AB - The feasibility of solar assisted air conditioning in an office building  under Tripoli weather conditions is investigated in this paper. A  single-effect lithium bromide absorption cycle powered by means of flat-plate  solar collectors was modeled in order to predict the potential of the solar  energy share. The cooling load profile was generated by using an detailed  hourly based program and Typical meteorological year for Tripoli. System  performance and solar energy fraction were calculated by varying two major  parameters (collector’s slope angle and collector area). The maximum solar  fraction of 48% was obtained by means of 1400 m2 of collector surface area.  Analysis of results showed that, besides the collector surface area, the main  factors affecting the solar fraction were the local weather conditions  (intensity of incident solar radiation) and the time of day when the plant  was operated.
