At UNICAMP Hospital there is an installation of an absorption refrigeration system for ice production. In these systems, it is important to know how each operation parameter influences the exergetic efficiency. Some operation parameters were studied: the pressure (temperature) of condensation of the vapor that enters in the generator, the flow of water in the evaporative condenser, the flow of water to ice formation, in the evaporador, and the time of cycle of ice formation. The present work intends to show, for this case and for the range of studied operation, how these parameters may influence the exergetic efficiency through the two levels experimental design. The obtained results show, also that the interactions of this parameters with others in study are also important.
