In this thesis, solar energy is utilized as the driving energy for an absorption cooling system, and a TRNSYS computer code is employed to simulate the operation of the system under Taiwan climate. Climate data in TMY2 form for several major cities of Taiwan are input to the simulation program. Also system operating parameters of solar collector area and the size of the system storage are varied to study there effects on the system performance. This research provides computer simulation data for the monthly solar fraction (f) as well as the seasonal solar fraction (F) for the absorption solar cooling system operated under the climate of the major cities in Taiwan. The data can provide the design needs.
