Abstract
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 23°46′N (latitude), and 90°23′E (longitude). 30 enhanced compound parabolic concentrator (CPC) collectors each of area 2.415 m2 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.
