A solar heat driven cooling system utilizes abandoned solar radiation, plays an important role in preservation of primary energy, prevents sound pollution and chlorofluorocarbon (CFC) /hydro-chlorofluorocarbon (HCFC) free environment. Other than the installation and commissioning cost, the running cost of this system can be reduced to its bare minimum by maximum exploitation of the collected solar energy. This article points out a way how collected heat energy can be properly utilized to run a conventional two bed solar adsorption cooling system to produce optimum cooling energy ensuring prolonged coverage. Increased solar thermal units can enhance heat collection up to 864.1006 MJ/75.68 m² of collector area. Enlarged storage tank provides backup for longer working hours, 14 hours a day. On the other hand, a smart choice of operating conditions can ensure a higher cooling capacity of 16.1 kW/2.197m³ heat storage tank at peak hours and a comfortable, steady cooling effect over a relatively longer duration. Proper management of collected energy can turn out to be an economic gain factor in a developing country like Bangladesh. It could save roughly BDT 9324 ≈ $116.55/year for only 1 RT space cooling purpose. Moreover, it lowers CO² emission and preserves primary energy and electricity.
