermittent cycles through the discussion of the problem of the adaptation of these cycles to solar energy, mass and thermal assessments for each compartment of the installation were established for the two cases without and with thermal losses. The resulting differential equations system is solved numerically. The theoretical results obtained concern the temperature variations, the vapor flow as well as the compositions of the rich and the poor solutions.
