heal.abstract	The hour by hour performance of solar driven H2OLiBr absorption units, operating as refrigerators or heat pumps, is predicted during a typical year in the Athens area. The thermodynamic analysis is based on a developed model, which simulates the exact absorption thermodynamic cycle. The hourly values of solar radiation and ambient temperature are estimated from numerical processing of related measurements corresponding to about 20 years. In the case operation as a refrigerator, it has been found that the theoretical coefficient of performance varies during the year from 86 to 96%, and the calculated maximum values of the specific cooling power for January, March, May, July, September and November are 155, 260, 369, 363, 277, and 197 W m-2 per collector, respectively. In the case of operation as a heat pump, the theoretical heat gain factor has been found to be practically constant during the typical year ({reversed tilde equals} 192%) and the calculated maximum values of the specific useful thermal power for the above mentioned months are 264, 504, 825, 890, 658 and 369 W m-2 per collector, respectively. © 1989.	en
