Performance assessment of a two-bed silica gel-water adsorption refrigeration system driven by solar thermal energy is carried out under a climatic condition typical of Perth, Australia. A Fourier series is used to simulate solar radiation based on the actual data obtained from Meteonorm software, version 7.0 for Perth, Australia. Two economic methodologies, Payback Period and Life-Cycle Saving are used to evaluate the system economics and optimize the need for solar collector areas. The analysis showed that the order of Fourier series did not have a significant impact on the simulation radiation data and a three-order Fourier series was good enough to approximate the actual solar radiation. For a typical summer day, the average cooling capacity of the chiller at peak hour (13:00) is around 11 kW while the cyclic chiller system coefficient of performance (COP) and solar system COP are around 0.5 and 0.3, respectively. The economic analysis showed that the payback period for the solar adsorption system studied was about 11 years and the optimal solar collector area was around 38 m2 if a compound parabolic collector (CPC) panel was used. The study indicated that the utilization of the solar-driven adsorption cooling is economically and technically viable for weather conditions like those in Perth, Australia.

For the climatic condition of a tropical country like Bangladesh, solar heat driven adsorption cooling seems to have great prospect. Installation cost is one of the foremost drawbacks of such a system. Although, once installed, system maintenance and operation cost is negligible. Besides, the solar unit can not only support as a cooler for adsorption space cooling purpose during summer season but also as a source of hot water supply for domestic use during the winter season. A conventional two bed basic adsorption chiller, driven by solar heat run by silica gel-water pair as adsorbent and adsorbate respectively, has been investigated for the climatic condition of Dhaka 6 4 23 N (latitude), and 3 2 90 E (longitude). 30 enhanced compound parabolic concentrator (CPC) collectors each of area 2.415 m 2 along with a hot water storage tank of volume 2.197 liters is optimum for considered climatic condition. With such a unit 30.27°C continuous water supply during the peak hours can be assured, with the storage of 44.77°C of hot water in the month of January.

The study investigates the performance of an adsorption chiller driven by thermal heat collected from solar collectors' panel with heat storage. The heat is reserved in a storage tank and the reserved heat is used to drive the adsorption chiller. The investigation was carried on the climatic conditions of Dhaka, Bangladesh. Heat transfer fluid goes from collectors to adsorption cooling unit, then from adsorption cooling unit to storage tank. It is seen that heat storage is more effective than the direct solar coupling; however, it requires more collectors depending on the size of the storage tank. The analysis shows that cycle time is one of the most influential parameter for solar driven adsorption cooling system. It is seen that the size of collector can be reduced if proper cycle time was adjusted. The analysis also revealed that the system with 22 collectors (each of 2.415m 2 ) along with 1000s cycle time provides better performance for the base run conditions. It is also seen that the solar driven adsorption chiller with heat storage works well beyond the sunset time.
